Aerosols, tiny solid particles or liquid droplets suspended in air, are key elements in
the atmosphere of the Earth system, influencing air quality, climate and human health
in the Anthropocene. They scatter or absorb sunlight, serve as nuclei for clouds and
precipitation, and adversely affect human health. Aerosol formation and evolution
involve detailed gas-phase atmospheric chemistry and gas-particle interactions. The
interaction of aerosols with atmospheric water, as well as their size and physical
properties, are key to much of their behavior. Our research mainly focused on (1) haze
chemistry that drives the formation of extreme air pollution, (2) aerosol nano-size
effects and phase transition, (3) aerosols’ health and climate impact. The overall goal
is to obtain a predictive understanding of the origin, fate, and impact of atmospheric
aerosols to address the grand challenge of an actionable projection of future climate
and environment in the Anthropocene.
