He currently is a visiting scientist at the University of Guelph.

In the public, Jason is better known as The Germ Guy, and regularly offers his at times unconventional perspective on science in the media. Jason has written two books, The Germ Code, which was shortlisted as Science Book of The Year (2014) and The Germ Files, which spent several weeks on the national bestseller list.
