Dr. Marchand's research focuses on cloud microphysics and improving the representation of clouds and microphysical processes in climate and cloud resolving models. This includes developing remote sensing techniques to determine cloud properties from satellites, airborne, and ground-based instruments (especially radar and multiangle imagers), as well as applying remote sensing, in situ data, and instrument simulators in model studies. He is a frequent participant in field experiments, most recently in several Southern Ocean campaigns (SOCRATES, MICRE and MARCUS). Dr. Marchand is a member of the NASA CloudSat and MISR instrument teams and a longtime participant in the U.S. Department of Energy Atmospheric System Research program. Dr. Marchand earned his Ph.D in electrical engineering from Virginia Tech in 1997 and since that time has held research positions at Penn State University, the U.S. Department of Energy Pacific Northwest National Laboratory, and the University of Washington Joint Institute for the Study of the Atmosphere and Ocean. He is currently a research professor in the Department of Atmospheric Sciences at the University of Washington.
