Teaching (Fall 2017)

Student Research Opportunity (Spring 2018)

Funding is available for a student assistantship during Spring 2018 on the project “Stability and Model Reduction in Biochemical Reaction Networks.” To read about the project and how to apply, please read the Project Description. The deadline to apply is November 1!

This opportunity is made possible by the Central Research, Scholarship and Creative Activity (RSCA) Program through the Office of Research.


I was raised in a small farming community Southern Ontario just west of Toronto. My non-academic hobbies include playing baseball, running, playing guitar, writing short stories, and enjoying family time with my wife, Kaitlin, and twin boys, Mason and Austin. I am also known to frequent coffee shops and open mics. Despite my Canadian blood, I have never learned to skate.

My brother is Nathaniel Johnston, a fellow mathematician specializing in quantum information theory at Mount Allison University in Sackville, New Brunswick.
