Research InterestsCurrently, a poor understanding of particles in the atmosphere and the clouds that form on them limits our ability to understand and quantify global warming. The focus of our research is to develop a better understanding of how natural and anthropogenic aerosol particles may influence aerosol/cloud interactions on local to global scales. Using novel analytical techniques, we can observe ice cloud nucleation under atmospheric conditions. Through a combination of field studies and laboratory experiments, we plan to explore how concentration, chemical composition, surface chemical reactions, and shape of aerosols may impact cloud formation and properties.
