I am a Ph.D. student in the Department of Electrical and Computer Engineering at the University of Maryland, College Park, supervised by Professor K. J. Ray Liu. I obtained my Bachelor's degree in Astrophysics from Peking University in 2015, and my Master's degree in Electrical Engineering from New York University in 2017. My current research interests include but not limited to signal processing, millimeter waves, and the Internet of Things.

During my master's study, I was focusing on propagation models. I did mmWave measurements with Professor Ted Rappaport in 2016, in urban areas in NY and rural areas in VA. My thesis advisor, Professor I-Tai Lu helped me build a new propagation model at UHF accounting for street openings in urban street canyons.

I started playing chess at the age of five. I have earned many champions along the way. In 2003, I was select to participate in the World Youth Chess Championship on behalf of China.
During my master's study in New York, I was a member of the Marshall Chess Club and played games in many local tournaments.
In the first year of primary school, I met my Yangqin teacher Dr. Chen and became his first and the last student. I was awarded the first prize in the Global Chinese Music Festival in 2010. In college at PKU, I played leading Yangqin in the orchestra of Chinese Musical Institute (CMI) for four years, directed by Professor Bryan Bi. In 2012, we were invited to perform at the University of Edinburgh and Canongate Kirk.
