For more information, here is my CV.


I am a postdoc with Professor Rajesh Gupta affiliated with CSE and HDSI at UCSD. I earned my Ph.D. in Computer Science at the University of Virginia in 2018. My PhD adviser was Professor Kamin Whitehouse.

My research lies at the intersection of Cyber-Physical Systems, Data Mining, and Machine Learning, with a particular interest in energy-efficient systems. My recent work is focused on interpreting, organizing, and navigating through sensor data with minimal human input.

I earned my B.S. from Beijing University of Posts and Telecommunications (aka BUPT, or in Chinese 北邮) in 2012, majoring in Electrical Engineering.

I am an avid photographer.
