He is a member of the Debris Flow Association, member of the Standing Group on Glacier and Permafrost Hazards in Mountains (GAPHAZ), IACS, member of the Glacier Ice Thickness Estimation working group (IACS). Currently Dmitry Petrakov is lecturer of Glaciology and Debris Flow in Moscow State University, Faculty of Geography. He is supervisor of field courses in Glaciology for 2nd year students. Ongoing research projects are related to glacier change and hazards driven by glacier melting.
