Summary of Experience
My experience is focused on improving our understanding of the Earth's climate through studies of how aerosols and clouds interact with the solar and thermal electromagnetic radiation within our atmosphere.  Research has centered on coupling state-of-the-art models with observations from satellites and surface instrumentation in order to derive the properties of aerosols and clouds, and determine their effect on the Earth's energy balance.  The subject of research has varied from broad climate response issues to in-depth analyses including: the radiative effects of cirrus clouds and (nonspherical) scattering by ice crystals, 3-D radiative transfer in cloudy skies, continuum water vapor absorption, the effects of stratus cloud inhomogeneity on climate model simulations, and the impact of pollution and desert dust on the Earth's energy balance.  This work has been conducted in association with the Department of Energy's Atmospheric Radiation Measurement (ARM) Program [http://www.arm.gov/], the International Global Atmospheric Chemistry (IGAC) Program's Asian Pacific Regional Aerosol Characterization Experiment [ACE-Asia; http://saga.pmel.noaa.gov/aceasia], and NASA's Earth Science Enterprise [http://earth.nasa.gov/Introduction/index.html] Global Water and Energy Cycle (GWEC) Research Program.
