I'm a freelance journalist, author, and broadcaster specializing in science stories. My latest book, The Science of Shakespeare, was published in April 2014 by St. Martin's Press in the U.S. and by Goose Lane in Canada. My previous books are In Search of Time and Universe on a T-Shirt.

My writing credits include Smithsonian, New Scientist, the Globe and Mail, The Walrus, Astronomy, Sky & Telescope, and many other newspapers, magazines, and websites. I've also written and produced dozens of radio documentaries, primarily for the CBC Radio program Ideas. Several of these documentaries have won prestigious international awards.

I co-host a podcast called BookLab with science journalist Amanda Gefter. The podcast reviews the latest in popular science books.

I'm also an avid amateur photographer. Some of my work (including science-related images and some astrophotography) can be seen on my Flickr account.

During the 2011/12 academic year I was a Knight Science Journalism Fellow at MIT. I live in Toronto, Canada.
