I am an Assistant Professor in the Department of Computer Science at University of Illinois at Urbana-Champaign (UIUC). My research covers a range of topics in Security and Privacy, Internet Measurement, Mobile Networks, and HCI, mostly from data-driven perspectives. My current projects are focused on the security and privacy of mobile and IoT systems, security of social computing systems, spear phishing, adversarial machine learning, and machine learning explanation. My work targets top conferences such as Usenix Security/CCS/NDSS/Oakland, IMC/WWW, and CHI/IMWUT/CSCW. At UIUC, I am affiliated with Security and Privacy Research at Illinois (SPRAI). I am a recipient of the NSF CAREER Award (2018), Google Faculty Research Award (2017), IMWUT Distinguished Paper Award (2019), ACM CCS Outstanding Paper Award (2018), and SIGMETRICS Best Practical Paper Award (2013)

Before joining UIUC, I worked as an Assistant Professor at Virginia Tech for three years (2016 to 2019). I obtained my PhD from UC Santa Barbara under the supervision of Ben Y. Zhao and Heather Zheng in 2016. I received my bachelor degree from Tsinghua University in 2010. I spent two summers at Microsoft Research Redmond in 2011 and 2014.
