Before joining the Sensor Physics Branch, he was a postdoctoral
research associate with the National Research Council from 1992 to
1994, a physical scientist with the University of Colorado/Cooperative
Institute for Research in the Environmental Sciences/NOAA Environmental
Technology Laboratory from 1994 to 2001, and a research scientist at
the Science Systems and Applications, Inc./NASA Goddard Space Flight
Center, Greenbelt, MD, in 2002. During these periods his research
activities included radiometer calibrations, radiative transfer
modeling, development of retrieval algorithms and ground-based
atmospheric remote sensing.
