Welcome to my homepage!

I am currently working towards my Ph.D. degree under the supervision of Prof. Xiaoli Ma in Center for Signal and Image Processing (CSIP), School of Electical and Computer Engineering at Georgia Tech. My research focuses on statistical signal processing for wireless communications, telecommunications, and information theory. I have been working on both theoretical analysis by applying signal processing techniques such as lattice reduction algorithms onto wireless transceiver designs and fundamental limits, and practical implementation by designing VLSI architecture for communications algorithms. Based on my research record, I have received Outstanding Research Award from CSIP in Fall 2008.
