Alexander Osadchiev

Education:

2009 M.Sc. in Mathematics, Moscow State University, Russia
2014 Ph.D. in Mathematics and Physics, Shirshov Oceanology Institute, Russia

Research interests:

Alexander research is focused on land-ocean interactions with special emphasis on river plumes and associated transport of terrigenous material, nutrients, and pollutants. My principal goal is to improve our understanding of the underlying dynamics of these processes and their influence on coastal ecosystems. My research is based on statistical analysis of in situ and satellite data as well as numerical modeling using Lagrangian and Eulerian ocean models
