Summary

I am a professor in the Atmospheric Science Program located in the Department of Geography. My group and I conduct research on cloud microphysics and dynamics, and mesoscale organization of cloud systems.

I teach the 2-semester undergraduate dynamic meteorology sequence, physical meteorology (occasionally), and a graduate-level numerical modeling course.

Education

Ph.D., Atmospheric Sciences, University of Washington

B.S., Meteorology, University of Oklahoma

Research

My research explores different manifestations of precipitating convection, ranging from drizzling boundary layer stratocumulus to deep, highly organized mesoscale convective systems. A common thread of interest between these phenomena is the concept of mesoscale organization and its role in promoting scale interactions, in particular how mesoscale and cloud-scale processes serve as upscale agents of change for the large-scale flow or cloud coverage. Guided by observational results, I employ large eddy simulation, cloud resolving models, and mesoscale models to investigate cloud system processes.
