About Me


	I am currently a PhD Candidate in Electrical & Computer Engineering Department in Carnegie Mellon University. My advisor is Professor Tonguz. I got my Master in ECE department in Carnegie Mellon University Thesis: Bounding the Performance of Multi-hop Cellular Systems for Real Time Traffic. Before I came to Carnegie Mellon, I was a reseacher in the National Key Laboratory of Switching Technology & Telecommunication Networks in China and a instructor in Beijing University of Posts & Telecommunication. I got my B.Sc. degree in Information and Electronic Engineering Department in Zhejiang University

Research


	I am currently working with image processing and tracking of eye movement for medical applications. It involves detection of pupil change, horizontal, vertical and torsional movement of human eyes under certain stimulations. Abnormal response in eye movement is related with problems in balance functions, diseases such as diabetic retinopathy. The accurate detection of eye movement is helpful in diagnizing or initial screening of these diseases. My previous research includes the Intelligent Network in Telecommunications .
