Research Interestests

My research has been focused on parameterizations of boundary-layer turbulence, shallow convection, and cloud-aerosol interactions. I have made extensive use of both ARM data and Value Added Products, including those related to the planetary boundary layer and turbulence, clouds, aerosol, and surface radiation.

Professional Experience

I served as Primary Investigator (PI) for the recently completed Two-Column Aerosol Project (TCAP), which included the deployment of both the ARM Mobile Facility and ARM Aerial Facility to Cape Cod, Massachusetts. I was also co-PI for the DOE-supported Cumulus Humilis Aerosol Processing Study (CHAPS), which investigated cloud-aerosol interactions in shallow cumuli near Oklahoma City, Oklahoma. I have also participated in several other field studies supported by the National Science Foundation, the Department of Homeland Security, and the DOE Wind Power program.
