Research Interests

My interests lie in aerosol-cloud-precipitation interactions and implications for climate change. I focus on process-level studies using high-resolution models and observations (aircraft and surface remote sensing) at the cloud scale. I also focus on lidar and radar remote sensing of clouds and aerosol, modeling and remote sensing of aerosol-cloud interactions (“indirect effects”), “cloud burning” or the “semi-direct effect,” and self-organization of cloud systems. I have authored or co-authored more than 150 peer-reviewed articles.

Professional Experience

I have worked closely with ARM data and served on ARM and ASR steering committees, most recently the ASR Cloud Aerosol Precipitation Interactions (CAPI) Working Group. I was a co-chair of the Climate and Environmental Sciences Division ARM/ASR High-Resolution Modeling Workshop, which led to recommendations for the ARM Symbiotic Simulation and Observation (LASSO) Routine Large-Eddy Simulation project.
