Tenured Scientist

My research focuses on the processes that drive the properties and evolutions of atmospheric aerosols and the interactions between aerosols and clouds. The current research topics include: (1) aerosol properties and processes under natural conditions that were prevalent during pre-industrial era; (2) nucleation and new particle formation; (3) aerosols in the marine environment; (4) effects of aerosols on cloud microphysical properties and macrophysical structure; (5) development of advanced aerosol instruments with the focus on aircraft-based deployments.
