I’m a freelance journalist, author, and broadcaster specializing in science stories. I’ve written three books: The Science of Shakespeare, In Search of Time, and Universe on a T-Shirt.

My writing credits include Undark, Quanta, Nautilus, Smithsonian, Discover, New Scientist, Scientific American, the Globe and Mail, The Walrus, Astronomy, Sky & Telescope, NBCnews.com, Slate, 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 popular science books.

As well, I’ve worked as a sessional instructor at the University of Toronto, developing and teaching a course for undergraduates called “Science and Literature,” through the Institute for the History and Philosophy of Science and Technology (IHPST).  (I earned an MA from the IHPST in 2014.)

I’m the recipient of the 2019 Fleming Medal for Excellence in Science Communication from the Royal Canadian Institute for Science.

In 2019 I was the Science Communicator in Residence at York University in Toronto. In fall 2018 I was an Ingenuity Fellow at the University of New South Wales in Sydney, Australia. And during the 2011/12 academic year I was a Knight Science Journalism Fellow at MIT.

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 (though I haven’t updated it in a while – if you’re into photography, follow me on Instagram).

Asteroid 20039 Danfalk is named after me. 🙂  (It’s very faint – but, here is a photograph of it!)

I live in Toronto, Canada.

I’m on BlueSky as @danfalk.bsky.social and on Instagram and Threads as @danfalkscience.
