About Me

I am a Ph.D. candidate in the Computer Science Department at Virginia Tech since 09/2018. I am advised by Prof. Yaling Yang and co-advised by Prof. Young (Yang) Cao. My research covers a range of topics in Security and Privacy, Secure Localization, and Mobile Networks.

I received my bachelor's degree as the top 1 student (among 240) from University of Electronic Science and Technology of China (UESTC) in 2018. I also received a bachelor's degree with First-Class Honors from University of Glasgow (UoG) through the UESTC-UoG Joint Program in 2018. I was awarded the excellent graduate title from Sichuan Province Government and UESTC. I was a visiting scholar at Michigan State University during the 2017 summer, advised by Prof. Jiayu Zhou.
