Landscape heterogeneities can have pronounced effects on atmospheric boundary layer processes. Examples include a modification of the boundary layer growth and the generation of mesoscale circulations. My research focuses primarily on the investigation of these processes in hilly and mountainous terrain using a combination of field studies, data analysis, and numerical modeling techniques. I seek to apply my expertise to problems in a multi-disciplinary context such as found at the interface with ecology, atmospheric chemistry, and hydrology. Examples include the venting and regional transport of aerosols and the estimation of regional CO2 fluxes.
