Yujie is a first-year (Fall 2020) PhD student in the Science, Technology and Environmental Policy (STEP) Program at the Princeton School of Public and International Affairs. At Princeton, he will do his doctoral research under the direction of Professor Denise Mauzerall, which will center on air pollution and relevant public policies. Yujie wants to utilize scientific tools to shed light on climate change and air pollution problems in developing countries, such as China and India, thus formulating practical and effective policies to mitigate these problems while maximizing environmental benefits and minimizing economic costs.

Yujie was born and raised in Luoyang, which is one of the most historical cities in China. Before coming to Princeton, Yujie received his master's degree in environmental science from Zhejiang University and earned his bachelor's degree in environmental engineering, with a second major in business administration, from Southwest Jiaotong University. His previous research focused on using chemical transport models and other numerical models to characterize air pollution in China.
