Personal profile
Research Interests
Dr. Hu's group is a joint experimental and modeling research program studying atmospheric organic chemistry and air pollution. The overarching goal is to improve understanding of the chemical composition of the atmosphere and how it is influenced by human activities and natural processes. His research group uses a combination of field observations, satellite data, and atmospheric modeling to investigate the origins, chemistry, and transport of volatile organic compounds (VOCs), and their implications for air quality and climate locally and globally. Current projects focus on global tropospheric ozone budgets, long-term changes of trace gases in the atmosphere, land-atmosphere exchange of organic carbon.
