Education

I am an Assistant Professor in the Department of Computer Engineering at University of California Santa Cruz. I primarily work on the fundamental problems of computer networks, systems, and security. I received the NSF CAREER Award in 2018.

I was an assistant professor in the Department of Computer Science at University of Kentucky, and a faculty member of the Laboratory for Advanced Networking during 2013-2016.

I received my Ph.D. in Computer Science from University of Texas at Austin in 2013. My advisor was Simon S. Lam, meaning I am a part of the Leonard Kleinrock's family tree. I am the recipient of the James C. Browne Graduate Fellowship in 2012 (list of Browne Fellowship awardees for 2001-2012). I interned at AT&T Labs-Research in May-Aug, 2012. I got my M.Phil. from Department of Computer Science and Engineering at Hong Kong University of Science and Technology, where I worked with Prof. Lionel M. Ni (now Provost at University of Macau), and also had close collaboration with Prof. Yunhao Liu (now Dean of School of Engineering, Tsinghua University). I received my Bachelor's degree (highest honor) from Department of Computer Science, Nanjing University in 2006, under the supervision of Prof. Jiafu Xu and Prof. Fangmin Song.

I was born in Suzhou, Jiangsu, China.
