Gang Wang

PhD Student

I am a final-year Ph.D. student in the Department of Computer Science at UC Santa Barbara. I work in SAND Lab, co-advised by Professor Ben Y. Zhao  and Heather Zheng.  I received my bachelor degree of Electronic Engineering at Tsinghua University in 2010. I was a research intern at Microsoft Research Redmond in the summers of 2011 and 2014, working with Cormac Herley, Jay Stokes, Weidong Cui, and Helen Wang.

My primary research interests are Security and Privacy, Online Social Networks (OSNs), Crowdsourcing and Mobile Networks. Much of my work is measurement-driven and modeling based. My interests in Security and Privacy are closely related to web services like OSNs and crowdsourcing systems. The goal is to uncover emerging threats and develop efficient defense techniques. Here is my CV.
