Mirjam Guesgen

Freelance Science Writer

I am a freelance science writer currently based in Toronto, Canada, with a particular interest in animal welfare.

I love communicating complex, scientific ideas in an engaging, balanced, thought-out and informative way.


I am a freelance science journalist with an interest in stories that examine an issue from many angles: science, law, culture, psychology or philosophy.

My work has been published in The Globe and Mail, Motherboard, The Cut, Canadian Geographic, Aeon, Seeker, Maisonneuve, The Record, The New Zealand Herald, The New Zealand Listener and VetScript magazine. I also write for the YouTube channels SciShow and Hot Mess as well as my own dedicated science channel ScienceWrapNZ. My features on health issues in pug dogs and livestock diagnostic technology were front-cover stories. My article on animal facial expression has been shared worldwide, earning more than 150,000 reads.

Before I became a full-time writer, I received my PhD in Zoology from Massey University, New Zealand and went on to complete a Postdoctoral Fellowship at the University of Alberta, Canada. I have published nearly a dozen scientific publications ranging in topic from describing lamb facial expressions to how to measure emotion using motion capture technology.
