Research Scientist, NASA Goddard Space Flight Center
Dr. Alexei Lyapustin received a M.S. from Moscow State University in physics in 1987 and a Ph.D. from the Space Research Institute in aerospace remote sensing in 1991. From 1997 to 2011, he was a research scientist at NASA Goddard Space Flight Center through USRA and later the University of Maryland Baltimore County. Alexei joined Goddard as a civil servant in 2011. Alexei's research interests focus on remote sensing of atmospheric aerosol and land surface environmental parameters (bidirectional reflectance and albedo; snow properties including grain size, albedo and sub-pixel snow fraction) from polar-orbiting and geostationary sensors, analysis of field campaign data, and 1D and 3D radiative transfer theory with gaseous absorption and polarization. He is the developer of the Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm for MODIS. Alexei is a member of MODIS, JPSS VIIRS and DSCOVR Science Teams, as well as a member of GeoCAPE aerosol working group.
