Biography

Yuzhong Zhang received his bachelor’s degree in environmental sciences from Peking University in 2010 and his Ph.D. degree in atmospheric chemistry from the Georgia Institute of Technology in 2015. He then worked as a postdoctoral fellow at the Georgia Institute of Technology in 2016-2017 and Harvard University in 2017-2019. He joined Westlake University as a principle investigator in 2020.

 

Research

The air we breathe everyday consists of, in addition to a bulk of nitrogen and oxygen, a multitude of trace gases and particles. Some of these trace constituents are emitted to the atmosphere from human activities and natural processes, while some others are produced in the atmosphere through a cascade of atmospheric chemical reactions. These constituents account for only a tiny fraction of air (from parts per million down to even parts per trillion), as compared to the bulk of nitrogen and oxygen, but they play critical roles in Earth’s energy balance, have huge impacts on the health of human, animals, and plants, and are closely associated with critical environmental issues that we are facing today, for example, air pollution, acid rain, ozone hole, and climate change.


Research in Yuzhong Zhang’s group thrives to improve our basic knowledge that can help us fight these pressing environmental issues. He and his group develop novel modeling and analysis tools to interpret big environmental data collected from multi-platforms (e.g., satellite, aircraft, surface networks), and reveal mechanisms that regulate the distributions of key atmospheric species at varied spatial-temporal scales. Research topics includes atmospheric chemistry-climate interaction, methane emissions and its budget, light absorbing brown carbon, regional ozone pollution, and atmospheric oxidation power. Dr. Yuzhong Zhang has so far published ~30 peer-reviewed papers on these topics including in top journals such as Science Advances, Nature Geoscience, and PNAS.
