Research Interests

Atmospheric aerosols play an important role in the planet's climate. However, they are highly variable in their physical and chemical properties, as well as their spatial and temporal distributions. This makes quantifying their impacts challenging. My group uses field observations, both ground and airborne, to characterize particles and learn about their role in the folrmation of warm, and cold clouds.
