Current Fellow

Dr. Sophie Monnier-Serov was born in France where she attended medical school and did a general medicine residency before practicing as an attending in Pediatric Emergency Medicine in the Lyon area.  She then moved to the jungles of Loyalty Islands in the South Pacific, working as a physician with very limited resources. Dr. Monnier-Serov developed a strong interest in Disaster Medicine while working in the Loyalty Islands, as she dealt with inter-tribal conflicts which led to dozens of gunshot victims and four deaths. She was also one of the two medical providers on the Island during the tropical cyclone Vania, making transfer to the main Island of New Caledonia impossible for several days. Dr. Monnier-Serov then moved to the USA and completed her University of Massachusetts Emergency Medicine residency.  Beginning July 2018, she started her UMass Disaster Medicine & Emergency Management Fellowship.  Her main interest is International Disaster Medical response. When she is not working, Sophie enjoys spending her free time with her husband and going back home to France to visit her family, and likes to travel. She enjoys cooking and is always ready to try to new food!
