Dr. Liu's main research interests lie in understanding the processes affecting atmospheric composition in the troposphere and lower stratosphere, specifically the sources, chemical evolution and transport pathways.


Dr. Junhua Liu received a Ph.D. in Climatology/Paleo-climatology in 2008 from Duke University and a B.S. in Geochemistry in 2002 from University of Science and Technology of China. She worked as post-doctoral fellow and research associate at Harvard University on seasonal and interannual variations of carbon monoxide (CO) in the tropical troposphere and lower stratosphere and its inference for vertical transport using Aura satellite data and the GEOS-Chem model.

Dr. Liu joined USRA/GESTAR in Nov 2013. Her current research focuses on quantifying the factors controlling the observed interannual variations and trends in tropospheric O3 and precursors during the past 20 years using an ensemble of satellite, aircraft, surface observations and GMI model, and investigating their interaction with the Earth’s climate.
