I am a physician, and recently returned from a mission in Dadaab, Kenya, the world’s largest and fastest growing refugee camp. When not in the field, I am assistant professor in emergency medicine at the University of Toronto, and an associate editor at the Open Access medical journal, Open Medicine. I am the author of the best-selling book “Six Months in Sudan”, which began as a blog detailing MSF’s work in the contested region of Abyei.
