I am looking for self-motivated Ph.D. students (Spring/Fall 2021). Please feel free to contact if interested. [Ads]
If you are a UTK student and want to do system research with me, drop me an email or stop by my office. Let's talk!

about

I am an Assistant Professor in the Min H. Kao Department of Electrical Engineering and Computer Science at The University of Tennessee, Knoxville. I lead MoSIS Lab @ UTK. Before joining UTK, I received my Ph.D. degree from Wireless Information Network Laboratory (WINLAB), Rutgers University in 2019, supervised by Prof. Yingying (Jennifer) Chen.

My research interests span Mobile Sensing and Computing, Cybersecurity and Privacy, Smart Healthcare, Intelligent Systems and Machine Learning. I regularly publish papers in premier venues (e.g., ACM MobiCom, ACM CCS, ACM MobiHoc, ACM MobiSys, IEEE INFOCOM and ACM UbiComp). I also hold 4 U.S. patents, two of which have been licensed to industrial companies. Meanwhile, my research has been regularly featured in the media including BBC News, Yahoo News, MIT Technology Review, NBC New York, IEEE Spectrum, WCBS TV and Voice of America TV, etc.
