Dr. Xin Wei

Ph.D. Graduate, Spring 2021


Hometown: Qiqihar, Heilongjiang province, China.

Xin Wei was born in Qiqihar, a northeastern city in China. She received her bachelor’s degree in Environmental Engineering at Beijing Normal University. In 2015, she moved to the United States and continued her education at Carnegie Mellon University, as a Master’s student. She joined the S3 group in August 2017 to pursue her Ph.D. at USC. Xin is interested in research topics at the intersection of energy and desalination. Xin graduated with her doctorate in Spring 2021 in Environmental Engineering  at the University of Southern California.She was co-advised by Dr. Amy Childress and Dr. Kelly Sanders.
