Brief Bio

Dr. Andrey Savtchenko received his M.S. in physics from Sofia University, Sofia, Bulgaria, in 1981, after which he received M.S. in radar remote sensing from the Bulgarian Academy of Sciences, Sofia, Bulgaria, in 1983. During his years at the Academy he built substantial expertise in Radar Oceanography, and in 1992 was awarded with research fellowship from the International Research and Exchange Board (IREX), United States Information Agency. In the fall of 1993, he was awarded a scholarship at the University of Delaware, from a grant from the US Department of Defense Office of Naval Research (ONR), and consequently enrolled in a Ph.D. program at the University of Delaware, College of Marine Studies, Delaware.

His research specialized in the area of non-linear air-sea interactions and sea surface radar returns. After his graduation in 1997, Dr. Savtchenko assumed Postdoctoral Associate position at the University of Miami, Rosenstiel School of Marine and Atmospheric Science, Department of Meteorology and Physical Oceanography, Miami, Florida. In this role, his research was oriented towards profiling of tropospheric winds, clouds, precipitation, and hurricanes.

Dr. Savtchenko joined NASA/GSFC in 2000, supporting Earth Observing System, and brought with him a broad knowledge in air-sea exchanges, remote sensing, boundary layer meteorology, advanced statistics, tutoring students and managing investigative teams. He is currently Principal Support Scientist with ADNET, on the SESDA 5 project, leading wide range of tasks at the Goddard DAAC, Code 619. He has been involved in providing science data analysis while supporting numerous missions: MODIS, AIRS, CloudSat, CALIPSO, OMI, MLS, TRMM, GPM, MERRA, and most recently OCO.

His current interests are primarily in atmospheric thermodynamics, physics of clouds and precipitation, boundary layer meteorology, and climate variability. In his work he is applying advanced statistical methods, such as empirical orthogonal functions, wavelet analysis, Hilbert transform, hypothesis and confidence tests.

Dr. Savtchenko is a member of AGU and AMS.
