Xiangwen was born and raised in Beijing, China. Prior to arriving at Princeton, he earned a master’s degree at Peking University with a focus on urban air pollutant dispersion. His previous research mainly dealt with characterizing the distribution of traffic-related air pollutant in complex urban terrain by developing and using atmospheric models. He now works with Professor Denise L. Mauzerall and is interested in assessing air quality and human health co-benefits of urban decarbonization strategies including changing urban form and retrofitting urban energy infrastructure. He hopes his research could help provide solid policy suggestions on climate change and air pollution mitigation in developing countries like China.
