Research Interests

Dr. Zhu’s research program has been designed to investigate and understand what controls the atmosphere’s energy balance and how chemical reactions impact composition, pollutant and oxidant formation in the earth’s environment. Answers to these questions are highly relevant to understanding atmospheric climate change, as well as controlling air pollution and protecting public health. Her research interests include tropospheric chemistry, kinetics and photochemistry of homogeneous and heterogeneous atmospheric reactions, atmospheric physics and chemistry and their influence on atmospheric radiative balance, new technique development.
