Since he was a teenager, Jason Tetro has called the laboratory his second home. His experience in microbiology and immunology has taken him into several fields including bloodborne, food and water pathogens; environmental microbiology; disinfection and antisepsis; and emerging pathogens such as SARS, avian flu, and Zika virus. 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. He has also co-edited, The Human Microbiome Handbook, which provides an academic perspective on the impact of microbes in human health. He lives in Toronto.
