This research investigates the formation and chemical composition of atmospheric aerosol particles, particularly secondary organic aerosols formed through oxidation of organic gases. Using a large controlled atmospheric chamber, the work studies how environmental conditions influence aerosol chemistry, improving understanding of air pollution, climate impacts, cloud formation, and human health effects.

The researcher studies how clouds on distant exoplanets affect their climates and potential for life. Working with NASA, they model how exotic materials—like iron or sapphire clouds—absorb and reflect light. They found particle shape greatly influences temperature and habitability, helping determine whether alien worlds could support liquid water and life.
