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.


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.
