Basic Info

I am currently on a temporary rotation as a Program Director at the National Science Foundation. My program responsibilities there span Information Integration and Informatics (III), Secure and Trustworthy Cyberspace (SaTC), and BIGDATA.

I received my Ph.D. in Computer Science from Texas A&M University in 2006 under the advisorship of Dr. Wei Zhao and Dr. Jianer Chen, and my B.S. in Computer Science from Peking University, China, in 2001. Before joining GW in 2008, I was an Assistant Professor of Computer Science at the University of Texas at Arlington from 2006 to 2008.

My research focuses on data analytics and information security/privacy, and is currently supported by National Science Foundation, Army Research Office, and Qatar Foundation. My work has received several awards, including the NSF CAREER award in 2008, Best Paper Awards from IEEE ICC 2013 and IEEE NAS 2010, the Best Student Paper Award from ACM CIKM 2013, and a Best Paper Nomination from IEEE ISI 2015. My work on technology transfer was also recognized by the GW Technology Transfer Innovation Price and the first place finish at the GW Business Plan Competition, both in 2012.
