 (New) I will join the Department of Information Systems at the University of Maryland Baltimore County as a tenure-track assistant professor in Fall 2017. If you are interested in working with me, please feel free to send me an email with your CV.

I am a Staff Research Associate, Alvin M. Weinberg Fellow at Data Architectures Team,  Computational Data Analytics GroupOak Ridge National Lab.

I got my Ph.D degree of Computer Science in 2014 from the University of California, Davis, advised by Professor Karl Levitt and Sean Peisert.  I obtained a bachelor degree of Electrical and Electronic Engineering in 2010 from the University of Hong Kong.

My research interests include security and resilience in distributed systems and cyber physical systems (sensor network, critical infrastructure systems). (link to my projects)

I have a blog page about the things that I'm interested in! Please go to my blog page if you are interested! 

If you are interested in my work or want to collaborate on any of the above topics, feel free to contact me.

CV, Feb 2017.

My Life

I come from Beijing, China. I speak Chinese (Mandarin and Cantonese) and English.

In my life outside of computer science, I enjoy a number of other activities, including traveling, yoga, video and computer games, and cooking.
