Saint Mary’s Looks to Future with New Brand Story 

Saint Mary’s University is looking to the future with the launch of a new brand.      

“It is time for Saint Mary’s University to assert our place boldly among the top Canadian universities and proclaim our advantages at home and around the globe,” says Saint Mary’s University President and Vice-Chancellor Dr. Robert Summerby-Murray. “This is the brand for our university and for our times. Saint Mary’s University offers a bright, ambitious vision for the future.”  

The new brand platform results from months of qualitative and quantitative research and extensive consultation with a diverse group of more than 3,000 faculty, staff, students, alumni and other stakeholders.   

The new treatment includes a logo, wordmark and tagline, ‘World Without Limits.’    

“‘World Without Limits’ is a wonderful distillation of who we are and what Saint Mary’s strives for every day. It is about investment in people, about economies, international relations and social prosperity, changes in science, technology, environment and business. It is also about acknowledging and tackling the very real limitations placed on diverse and marginalized cultures and peoples, and addressing the mental health issues that many grapple with every day. It is about Saint Mary’s bold vision and our commitment to our university community, for Halifax and for Nova Scotia,” says President Summerby-Murray.    

“More than an updated look and feel, our new brand platform is a powerful way of telling the Saint Mary’s story,” says Erin Sargeant Greenwood, Vice-President, Advancement. “Saint Mary’s offers a unique experience. We are a caring community, more typically associated with smaller universities, combined with the research and student engagement opportunities of the largest institutions. We are moving the university forward in a way that reflects our traditions and values and embraces our bright future.”

New findings of a multi-university team of researchers show that pollution from historical gold mining in Nova Scotia, Canada, persists at levels that impact the health of aquatic ecosystems, despite mine operations closing nearly a century ago.

“Mining activities from 100 years ago can still impact freshwater ecosystems today. Our work reveals that lakes may show signs of recovery from those impacts,” notes Saint Mary’s University Professor and co-author Dr. Linda Campbell. “Even so, we must remain vigilant about understanding and monitoring the legacy of those contaminated tailings in our modern ecosystems to support recovery processes.”

Over 350 gold mines operated throughout Nova Scotia between the mid-1800s and 1950. Urbanization and land development has taken place nearby some historical mining areas and people sometimes use these areas for recreational activities. Waste tailing materials with elevated and potentially toxic levels of arsenic and mercury often are associated with historical gold mining sites in Nova Scotia. The tailings can contaminate soil and aquatic sediments through water and wind movement.

This study used dated sediments from the bottom of two urban lakes located near one of the region’s largest historical mining operations. Lake sediments are a well-recognized and information-rich natural archive of past environments which allow the assessment of geochemical and biological conditions of lakes and their watersheds before, during, and after pollution has occurred.  

The study was recently published in the peer-reviewed international journal Science of the Total Environment and highlights how pollution from past gold mining combined with contemporary stressors such as climate change and urbanization may contribute to prevent complete lake recovery from century-old mining pollution.

“Past mining activities that occurred throughout Nova Scotia introduced considerable amounts of arsenic and mercury into the environment,” says lead author Allison Clark, from Mount Allison University. “Although the Montague Gold District closed to mining 80 years ago, lakes nearby still remain severely impacted.”

Currently, arsenic levels are still very high in the lake sediments—300 times above levels that are known to harm aquatic organisms. Mercury has returned to levels observed before gold mining began. This suggests that arsenic is behaving differently than mercury within the sediments at the bottom of tailing-impacted lakes.

“Mining is both a blessing and a curse,” notes Mount Allison University Associate Professor and co-author Dr. Joshua Kurek. “Society benefits but past mining activities practiced throughout Nova Scotia continue to harm ecosystems and citizens are now left with the clean-up costs.”

Additionally, invertebrates that live on and interact with the lake’s sediment have become less diverse compared with a similar reference lake, likely due to the mining pollution as well as other recent watershed stressors. Loss of key organisms may affect lake food webs, leading to issues with water quality.

Funding for this research was provided by Natural Sciences and Engineering Research Council of Canada (NSERC) and Genome Atlantic.

SMU receives federal funding for major new chemistry centre collaboration

Saint Mary’s University’s research into environmentally sustainable and cost-effective remediation of historic gold mine sites across Nova Scotia is receiving a boost in the form of a five-year partnership with Atlantic Gold, a wholly owned subsidiary of St Barbara Ltd, based in Australia.

 “St Barbara is a global gold company and is proud to own and operate the Atlantic Gold Operations in Nova Scotia,” says St Barbara Managing Director and CEO, Craig Jetson. “As we operate our business and care for our people, we are guided by our company commitments – including respecting the environment and stronger communities.

“At St Barbara doing the right thing is important to all of us. Saint Mary’s University’s research into environmentally sustainable and cost-effective remediation of historic gold mines across Nova Scotia is aligned with our commitments, including growing sustainably,” says Jetson.  “We believe in learning from the past to secure our future and look forward to seeing this philosophy applied in the important work being done by Saint Mary’s University.”

“This is a significant investment by St Barbara, reflecting the importance we place on finding solutions to actively manage and neutralise the impact of our mining operations, because we care about the environment and the planet,” says Jetson. “We have recently committed to achieving carbon neutrality by 2050 and are pleased to see our Atlantic Gold operations leading to deliver on this promise by 2025.We look forward to updates on the important work being done by the Saint Mary’s University team and thank them for their commitment to this project.”

The funding is part of a new five-year partnership between Saint Mary’s University and Atlantic Gold with the first payment of $200,000 being delivered late in 2020.

There is a long history of gold mining in Nova Scotia, and methods used 100 years ago are now known to be damaging to the environment. The goal of the Saint Mary’s University research team, led by Dr. Linda Campbell, is to use its proven expertise from previous studies of former mine sites to develop a low-cost remediation strategy. This new strategy is designed to support the natural recovery of wetlands and shallow water environments impacted by 100-year-old contaminated tailings.

“I want to thank Atlantic Gold for their strategic partnership and financial investment in advancing world-leading research that benefits both our local and global communities,” says Saint Mary’s University President Dr. Robert Summerby-Murray. “This partnership is an exemplar of innovation with a community-centred approach. It addresses a challenge with an immediate local connection but with far-reaching national and international implications.”

The scope of the damage to the environment from abandoned gold mines is wide, encompassing 300 abandoned mines across the province in both remote areas and backyards. Contamination from the arsenic and mercury used in historic gold mining can adversely affect human health and present severe environmental contamination risks.

“Saint Mary’s University is proud to be a part of the solution when it comes to remediating the damage done by historic gold mining practices across the province,” says Saint Mary’s University Vice-President, Academic and Research, Dr. Malcolm Butler. “Dr. Linda Campbell and her team are employing innovative research to create remediation techniques that minimize the impact on the environment, wildlife and humans. This research has the potential for significant applications in Nova Scotia, the rest of Canada and the world.”

Mining in Nova Scotia began well before most environmental legislation, and untreated tailings were placed in wetlands and shallow-water areas. Over the subsequent decades, abandoned tailings were left in place, with limited natural recovery taking place. Research at Saint Mary’s completed in 2015-2019 shows that sediment samples from legacy gold-mine tailings in N.S. wetlands remain contaminated and are still severely toxic to aquatic invertebrates.

“We are currently wrangling with the consequences of decisions and actions made a long time ago,” says Dr. Linda Campbell. “Our goal is to ensure legacy arsenic and mercury contaminants will not continue to be a problem for Nova Scotians for another hundred years. We are looking forward to working with Atlantic Gold and our other collaborators to undertake the necessary research and development to help restore ecological vitality of impacted wetlands.”

Dr. Campbell is joined by Senior Project Research Manager Dr. Emily Chapman and a team of researchers that will look at new ways to remediate sites using more effective and less invasive techniques than traditional remediation methods. Those traditional methods can be destructive to the areas that need to be protected. A proof-of-concept study of a new method, which will use a thin layer of a reactive material, is promising in its ability to limit risks of legacy gold mine tailings without compromising wetland function. It is this approach that is being investigated by the research team.

Dr. Emily Chapman

“Wetlands are incredibly important ecosystems, and these sites need help to recover. It is about finding the right blend of ingredients that will reduce the mobility and toxicity of contaminants in the sediment, without adding so much material that wetlands are infilled and destroyed,” says Dr. Chapman. “Having worked on the development of innovative approaches for dealing with these risks for several years, I am pleased to see that this issue is getting some recognition.”

Remediation is a very expensive undertaking, with a 2019 estimate of $48 million to clean up the Crown land portion of two Nova Scotia legacy tailing sites. If proven effective, the new method proposed by Dr. Campbell and her team will have an immediate economic benefit as a more cost-effective, non-intrusive ecological and human health option for impacted wetlands across Nova Scotia and similar sites around the world.

Dr. Campbell is a professor in the School of the Environment at Saint Mary’s. In her research, she uses multi-disciplinary approaches to improve our understanding of anthropogenic and natural impacts in the environment, with a focus on aquatic ecosystems.

Atlantic Gold, a wholly owned subsidiary of St Barbara Ltd, operates the Moose River Gold Mine near Middle Musquodoboit, Nova Scotia, and is permitting three more mines along Nova Scotia’s Eastern Shore. The Company is investing in a research partnership with Saint Mary’s University to explore the remediation of historic gold mine tailings in freshwater ecosystems.

Saint Mary's Engineering Team Victorious at Atlantic Engineering Competition

Saint Mary’s students Amy Kehoe and Andrew Ollerhead

Saint Mary’s students Amy Kehoe and Andrew Ollerhead

Congratulations to Amy Kehoe and Andrew Ollerhead for winning the Junior Design competition at the Atlantic Engineering Competition, hosted virtually by the University of Prince Edward Island last month. The pair were competing in a field of 11 Atlantic university teams.  

Only knowing in advance that their topic would focus on either Prince Edward Island aquaculture or agriculture in some way, the Atlantic competitors received their instructions and a box of supplies that included cardboard, coat hangers, Styrofoam balls, straws and duct tape. Then, teams had just six hours to build a prototype to solve this agricultural problem facing Island farmers and present it to the judges:

Problem

Due to the lack of natural pollinators, many personal gardens and greenhouses suffer from poor plant health and low crop yield. To fix this, humans have developed artificial pollination methods. A device that can mechanically pollinate a tray of plants is required.

Challenge

Design a device or system that is capable of pollinating the provided tray of plants. The priority is to pollinate the highest number of plants with a sufficient amount of pollen under the designated time limit. 

The pair quickly got to work brainstorming ideas on a white-board, narrowing their ideas down to three before coming up with their strategy.

“Within the first hour, we chose a design and started working out the mechanics of building it,” Kehoe says.

Their project design consisted of a cardboard frame with two poles to allow a set of three hoppers that would slide open or closed depending on the position of a sliding plate with holes that would align.

“Our goal was to cover the bottom of nine Styrofoam cups with salt; the cups were on a three-by-three grid, which is why we chose the shape we did,” Kehoe adds. “We used an elastic to make sure each position was the one we wanted; we had to use string to make anything move on the machine.” 

Contest rules specified that the device had to remain on the table, and only one person could operate the device. The teams could not physically touch the tray of cups, and the pollen had to be dispensed in a controlled manner. 

“Our pollinator can pollinate nine plants, but since a greenhouse doesn’t normally have nine plants, we have to be able to scale it up easily,” the team explains. “We had to think of those things in the design process. That’s why we chose this design. We made ours out of cardboard, but we discussed that we would use plastic in real life, and we looked up costs of materials.”

“The prototype is part of it, but a big part is the presentation,” Kehoe adds. “Talking in front of an audience, and more importantly, coming up with the design and thinking of how to translate this to a real-world application.”  

In preparation for this event, Engineering instructor Luke MacDonald coached the Saint Mary’s teams on creating professional presentations. He ran a practice competition to help the students prepare to work under pressure. 

“These competitions give students the opportunity to use the skills they have learned in various courses on real-world problems,” MacDonald says. “Students work on a design problem in teams to come up with solutions—it’s a good experience for them, and helps build useful skills which they can use in their future careers.”

Both Kehoe and Ollerhead are in their second year of Engineering. Ollerhead plans to finish a Bachelor of Science in Engineering before continuing onto studies in Mechanical Engineering.

As for Kehoe, she plans to take Electrical Engineering after finishing her BSc but first hopes to travel next year to volunteer in her role as a Council Youth Commissioner for Nova Scotia at an international scouting centre if Covid-related travel restrictions are lifted by that time.

The pair will virtually compete at the Canadian Engineering Competition 2021 later this month, which will be hosted by the University of New Brunswick.

Saint Mary's science researcher part of global soil biodiversity network

Dr. Erin Cameron

Dr. Erin Cameron

Dr. Erin Cameron, Saint Mary’s researcher and professor in the Department of Environmental Science, is a co-author of a just-published paper in Science Magazine titled “Tracking, Targeting, and Conserving Soil Biodiversity.”  

This international project follows a paper Cameron authored in Conservation Biology last year, which determined that there are mismatches between aboveground and soil biodiversity globally, and thus protecting aboveground diversity may not sufficiently reduce threats to soil biodiversity.

“We are working on building a global biodiversity network focusing specifically on soil,” says Cameron. “Tracking the biodiversity of soil is an important part of global environmental conservation work, and this is a long-term project that’s just beginning.” 

“There is still a lot to discover about soil biodiversity and how human activities are impacting it. Organisms that live in the soil are a vital part of a functioning ecosystem.”  

Cameron also had a paper published as the cover story in Science Magazine last year, in which she explained her work studying the global diversity and biogeography of earthworms. 

Saint Mary’s University professor goes above and beyond with astronomy research and teaching

Dr. Luigi Gallo is a professor in the Department of Astronomy and Physics at Saint Mary’s University in Halifax.

Dr. Luigi Gallo is a professor in the Department of Astronomy and Physics at Saint Mary’s University in Halifax.

Black holes are voracious eaters that gulp up everything they can, from stars and dust clouds to other space debris. Supermassive black holes are hundreds of thousands of times the mass of the sun. Understanding the behaviour of these astronomical objects can be complicated.

Dr. Luigi Gallo’s research can attest to that. Through his research on black holes and supermassive black holes, Dr. Gallo, a professor and researcher in the Department of Astronomy and Physics at Saint Mary’s University in Halifax, has helped gain new understanding of the topic.  

“Certain kinds of black holes eject material, and this is more widespread than initially thought,” said Gallo. “We have found that black holes and their host galaxies have an interesting relationship that grows and evolves together,” he says.

Gallo is part of an esteemed international team working with NASA and the Japan Aerospace Exploration Agency (JAXA), and is also part of XRISM, the international X-ray Imaging and Spectroscopy Mission. His work has led to groundbreaking discoveries that altered scientists’ understanding of black holes.


Sophia Waddell – Faculty of Science from Saint Mary's University.

“We are studying high-energy X-rays emitted from the region around the black hole. Fundamentally, these X-rays are just light you cannot see with your eyes,” explained Gallo.

Since the X-rays do not penetrate Earth’s atmosphere, NASA and JAXA, are building the XRISM satellite, which is set to launch into space in February 2022, to study X-ray sources in the universe.  The primary instrument on XRISM is a calorimeter called Resolve.

It’s like a supersensitive prism that breaks white light into colours,” he explained. “But we are looking at X-ray colours as opposed to visible colours. How a prism will separate the white light into 6-7 distinctly coloured band, the calorimeter is so sensitive it will show separations within each of the bands.”

Gallo says the XRISM will perform high-resolution X-ray spectroscopy in the medium around black holes and in clusters of galaxies, and can reveal the composition of the material, temperature and how it moves — smooth, spiralling, or turbulent.

These missions can take decades to launch, but a revolutionary observation from the previous 2016 Hitomi (ASTRO-H) satellite mission pushed the timeline of XRISM into production.

“We learned through Hitomi while observing the Perseus cluster [a cluster of galaxies] that the environment was not as turbulent as we might have expected,” said Gallo. “The composition of the material was different, so all these kinds of things showed us that our models needed to be improved.

Passing it on 

Dr. Gallo completed his PhD at the prestigious Max Planck Institute in Garching, Germany, followed by postdoctoral research in Japan. He later joined the Saint Mary’s faculty and works with the Canadian Space Agency on these missions.

His passion for astronomy was born at an early age, and he shares his love for space with his students. “I was one of the kids that always looked up instead of looking down,” he said.

“One of my favourite parts of being a teacher is working with students on research projects. You measure your success through the success of your students, seeing them figure things out and even find better solutions.”

A professor at Saint Mary’s University since 2007, Dr. Gallo has invited students to work with him on his current projects as a way to learn more about current research methods, and has helped many students get their own original papers successfully published, an exciting milestone.

But one of the greatest aspects of teaching at Saint Mary’s University is the smaller classroom environments, says Gallo, where students appreciate the opportunity to stand out from the crowd in a warm, welcoming setting.

“As a smaller university with around 7000 students, Saint Mary’s is unique because it has a level of excellence in research that stands up to any large institution in the country,” he said. “Our astronomy department has as many researchers as much larger schools.”

“It often shocks the undergraduate students when I know their names, even if they haven’t taken a class with me,” said Gallo. “We have a strong sense of community, where students feel they can immediately begin making vital contributions.”

A partnership between Saint Mary's University, TRIUMF, and the University of Manitoba for the Canada Foundation for Innovation (CFI) project CANREB, has borne significant fruit when it comes to radioactive isotope research.

Saint Mary's University leads this national CFI project for rare isotope research at Canada's particle accelerator centre, TRIUMF in Vancouver, British Columbia. On December 6, 2020, the CANREB (CANadian Rare isotope facility with Electron Beam ion source) team of scientists and engineers achieved a major milestone accelerating for the first time a radioactive isotope beam through the CANREB facility and delivered to the IRIS experiment in the ISAC-II experimental hall. The IRIS facility is also a SMU-led CFI project that unveils the secrets of the rare isotopes with nuclear reactions.

"CANREB opens an exciting new era for exploring the rare isotopes in nature. It enables the capacity to accelerate, with high-purity, high-mass isotopes," says Rituparna Kanungo, Principal Investigator for the CANREB project, Professor of Physics at Saint Mary's University and a TRIUMF Affiliate Scientist. "CANREB unlocks new opportunities for research and the training of students and postdocs from across Canada and around the world. The project has been a strong team effort from its conception to its realization. I am thankful to everyone in the team for making CANREB a success story."

The first beam – copper-59, at a charge state of +19 – was manoeuvred through a multifaceted sequence of several complex state-of-the-art, custom built components that were all designed by the CANREB team.

A key element of the successful beam delivery and the final piece to be commissioned in the CANREB puzzle was the electron beam ion source (EBIS) – a special device for enhancing the electrical charge ("charge-breeding") of isotopes.  It was developed in collaboration with researchers at the Max Planck Institute für Kernphysik in Heidelberg, Germany.

“I am proud to be a part of this exciting project,” says Saint Mary’s University Ph.D. student Mathieu Cavenaile who is working at TRIUMF on studying charge breeding of rare isotopes with the EBIS. “It is a tremendous opportunity to be working at TRIUMF with the highly skilled team.”

"We were particularly happy to record the successful function of the EBIS in terms of charge-breeding a high-purity radioactive isotope beam," said Friedhelm Ames, CANREB project coordinator, TRIUMF Scientist and Adjunct Faculty of Saint Mary’s University. "This was the first real test of the full system using a radioactive beam similar to those that we expect to be soon delivering to ISAC science experiments: a charge-bred, intense beam with very low levels of impurities. CANREB's beam delivery system functioned as expected, which is a tremendous achievement for the many hard-working teams that have contributed to its deployment."

“The CANREB project recognizes that the universities are integral partners to TRIUMF,” says Malcolm Butler, Vice President Academic and Research, Saint Mary’s University. “It has showcased TRIUMF’s role as a national laboratory in supporting opportunities for researchers from universities with good ideas to lead and bring exciting discoveries out from the lab.”

“This success is a testament to the people in the team and the broader TRIUMF community,” says Jonathan Bagger, Director of TRIUMF. “Completion of the CANREB facility represents an essential step towards building the TRIUMF of the future.”

“It is a fantastic to see the CANREB infrastructure come together, a great achievement of the whole team,” says Reiner Kruecken, Deputy Director of Research at TRIUMF. “We can now really start exploiting this innovative infrastructure for exciting science and I am happy to be a part of that myself.”

The inaugural beam of copper-59, originated in TRIUMF's ISAC target station and was the first radioactive beam to undergo charge breeding with CANREB and be post accelerated through to ISAC-II. At the IRIS experiment a snapshot of the beam was seen through the lens of energy deposited in a gas-filled detector.  In nature, copper-59 is among the many radioactive isotopes whose reactions power astrophysical phenomena like X-ray bursts and could potentially contribute to the creation of some heavy elements. Using such beams at TRIUMF, researchers directly or indirectly such processes in the laboratory to gain insight on nature’s working.

This has been a remarkable achievement, especially during this globally challenging year with the pandemic, further showcasing the well-coordinated capacity of the CANREB team. As a tough year ended with a happy note of success, the team is looking forward to gearing up on further advancement of the project.

The CANREB project is thankful for research funding from the Canada Foundation for Innovation, the Nova Scotia Research and Innovation Trust, the Manitoba Research and Innovation Fund. It was also supported by TRIUMF's commercialization arm, TRIUMF Innovations and TRIUMF.

SMU researchers look at impact of COVID-19 on communities in Nova Scotia

A glimpse at the report’s title page.

A glimpse at the report’s title page.

A new study from a Saint Mary’s University-based research team into the impact of the COVID-19 pandemic on Nova Scotia’s communities was released today, Tuesday, Dec. 22, 2020. 

“What this research shows is communities coming together to help each other during a time of need,” says Dr. Tony Charles, a professor at Saint Mary’s University and the director of the Community Conservation Research Network. “The study reinforces what we already know about our communities, that they are resilient and can find community-based solutions to many problems. And for larger problems, they know the solutions needed but may need outside assistance to enact them.” 

When the pandemic came to Nova Scotia, Dr. Charles and his team were already looking at Nova Scotian communities, the issues they are facing, and their plans for the future. For each of 50 communities, they spoke to individuals in the community as well as elected municipal officials. When the pandemic appeared in 2020, the team decided to try to learn more about COVID-19 impacts and responses in communities.  

“We heard from people how very fortunate they felt to live in places that nourished them in so many ways – communities that rallied by reaching out and checking on one another, and supporting those who were more vulnerable,” adds Libby Dean, one of the researchers on the team.  

The study showed that all communities felt at least some impacts of the pandemic on their economic activities and social well-being. Sixty-seven percent of communities said they faced at least some moderate economic implications. Seventy-seven percent said there were social impacts, with 42 percent of communities feeling extremely affected by social and economic impacts. Environmental impacts of the pandemic ranged widely, with about a third of communities seeing little or no impact, a third noticing a low or modest impact, and one-third feeling environmental impacts were moderate to extreme.  

Of social impacts, the top ones identified were employment (listed by 58 percent of respondents), social and recreational activities (54 percent) and schools/schooling (50 percent). Of the top three impacts of the pandemic on economic sectors, most affected was the tourism industry (61 percent of respondents), followed by education/research (48 percent) and retail activities (39 percent). 

“The work of Dr. Charles and his team exemplifies one of the key pillars of research at Saint Mary’s University—working with our local communities to provide expert advice to address regional and global challenges,” says Dr. Adam J. Sarty, associate vice-president, Research and dean, Faculty of Graduate Studies and Research. 

“One thing that was clear from the survey was the importance of community-based groups to facilitate community solutions and responses,” says Dr. Charles. “Some of the themes noted in responses include access to services, financial aid, social connections, food security and volunteerism. In many cases, these responses were recognized as already an inherent part of the way of life in their community.”  

The community-based responses included supporting various services no longer as easily accessible, such as groceries and water, and dealing with concerns around food security and access, specifically for children and seniors. Communities also took action to address the need for social connections, such as through virtual religious services, take-out community dinners, and support for regional food banks and local community halls.  

Among the highlighted needs that communities require support to address was access to technology and, specifically, the internet. Much of what is being done now regarding education, recreation, arts, and even food services require robust and consistent internet access, which is a challenge in many -communities across the province.  

“Despite the uncertainty and the challenges, that sense of community is a strength for Nova Scotia,” says Dr. Charles. “While the forecast is not clear, strong communities help to weather all storms.”  

The research survey summary, Nova Scotian Communities & COVID-19: Challenges and resilience, was prepared by Dr. Tony Charles, Larissa Sweeney, Libby Dean, and Rebecca Zimmerman. For more information about the survey or to read the summary report, click here.

Project title: The Feasibility of a Program for the Prevention of Childhood Sexual Abuse.

Project description: Childhood sexual abuse (CSA) is a universal public health problem impacting 18% of girls and 8% of boys worldwide. Children are overrepresented as victims of sexual abuse, as 56% of police-reported sexual assaults in Nova Scotia involved victims under 18. Rates of sexual abuse in Nova Scotia are above the national Canadian average. CSA contributes to a significant disease burden, as it connects to a wide range of adverse mental and physical health outcomes. Effective prevention programs could stop CSA from occurring in the first place and prevent adverse health outcomes. In Nova Scotia, a significant gap in prevention programming is delivering comprehensive mental health services to individuals who may be at risk of CSA perpetration. Previous research has suggested that there are individuals who have not offended but struggle to stay offence free and experience mental health challenges. Through her research, Dr. Skye Stephens and the team aim to enhance capacity to provide CSA prevention programming in Nova Scotia by exploring development barriers. Knowledge gained during this study will lay the groundwork for developing and evaluating a prevention program that could reduce the occurrence of CSA and associated adverse health outcomes. Overall, the project could increase the health and safety of Nova Scotians by proactively addressing risk factors for CSA perpetration.

Congratulations to Emily Veinot, the winner of the 2020 Montreal Women’s Memorial Scholarship at Saint Mary’s University. Typically this award is presented at a ceremony on campus to observe the National Day of Remembrance and Action on Violence against Women.

Awarded each year to a female Engineering student, the scholarship honours the memory of the 14 women who were killed on December 6, 1989 at the École Polytechnique, the engineering school at the Université de Montréal. At the time it was the deadliest shooting in Canada, and gunman killed only women in the anti-feminist attack.

“As a woman in engineering but also as a Francophone,
I believe it is extremely important that we remember and honor the lives and goals of the women who were lost on that day,” said Emily.

“This award is an important reminder of the vital role that women play in scientific fields, and that there is still work to be done to reach the goal of gender equality in all disciplines,” said Dr. Lori Francis, Dean of Science at Saint Mary’s.

“Congratulations Emily on achieving this honour, your enthusiasm for engineering is inspirational, and I’m so proud that your hard work has paid off.”

Emily grew up in the Acadian community of Clare on the south-western tip of Nova Scotia and attended École Secondaire de Clare. She was athletic, playing soccer and track and field, and was very interested in environmental work, doing a volunteer study with a teacher and professor from the University of Saskatchewan, looking at human infrastructure influences on wildlife.

With a diesel mechanic father who taught her how to how to change tires and the oil in her car, Emily grew up around cars, and says she has always found mechanical and technological systems complicated and exciting.

“I’ve been around machinery my whole life. That sparked my passion for problem-solving and led me to pursue a career in mechanical engineering,” she said.

“My parents are proud,” she said. “If I was ready to do it, they were ready to support me.”

Now in her second year of study, Emily has an impressive 4.04 GPA. She has won a number of academic awards and bursaries, including a renewable entrance scholarship to Saint Mary’s, the Dr. Robert and Suzanne Van Den Hoogen Bursary, and a Nova Scotia Future Engineers Award.

“I always loved math and physics and design…calculus is a good time for me,” she laughed. My first year I really loved it, and during Design I we built boats and I thought that was so cool… I thought “I’m doing mechanical, that’s so fun.’”

Along with her studies, Emily is a Teaching Assistant for the Design I class. She is a member of the Canadian Federation of Engineering Students and the Atlantic Council of Engineering Students. As the bilingualism commissioner for the Atlantic Council of Engineering students, she provides French representation so it’s more linguistically diverse, and appreciates learning from her colleagues, most of whom are in their fourth year of study.

Next year she plans to attend Dalhousie University to complete her degree in Mechanical Engineering, and has applied to the co-op program to further develop her professional skills.

Emily says that while she’s happy to have been born at a time with a lot more gender equality, “it’s still an uphill battle, and there’s still a lot of underrepresentation of women in sciences and engineering. I think a lot of women are intimidated and talked out of it, and I think that’s so unfortunate. It’s never going to change if we don’t make the change.”

Saint Mary’s University is pleased to announce that Dr. Linda Campbell has won the Professional of Distinction award at the 18th annual Discovery Awards, held virtually on November 26, 2020.

Dr. Campbell, a Professor and senior research fellow in Environmental Science at Saint Mary’s University, has risen to the top of her field in environmental research, conducting and coordinating research groups across four continents. Her research and teaching at SMU focus on contaminants in the environment, as well as on sustainability and resilience issues with emphasis on aquatic ecosystems and water resources.

“Dr. Campbell is most certainly a professional, and person, of distinction. Dr. Campbell is recognized as a leader in environmental science research and is known as a scientist whose work increases our understanding of the impact of humans on the natural world,” said Dr. Lori Francis, Dean of Science at Saint Mary’s. “Her remediation work illustrates her drive to use new approaches to remedy historic contamination problems.”

“We here at SMU are proud of the work that she does and so very impressed by her desire to share her knowledge with the many students she has mentored.”

Her leadership was recognized early in her career; she received the W.B. Pearson medal for her PhD research, and building on this, her early career accomplishments were rewarded with a Canada Research Chair and a Canada’s Top 40 under 40 award in 2009. She is the recipient of over $10 million in funding for research, and despite working in environmental remediation, which often involves non-peer reviewed work, she has authored over 75 papers, given 150+ presentations around the world, and has supervised more than 20 graduate theses, and 30 undergraduate theses/projects. 

Within the university community she has served on Senate and is currently on the Board of Governors at Saint Mary’s University while also serving as a Trustee of Gallaudet University in Washington DC. This experience builds on her three terms as a Board member of the Canada Hearing Society from 2006-17. These accomplishments clearly demonstrate her leadership is sought at all levels, from local to international.

Dr. Campbell and her team at the Dynamic Ecology and Environmental Health Research (DEEHR) Group provide expertise and technological infrastructure to the study of contaminants in the aquatic environment. Her research extends to aquatic food webs, invasive species, terrestrial wildlife and human consumers of aquatic food.

As a researcher, she is shaping a new path for the study of environmental contamination in Nova Scotia. Her more recent work has uncovered new vectors for human-aquatic ecosystem interrelationships.

Along with her significant contributions to the scientific world, Dr. Campbell, who has been Deaf since birth and communicates in American Sign Language (ASL), has spent hours building awareness of accessibility in society. She has received a Nova Scotia Human Rights Award, as well as the Mel Hebb Hourglass Action Award as part of the Bill-59 Community Alliance. She has also worked closely with ASL-English interpreters to develop collaborative scientific and academic interpreting.

Successful in breaking ground in media accessibility, Dr. Campbell has worked with arts communities to introduce environmental issues to new audiences. In 2016 she led the development of an ASL movie detailing the impact of the Halifax Explosion on the children and staff at the Halifax School for the Deaf.  

Dr. Campbell has demonstrated time and again, that situations many would consider obstacles, can in fact be moments of opportunity. She is a role model whose passion, values, commitment to community, selflessness, and ability to overcome obstacles make her an invaluable asset to Saint Mary’s community, and Nova Scotia.

The Discovery Awards celebrate the outstanding achievement of scientists and innovators in Nova Scotia. Along with the Professional of Distinction category, awards were presented for Emerging Professional, Innovation, Science Champion, a Youth award, and Hall of Fame.
