Q&A with Dr. Jesse Popp

I study the abundance and distribution of critters and plants in ecosystems. I am particularly fascinated with fresh water and marine ecosystems. They are incredibly complex, incredibly diverse and the fact that they persist in the face of environmental change that's what really fascinates me.

I have always had a deep connection with nature and loved learning about it in my free time. After my undergraduate degree I wanted to become involved in environmental science, but I wasn’t sure about doing a thesis-based masters. Luckily, I found out about the Master of Environmental Science (MES) degree at the University of Guelph, which is a course based masters, but allows for some research if you are inclined to do so.
