General Information

I am an Assistant Professor in the Department of Mathematics at San Jose State University. Previously, I was a Van Vleck Visiting Assistant Professor and Research Associate at the University of Wisconsin-Madison (2012-2015). I obtained my Ph.D. from the University of Waterloo in 2011 and M.Sc. from the University of Guelph in 2006.

I was recently featured in the Course Hero Best Lessons Series. You can find my article on innovations and teaching strategies for the course Math 133A here.


  • Mathematical biology, dynamical systems, stochastic processes
  • Enzymatic pathways, signal transduction, genetic networks, etc.

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 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.
