Research Areas
Dr. Liu's group conducts interdisciplinary research on atmospheric aerosol particles and their influences on air quality, human health, and climate. We, together with our collaborators, conduct laboratory experiments, field measurements, and atmospheric chemistry modeling to improve the understanding of the processes and properties of aerosol particles.

We are currently interested in the following research topics:
1) Characterizing the physicochemical properties of organic aerosols, such as the volatility, photolysis, hygroscopicity, and optical properties;
2) Development of new laboratory techniques for aerosol characterization;
3) Modeling of aerosol emissions, transport, and deposition of aerosols in the paleoclimate, using constraints from ice core records;
4) Health effects of particulate matter on neurological disorders.
