Science grads make SMU history with four-way Gold Medal tie

In a first in Saint Mary’s University history, four Spring graduates tied for the Bachelor of Science Undergraduate Gold Medal, earning the top GPA marks in the program. Abby Brouwer, Sumayyah Chotoye, Jaylynn Skeete and Allison Vandaele received their medals at the recent May convocation ceremony. Typically, only one undergraduate student in each faculty receives this award.

“We could have approached this four-way tie as a problem, but instead we celebrate the outstanding performance of these hardworking graduates whose commitment and perseverance are an inspiration to us all,” said Interim Vice-President, Academic and Research Madine VanderPlaat at the May 18 ceremony.

All four graduates received numerous awards and scholarships during their time at Saint Mary’s. Brouwer, from Hammonds Plains, NS, majored in Biology and plans to attend dental school. Chotoye, from Port Louis, Mauritius, majored in chemistry (honours) with a minor in French and is currently in the Master of Science, Applied Science program at Saint Mary’s. Skeete, from Dartmouth, NS, majored in psychology (honours) and will be entering a Masters/PhD program in clinical psychology. Vandaele, from Montague, PEI, majored in psychology (honours).

Congratulations, graduates!

Meet your Valedictorian: Natania Blair BSc'23

Natania Blair BSc’23

As an international student, Natania Blair expected her environment to change when she arrived in Halifax from rural Jamaica, but she couldn’t have known then exactly how much it would change. Natania and her cohort worked towards their degrees through the COVID-19 pandemic, transitioning to online learning with many unable to return home. Natania was also a residence assistant, dedicated to helping students through this difficult time.  

An impressive list of extracurricular activities and volunteer work never stopped her from excelling at her studies, she worked hard until the last term—taking six classes in her final two terms during the 2022-23 academic year, an impressive feat.

Natania is proud to have family attending convocation, including her younger sister, a Saint Mary’s student taking biology in her big sister’s footsteps. She is currently working in Halifax and is planning to pursue permanent residency and medical school.

Q&A with Natania Blair

Where is your hometown?: My hometown is in rural Jamaica. A vibrant community, rich in culture, called May Pen, in the parish of Clarendon.

What’s your major?: I’m graduating with a Bachelor of Science with a major in Biology.

What was your favourite class?: Global Change with Professor John Calder. It was a very eye-opening course. I also enjoyed GEOL 1203  Earth History: Atlantic Canada Perspective with Professor Randolph Corney.

Is there an instructor who had a big impact on you?: So many professors had positive impacts on me. Some are Dr. Andrew Hare, Professor Caitlin Cunningham and Dr. Anne Dalziel. They were excellent motivators and role models.

Why did you choose Saint Mary’s University? An international recruiter named Lauren Cullen met with me in Jamaica and told me all about SMU. She got me so excited to be a Husky SMUdent!

What activities were you involved with at Saint Mary’s?: My most impactful activity would be my role as a Residence Assistant. Thanks to Kati Kilfoil and her team, I garnered important life skills and valuable experiences throughout my three years of being an RA. I was also part of the Executive Team as the Public Relations Officer of the Caribbean Society in my fourth year.

What was your favourite space on campus?: My favourite space on campus is the SMU Gym. I was on the Cheerleading team in my first year, and we would practice in the SMU gym. Since then, I’ve made going to the gym a priority.

Do you currently volunteer with any organizations?: I was previously a SAGA Volunteer (Students Acting for Global Awareness). I took on the role of mentor and welcomed students who were new to the SMU family.

Did you receive any awards or recognition from the university or other organizations during your time as a student here?: I received an award for showing resilience as a Residence Assistant during the COVID-19 pandemic, as well as an award for Outstanding Programming as an RA. I made the Dean’s List, which I am very proud of. Being Valedictorian for the Faculty of Science at this 2023 convocation is such an honour in itself. 

What advice would you give your younger self who was just starting university?: You are smarter than you think. Keep being that happy, positive, and optimistic girl despite any challenges you may face along the way. Don’t let anyone dim your light—if you are too bright for them, offer them some shades. And remember you can do all things through Christ who strengthens you.

What are your goals for the future?: I hope to continue my studies of the Sciences in pursuing my dream of becoming a Medical Doctor.

Three-Minute Thesis winner to represent Saint Mary’s at Eastern Regional competition

Shannon MacFarland, a first-year Master of Science student in Astronomy, won first place in the recent Three-Minute Thesis (3MT) competition at Saint Mary’s University. Her topic ‘How does a galaxy die? Determining the star formation history from a galaxy's colour’, also earned the People’s Choice award at the competition. MacFarland will compete in the Eastern Regionals in June.

In second place was Gabrielle Armstrong, Master of Science in Applied Science. Stephen Paterson, PhD in Applied Science, received an honourable mention.

Condensing a thesis—the result of months or even years of work—into three minutes is an impressive feat. Three-Minute Thesis (3MT) competitors are challenged to condense and communicate their work while still making it accessible to a non-expert audience—with the clock ticking. Hosted by the Faculty of Graduate Studies and Research, the annual 3MT event saw seven Saint Mary’s Masters students and PhD candidates explain their research with one static Powerpoint slide, no other props or aids. The participants spoke about a wide range of topics, showing the breadth of research and study at Saint Mary’s University.

Originally from White Rock, British Columbia, MacFarland completed her BSc at the University of British Columbia. She chose Saint Mary’s for her graduate studies because her supervisor, Dr. Marcin Sawicki, is part of CANUCS (The Canadian NIRISS Unbiased Cluster Survey). CANUCS has guaranteed observation time with the James Webb Space Telescope (JWST).

“It's very competitive right now to get time with such a new instrument, so I could not turn down an opportunity to work with JWST data within the first year of its operating time,” says MacFarland. “I'm very fascinated by the distant past and galaxy evolution. JWST is the perfect tool for looking far back into the universe, and Dr. Sawicki's group is full of experts and students that share that passion, so SMU seemed like a good fit.”

Shannon is wesring a white top and brown pants. She stands in front of a large screen depicting stars and galaxies.

Shannon MacFarland presents at 3MT

More about Shannon MacFarland’s research: The colour of a galaxy contains a large amount of information about what stage of life a galaxy is in. Broadly, we put galaxies into two categories: Blue galaxies are considered "alive" because the gas within them is being compressed to form new stars. Red galaxies are considered "dead" because there is little to no star formation within them. We also know that in the past, there were more blue galaxies than there are today. This indicates some process by which a galaxy's colour transitions from blue to red, and its star formation is suppressed or shut down. What I'm interested in is how quickly/slowly a galaxy transitions from blue to red, also known as a galaxy's star formation history. To do this I am using the most powerful telescope ever created, the James Webb Space Telescope. This research is important because we know from the diversity of galaxies that we see that all galaxies evolve differently. My work will aim to answer how all galaxies, like our own Milky Way, will eventually die.

Saint Mary’s joins TRIUMF, Canada's national particle accelerator centre

A large facility with machinery and containers

Meson Hall is TRIUMF’s first and largest research facility. Four storeys high with another four storeys below ground, the building houses the laboratory’s 520 MeV cyclotron – certified by the Guinness Book of World Records as the largest accelerator of its type in the world.

On March 6, 2023, Saint Mary’s University became a full member of TRIUMF, Canada's particle accelerator centre, joining a group of 21 universities across the country.

TRIUMF is a hub for discovery and innovation along with its partner institutions—solving problems, from the hunt for the smallest particles in our universe to advancing research that discovers the next generation of batteries or develops isotopes to diagnose and treat disease.

As a full member, Saint Mary’s will be empowered to participate in and lead the TRIUMF science program, including the laboratory’s vision-setting and its multifaceted and intersectional portfolio of collaborations and network opportunities.

“Saint Mary’s University is honoured to be enhancing our partnership with this renowned facility," says Dr. Adam Sarty, Associate Vice-President, Research. “By committing to now change our status to have full membership with TRIUMF, our professors and students will be ensured to maintain their access to sophisticated, isotope science and technology to innovate, inspire and educate. Working more fully within the TRIUMF family of member universities, we will achieve greater collaboration across communities and disciplines, from nuclear and particle physics to the life and material sciences.”

TRIUMF is one of the few subatomic research facilities in the world that specializes in using particle accelerators to produce extremely intense beams of isotopes. Particle accelerators use a combination of electric and magnetic fields to accelerate and guide streams of charged particles to relativistic velocities. 

In fact, TRIUMF is home to the world’s largest cyclotron, a special type of particle accelerator that accelerates particles up to 75% of the speed of light as they follow a spiral path through it. 

Particle accelerators are useful tools for science, medicine and business. For example, they can produce some of the most extreme conditions in the universe, allowing researchers to study how exotic, unstable isotopes form and break apart, as well as particles and molecules in their work. Some of these isotopes also have tremendous value for use in diagnostics scans for neurodegenerative diseases like Parkinson's and Alzheimer's, or even direct therapies for diseases like cancer. At TRIUMF, scientists from around the world use particle accelerators for particle and nuclear physics, life sciences and medical research, materials science, and more.

Saint Mary’s has long had a collaborative relationship with TRIUMF, and two years ago Saint Mary’s led a national project for rare isotope research at the facility. A team of scientists including SMU Principal Investigator Dr. Rituparna Kanungo achieved a major milestone, accelerating for the first time a radioactive isotope beam through the CANREB (CANadian Rare isotope facility with Electron Beam ion source) 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.


About TRIUMF

TRIUMF was founded in 1968 by Simon Fraser University, the University of British Columbia and the University of Victoria; it has expanded to include members across Canada. The science program has expanded from nuclear physics to a multidisciplinary effort that includes particle physics, molecular and materials science, and nuclear medicine. TRIUMF provides research infrastructure and tools that are too large and complex for a single university to build, operate, or maintain.

Located on the UBC campus, the houses almost 600 scientists, engineers, and staff performing research. A hub for discovery and innovation, the laboratory attracts almost 900 national and international users every year and provides advanced research facilities and opportunities to 150 students and postdoctoral fellows. In addition to the onsite program, TRIUMF serves as a key broker for Canada in global research in particle, nuclear, and accelerator physics.

Meet your Valedictorian: Anastasia Sagel BSc’23, Faculty of Science

 Anastasia Sagel first came to Halifax to study at the Language Centre at Saint Mary’s; she liked the university so much that she stayed for her undergraduate degree in psychology. Immersing herself in the cheerleading community on campus, Anastasia became the captain of the team and would love to share her passion for the sport with students when she returns home to Germany. She plans to pursue a graduate degree in psychology with the goal of working with children who have PTSD. Anastasia is proud to be the Faculty of Science valedictorian with her family who are visiting from Germany for the big event. Congratulations! 

Preferred name: Anastasia

Program: Bachelor of Science, Honors Psychology

Previous education: St. Kaspar

Hometown: Bad Driburg, Germany

Why did you choose Saint Mary’s University?
I chose Saint Mary’s because of the percentage of international students.

How did you get involved in the SMU Community?

I was on the team for four years as a base and captain for three years.

Did you live and/or work on campus? 
For the first two years, I lived on campus.

What was your favourite class? 
My favourite class was Psychotherapy II with Dr. Skye Stephens.

What was your thesis title and description? Why did this research appeal to you?
The title was, “Does switching between languages have an impact on emotion regulation?” This study investigated how emotion regulation might change when bilingual individuals switch between languages. We recruited self-identified bilingual people (N=129) via social media and the Sona system. After imagining themselves in two different scenarios, we invited them to respond to a cognitive emotion regulation questionnaire. The scenarios were identical, except that one was supposed to take place in their native language and the other in their second language. I chose this topic because I am multilingual myself and I wanted to see how that makes me different from others.

Which instructor had the biggest impact on you? 

I had three: Dr. Jim Cameron, who was my thesis supervisor, who really believed in me and made writing my thesis fun; Dr. Skye Stephens, who taught so passionately, which assured me that I had chosen the right profession for me; and Dr. Andrés Arteaga, who was my main prof for my Spanish minor and the only one that I had from first year till my last and who only ever saw the best in me.

Anastasia Sagel’s cheerleading team

Do you have a favourite space on campus?
The Atrium, which is the best place to study, and the gym.
Looking back, what was your favourite SMU memory?
My favourite SMU memories were when I presented my thesis at our psychology conference, and winning competitions with my team.
What will you miss about Saint Mary’s?

I will miss the feeling of sitting in the Atrium meeting friends and studying for class.
What are your goals for the future? How did Saint Mary’s help set you on this path?

I will be moving to Berlin to start my Master’s in clinical psychology at Sigmund Freud University. Saint Mary’s showed me that psychology is the right career choice for me and showed me that your past does not determine your future and that every semester is a new chance to improve yourself.

Did you or do you currently volunteer with any organizations?
I volunteered with our Cheerleading team at various organizations.

Did you receive any awards or recognition from the university or other organizations during your time as a student here?

I was placed on the Dean’s List three times.

Any other successes you’d like to share?

I am very proud that I will be graduating magna cum laude as well as winning every competition in our division with the Cheerleading team.

What advice would you give your younger self who was just starting university?

I would tell my younger self not to worry so much and enjoy the time more, rather than always focusing on what is next. Also that what is meant to be will be.

 

Saint Mary’s students research Sable Island horse skulls

Sable Island is a place of mystery and history, a remote island in the North Atlantic fabled for its sand dunes and shipwrecks, and almost impossible for the average person to access. But for naturalists and biologists, there is much to learn, especially from studying the wild horses who thrive there.  

On a November evening, dozens of Haligonians gathered in the McNally Theatre Auditorium to hear the latest Sable Island research and get up close to the skulls of these unique horses collected over 30 years by Zoe Lucas, President of the Sable Island Institute.  Katharyn Chadwick and Richard Orton, doctoral students at Saint Mary’s University, collaborated on the project with the Sable Island Institute, Nova Scotia Museum of Natural History and was possible due to funding from SMU Works. The project involved 716 skulls and more than 13,000 measurements and over 6000 photographs. Members of the public were invited to ​view​ the skulls on display, ask questions​,​ and even carefully touch the specimens. ​Two​ skull​s​ stood out​, one​ for ​a​​ ​large growth protruding from the upper jaw and ​the other for an ​odd deterioration​ and pitting of the​ lower jaw.  The researchers want to know if anyone can suggest what caused th​ese​ malformation​s; suggestions include a bone abscess or tumour, and a root canal abscess​.  

More importantly, why study this group of horses and their skulls for clues about their development,​ variation in skull morphology and age?​ Richard and Katharyn explain that ​​since the horses first arrived on Sable Island there have been numerous introductions of other horse breeds, to improve breeding stock, provide additional labour and produce foals for resale back on the mainland. This has likely led to a complex mixing of the population, with genetic work revealing traces of Morgan, Clydesdale, and Thoroughbred.​ Sable Island horses have been isolated for at least 50 years and it is common that island populations exhibit unique traits.

“However, we do not always understand the biological mechanisms underpinning such unique adaptations,” says Katharyn Chadwick. “ Therefore, a deeper understanding of the ​skull ​morphology might further our understanding of the evolution of the Sable Island horses​ and highlight any unusual morphologies unique to this population​​.”

One of the main aims of the project was to catalogue this unique collection, photographing each skull, estimating age, and noting gender unusual features, post-mortem/storage damage and injuries. Finally, thousands of bagged teeth were paired with the correct skulls.​​     ​​ 

​​​From the teeth, several well-described aging metrics commonly used in equine studies were recorded for each horse. Using data collected by Zoe Lucas on known age horses, the researchers hope to confirm the suitable use of these metrics for the Sable Island horses.​​     ​​ 

“Kate and Richard’s study of the horse skulls is an important contribution to the Sable Island Institute’s long-term research program. There is still much to be learned from the collection, and now we have a detailed inventory and preliminary data that will assist in planning follow-up work,” says Zoe Lucas. “This unique and extensive reference collection will enable the Institute to study variations within the Sable population. It will also provide a basis for comparisons with other groups and breeds of horses, as well as with Sable Island horses living on the Island decades from now. This project has been a very productive and encouraging collaboration, and the Sable Island Institute looks forward to further work with Saint Mary’s University and the Nova Scotia Museum.”

Both PhD candidates have travelled from other countries to pursue their studies at the Frasier Lab at Saint Mary’s University. In addition to their research project on the Sable Island horses, they will be addressing conservation concerns of the North Atlantic Right Whale using different genetic approaches. Specifically, Katharyn Chadwick’s thesis is centered on understanding how ship strikes and non-lethal entanglements lead to ​changes in ​gene​     ​​ expression​​     ​​ via epigenetic​ modifications, while Richard Orton is assessing the impact of genetic mutation on reproductive success in North Atlantic Right Whales. 

Celebrating excellence: Saint Mary’s faculty recognized for external research funding

Researchers at Saint Mary’s University continue to be recognized for their important work in their fields, securing over $11 million dollars in external funding in the form of research contracts, Canada Research Chair positions and tri-council grants, over the last 12 months.

A celebration to honour 90 researchers from faculties of Science, Arts, and the Sobey School of Business took place in the McNally Theatre Auditorium on November 10th. A few examples of how their research contributions will impact our communities include investigating healthcare resource planning for older adults, exploring how to retain international students in Atlantic Canada, and enhancing Canadian vaccination strategies using machine learning and business analytics.

Special recognition was given to Dr. Gavin Fridell, Tier 2 Canada Research Chair (CRC) in International Development Studies (2012 to 2022) and Dr. Kevin Kelloway, Tier 1 CRC in Occupational Health Psychology (2008 to 2022) for completing their CRC terms during their academic careers at Saint Mary’s University.

Our ecosystems will benefit from Saint Mary’s researchers that are implementing small-scale fisheries guidelines, conducting salt marsh restoration and community-based watershed monitoring. Other research is determining the future impacts of freezing and storing sperm to assist the endangered Inner Bay of Fundy Salmon population.

The quality of research happening here at Saint Mary’s University is something that we should all be proud of, congratulations again to the CRCs who recently completed their terms, and all of those that have been recognized.

 

Engineering students tour on-campus construction site

Saint Mary’s engineering students were invited to get an inside look at the Sobeys Inspiration Hub construction site early in November. The EllisDon construction team and Jillian MacMillan, Project Manager with Facilities Management, connected with the SMU engineering society to offer detailed tours, answer questions and inspire students.  

“This tour was an awesome opportunity,” says engineering student Oluwatomiwa Dotun-Olutola. “It’s great to see engineering work in progress and get to experience hands-on work.” 

In addition to getting a tour of the construction site, the students met with project managers from SMU and professionals from EllisDon who shared their experiences of working in the construction field and how they found themselves in these roles.  

“I have an engineering degree,” says MacMillian. “I would have loved to have the opportunity to take a tour through an active construction site to see what it was all about!”.

Researching microbial-terroir and its impacts on wine flavour 

A collaboration between Dr. Clarissa Sit’s chemistry lab and L’Acadie Vineyards is marrying Nova Scotia’s history of winemaking with modern chemistry. The research is exploring the effects micro-organisms have on the flavours of grapes in Nova Scotia’s vineyards. L’Acadie Vineyards owner Bruce Ewert was excited to partner with Dr. Sit to determine what unique fungi and bacteria contribute to the flavour profiles of wines produced at his award-winning, Annapolis Valley vineyard.

“This project came about because of one of the students in my research lab,” says Sit. “After attending a research seminar, we started looking at the micro-organisms in the soil and on the surface of grapes in Nova Scotia vineyards.”   

Sit’s research presented an opportunity for L’Acadie Vineyards. The first certified organic vineyard in the province and the first biocyclic vegan winery in North America, the family-owned business specializes in an array of organic natural wines. 

While conventional wines are frequently treated with sulfites to kill microbes, natural wines rely on native yeast from the fermentation process to do so. Microbes in the soil are splashed onto the grapes during irrigation and rain events. 

“The mixture of micro-organisms on the surface of the grapes adds flavour to the wine,” says Sit. “That’s what we’re curious about, and vineyard owners are equally curious. We want to see if there are differences in the year-to-year vintages depending on how microbes affect their flavour profiles.”

"Dr. Sit has been so supportive and encouraging. I never thought I would study wine yeasts and the complexities of natural winemaking. I love telling people I am getting a PhD in wine," says graduate student Lauren Grant, pictured above (far right).

In her research, Sit has compared soil samples from L’Acadie Vineyards with those from conventional vineyards to determine the difference between micro-organisms in the soil. These samples were brought back to the lab to isolate some of the strains for in-lab fermentation. 

“We’re adding some of those strains into sterile grape juice to see what chemical profiles they’re producing. We can analyze the strains we’ve been able to isolate to see what flavours each of the microbes are producing and create interesting new combinations.” 

While research is expected to continue for another three years, the project has the potential to grow depending on its findings, says Sit. 

“The focus will now be on the profiling and figuring out what aromatic compounds these microbes are producing and how vineyards can use them to create flavour while benefitting the environment.”

Helping the North Atlantic Right Whale rebound

Dr. Frasier speaking to students

At nearly 70 tonnes, the subjects of Dr. Timothy Frasier's research are massive examples of how quickly a species can progress to the brink of extinction. North Atlantic right whales are one of the most endangered large whales globally, with fewer than 400 in existence. While protection initiatives are in place, Dr. Frasier is concerned with the whale's low reproduction rate.   

Using genomic data, Dr. Frasier works to better understand what genetic factors limit the species' recovery. Early hypotheses suggest that low genetic variation and inbreeding could be possible factors. By determining the factors that limit reproductive success, conservation efforts can be more effective and efficient in saving the species from extinction.

"By working with colleagues and governments in Canada and the United States, we can move fairly quickly from research results to impacts on policy and procedures," says Dr. Timothy Frasier of the Faculty of Science. "Right whales are in a very precarious situation, and we need to identify how conservation actions can be changed to improve the chances for the species to recover." 

With $6 million in new funding, Dr. Frasier and his colleagues from Genome Atlantic and the New England Aquarium can continue their research into what factors limit the reproductive success of right whales. This work will help focus conservation efforts to save these beautiful mammals.

Did you know? Each year, our Faculty of Science and the Canadian Whale Institute host a 10-day Marine Mammal Summer Camp, where teens conduct hands-on marine research in the laboratory and off the coast of New Brunswick (pictured above).
