Aug. 2016Started PhD at University of Pennsylvania


I am a first year PhD student at Penn studying Computer and Information Science supervised by Prof. Boon Thau Loo. My research interests are building distributed systems to tackle big data problems. I also have interests in networking, cloud computing and machine learning. Before Penn, I had my postgraduate education at Tsinghua University in Computer Science. I received my B.E. degree from Harbin Institute of Technology with first class honors.
