Applied Mathematician wins Governor General’s Doctoral Gold Medal in 2017

Stilianos Louca is the recipient of this year’s Governor General’s Gold Medal, awarded annually to the doctoral student who has achieved the most outstanding academic record at UBC.

Medals are presented on behalf of the Governor General of Canada by participating educational institutions, along with a personalized certificate by the Governor General. Although there is no monetary component to the award, the Gold Medal is highly prestigious in that only one is awarded for more than 500 doctoral graduates each year.

Stilianos received his PhD in Mathematics in November 2016 and is currently a postdoctoral fellow at the Biodiversity Research Centre. We sat down with him in May to find out a little bit about his doctoral research, his career path and what drew him to UBC.


What defines me as a scientist is not the methods I use but the types of questions I ask.

Stilianos’ research focuses on the role of microorganisms in biogeochemical cycling in the environment. He uses mathematical tools, surveys, and experiments to look past the cell wall and into the genetic content of microorganisms, in order to determine how these microorganisms impact the biochemistry of and respond to environmental changes within their communities. People try to design efficient microbial communities for industrial process such as biofuel production, but because there is intrinsic change, it is hard to maintain a stable set of species. By developing an understanding of the essence of these communities, scientists could better understand how to manipulate them and make them do what they want them to do. The results of this research could show that perhaps genes are not some mechanism that evolution invented for us as organisms to propagate and survive, but are in fact agents with their own agenda and role in the ecosystem.

You range into all areas of science, do you have an allegiance to one?

“A lot of the tools I’ve acquired over time, especially from physics and math, have turned out to be extremely useful for answering questions in biology, so what defines me as a scientist is not the methods I use but the types of questions I ask. I try generally to separate the two. First I ask the question, and then I think about the best way to address that question, and that has, over the years, involved mathematical modeling and my knowledge from physics and bioinformatics and molecular techniques in the lab. “

Now that you’re a postdoc, how do you envision your career going forward?

“I would like to keep doing science and preferably get paid for it. Which in practice means I do want to eventually end up as a researcher somewhere, ideally with a professorship. Keep doing science driven by my own fundamental questions. Personally, I think back very fondly of all of my time so far in terms of the different revelations I’ve had for myself, these a-ha moments as they might call it. I think it was all worth it.”

How do you achieve a good work-life balance?

“You just have to do what you feel in the moment and don’t feel pressured. If you’re captivated by your project then just work on it and don’t convince yourself that you need to somehow finish by 5 o’clock. Just do as you feel. There is no single optimal work-life balance, apart from at the individual level, you just have to figure it out for yourself and perhaps with your partner or family.

Why did you choose to come to British Columbia and study at UBC?

“Well, to be frank, the mountains. A couple of years before I came to UBC, I discovered hiking for myself. I really like to go to backcountry places for long hikes. That was the first criteria – am I going to have the opportunity to pursue that passion?”

If you had one thing to say to people that are new to UBC what would it be?

“I think from a science point of view, be bold, trust your own intuition and your own questions, and if something is really interesting to you then just think about it more. You might arrive at a new interesting idea. Just keep an eye open for your passion.”
