Professional overview

My work at NCAR involves the study of ice cloud microphysics, basically the shape, size, and number of ice crystals in clouds. My group regularly participates in aircraft field campaigns where we mount instruments on aircraft and the fly through clouds in order to better understand the ice particles that make up the clouds. Results from this research is used by the weather forecasting and climate modeling communities in an effort to improve the interpretation of ice clouds in the models. The Publications tab will give you an idea of the type of research that I do.

For the past several years, I have been involved in the American Climber Science Program which is a volunteer organization that conducts scientific research in mountain environments. For the past four years, we have conducted research expeditions to the Cordillera Blanca region of Peru. For more details, look at the Peru tab.
