Biography:
Dr. Alexei I. Lyapustinreceived an MS/BS in physics from Moscow State University in 1987, and Ph.D. in Aerospace Remote Sensing from Space Research Institute, Moscow, Russia in 1991. Before joining GEST in February 2002, Dr. Lyapustin was a Research Fellow for two years in the Universities Space Research Association (USRA) and assistant research scientist in JCET UMBC. Dr. Lyapustin actively works in 1D and 3D radiative transfer in planetary atmospheres. His current research interests are focused on retrievals of atmospheric aerosol and surface bidirectional reflectance from MODIS and future NPOESS VIIRS sensors using the time series analysis. His group has developed the AERONET-based surface reflectance validation network (ASRVN) - an operational system producing surface BRF and albedo from MODIS and MISR instruments at AERONET locations for global validation analysis and science applications. Alexei is a current science team member of MODIS and NPP Science Teams, of GOES-R Algorithm Working Group and an associate member of the VIIRS Operational Algorithm Team (VOAT). |
