I am a Senior Research Scientist in Dr. Sonia Kreidenweis's research group, within the Atmospheric Chemistry Program. My research interests at CSU lie in the area of aerosol-cloud interactions, particularly ice phase transitions of atmospheric particles for conditions present in various regions of the troposphere, including layer clouds in winter, cumulus clouds, and cirrus clouds. The goals of my research are to understand the way that aerosol particles of natural or anthropogenic origin determine the ice phase composition of clouds and in turn how clouds impact the distribution and nature of ice nucleating aerosols in the atmosphere. This information is important to the fundamental issue of how aerosols affect climate indirectly by impacting the radiative properties of clouds, latent heating of the atmosphere, and precipitation. Other members of the ice phase transitions study group at CSU include Dr. Tony Prenni, Dr. Gavin McMeeking, Dr. Yutaka Tobo, Mr. James Carpenter, Mr. Ezra Levin, and Ms. Christina McCluskey. Our research approach involves laboratory and field studies using specialized instrumentation, and numerical modeling studies from the process level to the global scale in collaboration with external investigators and the Center for Multiscale Modeling of Atmospheric Processes (CMMAP).
