Alexandre Arkilanian explores how the precise timing of salmon death sustains ecosystems, showing that even endings have perfect purpose.

Where are you from?

I grew up in Montreal, Quebec, but my roots are Armenian—my family came to Egypt and Syria as refugees during the genocide before my parents immigrated to Canada.

Newfoundland and Labrador feels like a place of resilient people, many of whom have faced hardship—something that resonates with my own family’s history. I admire the way Newfoundlanders and Labradorians find joy in life’s small moments. I also love a feed of fries with dressing and gravy. I might say I prefer it to poutine but that goes against my Montreal programming.

What do you enjoy doing for fun?

One of my favourite things to do these days is a deep dive on Wikipedia. I find it really easy to lose myself in their cross-linked articles learning about anything from history to science to linguistics. I enjoy spending time outdoors—especially near rivers or coastlines—which ties in nicely with my research interests but also helps me relax and recharge. I also like cooking, exploring new music, and playing an occasional video game when I want to unplug. I don’t ever really stick to one hobby though, I’m more of a hobby collector.

Why did you decide to pursue a graduate degree?

I decided to pursue a graduate degree because, during my undergraduate studies, I was deeply inspired by the graduate students I met. They were not only intelligent and driven, but also inclusive and generous with their knowledge. There are two experiences that stood out for me. 

I remember my first lab meeting at the Redpath Natural History Museum at McGill—it was a grand, ornate room filled with about 20 graduate students and a few professors. I was both intimidated and excited to hear their thoughts on the paper we were discussing. But what struck me most was how openly ideas were shared, including mine, even though I was just starting out. That experience—of being welcomed into a space where intellectual exchange and curiosity were encouraged—sparked my love of research.

That love only deepened when I lived and worked for a few months in the forests of Mont Saint-Hilaire with a postdoc, Vincent, and a graduate student, Marie-Pier. Both were pivotal in my decision to continue in academia. Vincent showed me that you can be successful in research and still lead a balanced, joyful life—something I hadn’t seen modeled much during my undergrad. Marie-Pier, on the other hand, inspired me through her infectious excitement about her work. She studied tiny aquatic organisms like Daphnia and Bosmina, and I will always remember her joy as she called me over to the microscope to see a particularly pudgy Bosmina she had just found. That kind of passion was contagious—and unforgettable.

Why did you choose Memorial University for your graduate studies?

I chose Memorial University primarily for my supervisor Dr. Shawn Leroux but also for the opportunity to live in such a stunning province with easy access to inspiring natural landscapes. Shawn is one of a few experts in the type of mathematical methods I use in my research. Besides that, Shawn is also highly supportive of my work and my career aspirations.

What is your research/thesis about? How do you describe your research to a general audience with no background in the field?

Broadly, my research involves decomposition in seasonal ecosystems. I’m interested in large pulses of decomposing organic matter and their role in providing nutrition in an ecosystem. For example, annually, thousands of salmon migrate to small rivers from the ocean where they spawn and many die. This provides an essential form of nutrition for plants, fish, insects, and birds in and around those streams. The essential nature of these carcasses is even more likely when we consider salmon spawning happens around the same time each year, in October and November in Newfoundland and Labrador, before the harshness of winter arrives and food availability drops to extremely low levels. As seasonality changes, my research looks to better clarify when and how these carcasses can help sustain populations of animals and plants. For example, if seasons change to the extent that salmon are arriving in the middle of the summer, the nutrients derived from their carcasses are not likely to impact winter survival.

As climate change continues to reshape our environment, understanding the importance of timed events like salmon carcass arrival will be essential for effective conservation strategies. Much like how we, as humans, find meaning in the cycles of life and death when we lose loved ones, this research highlights the intricate role that death plays in sustaining life across ecosystems. By understanding these cycles, we can better appreciate the delicate balance between life’s end and its role in ensuring the survival of others, especially in a world changing so rapidly.

How would you describe your experience as a graduate student at Memorial?

So far, so good! I feel fortunate to be surrounded by a supportive and collaborative group of peers, which I believe is one of the most important elements of success in graduate school. My department also has a strong culture of collegiality, with many professors who are not only knowledgeable but also approachable and encouraging. It’s been a good environment for growing as a researcher and building lasting academic relationships.

What scholarships or awards have you received?

I am happy to say that I have received the Dr. Leslie Tuck-Avian Ecology Award and the Dr. Allan R. Stein Graduate Scholarship in Science.

Have you faced any challenges in life that you’ve overcome to pursue graduate studies?

Graduate studies are a demanding path, and I think most of us face challenges that test our commitment along the way. For me, there have been times when I seriously considered stepping away—due to financial strain, health concerns, or family responsibilities. Graduate school requires a sustained effort over many years, and the reality is that it often comes with limited financial support. It’s hard to maintain balance when there’s little room for things like travel or even going out for a meal with friends. That kind of constant sacrifice can wear on you, and at times, I’ve felt pulled toward the idea of an easier or more stable life.

But despite those moments, I’ve stayed committed—because I genuinely care about the work I’m doing, and I believe it can make a difference. That voice of doubt still exists, but it’s quieter now, and I’ve learned to navigate those thoughts with more confidence and clarity.

What career path are you interested in pursuing after graduation?

I am hoping for a career as a university researcher where I can teach and mentor students while also contributing to research. I find a lot of meaning in the combination of research and education. Ho ever, I recognize this is a highly competitive field and I’m open to other research opportunities like federal government scientist positions or positions within environmental NGOs.

What advice would you give to current or future graduate students?

I have a lot of advice I’d love to share, but I’ll stick to three key points that I’ve found especially useful. First, remember that you are not just a student—you’re an asset. Your supervisor didn’t bring you into their lab out of charity. They see your potential and value your contributions, including research they may co-author. Don’t lose sight of your worth in that relationship. Graduate school may not pay well, so make sure you’re gaining in other meaningful ways—whether through skills, mentorship, authorship, or alignment with your long-term goals.

Second, and you’ve probably heard this before, but it bears repeating—ask for help and ask often. Sometimes, just the act of forming a question helps clarify your thinking. And even if the answer isn’t what you were looking for, you’re contributing to a culture of openness, collaboration, and mutual learning. Graduate school can be isolating, and reaching out strengthens your connection to others in your academic community.

Finally, learn the power of saying no. You’ll be asked to take on all kinds of responsibilities—many of which aren’t directly related to your research. It’s okay to protect your time and say no to opportunities that don’t serve you. Whether you’re already stretched thin or simply want to leave space for more aligned work, your time and energy are valuable—and finite.

Anything else you would like to share?

I would just like to thank the dozens of inspiring and kind people I’ve had the fortune of meeting throughout this journey – you all continue to inspire and push me. I am comforted by the fact that I have made so many excellent friends and colleagues. Like with any job it is the people that make it worth showing up every day.
