Professional Interests
My field of interest is in ice microphysics, including the processes that lead to ice particle nucleation and growth, the effects of ice clouds on the earth's radiation budget, the reprentation of ice processes in models from weather forecast to climate scales, and the retrieval of ice cloud properties from ground-based and spaceborne remote sensors.
