I am an Assistant Professor in the Department of Computer Science at University of Illinois at Urbana-Champaign (UIUC). I am also affiliated with the Department of Electrical and Computer Engineering (by courtesy), Security and Privacy Research at Illinois (SPRAI), and Informatics Programs of School of Information Sciences. My research covers a range of topics in Security and Privacy, Internet Measurement, and Data Mining. I am also interested in human factors in security. My recent projects are focused on security of social computing systems, cybercrime, adversarial machine learning, and machine learning explanation. My work is usually published in conferences such as Usenix Security/CCS/NDSS/Oakland, IMC/WWW, and CHI/IMWUT/CSCW. I am a recipient of the NSF CAREER Award (2018), Amazon Research Award (2021), 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 Ph.D. from UC Santa Barbara under the supervision of Ben Y. Zhao and Heather Zheng in 2016. I received my bachelor's degree from Tsinghua University in 2010. I spent two summers at Microsoft Research Redmond in 2011 and 2014.
