My Books.

As an author with Penguin Random House Canada (Doubleday Canada) I have been fortunate to write two books on our relationship with microbes. You can order the books by clicking on the image.

My Work.

For nearly a decade, I've been working to increase public awareness of microbes and health. Most of my efforts come in the form of columns and blogs. Here you can find the most popular sources.

Huffington Post Canada

Each week, learn about the latest research in microbiology and how the information impacts each of our lives. In Huffington Post fashion, it is both interesting as well as informative.

Popular Science

What does the present knowledge tell us about our future? Check in each week to find out how recent research may one day change our lives.


I am a regular in Canadian and international media. You can usually find me on CBC Radio One and also Sirius XM. I've also been involved in the development of documentaries and short films. Keep an eye on the blog for more.

Awareness & Advocacy.

I am working with several organizations and institutions to raise the awareness of science and also to improve the climate for meaningful research.

More About Me..

Since I was a teenager, I have called the laboratory his second home. I started out in biochemistry but eventually found my home in microbiology and immunology. I have worked in several fields including bloodborne, food and water pathogens; environmental microbiology; disinfection and antisepsis; and emerging pathogens such as SARS, avian flu, and Zika virus. I'm proud to be a visiting scientist at the University of Guelph.

The Update Blog.

Keep up with what I am doing and thinking by reading the blog posts here.

Time for a New Look.

Now that the tour is over and I am embarking on several different routes, I've given the website a fine tune. I'll still be tinkering over the coming weeks but I hope you enjoy the new look and also keep up with my updates as they happen...
