I am a fifth-year PhD student at Virginia Tech, advised by Prof. Wenjing Lou. I am also part of the CNSR-VT lab. My research interests include blockchain and network security. I am currently a Ph.D. Software Engineer Intern at Uber, working on multimodal data infrastructure.

I graduated with my B.S. in Information Security from Nankai University in Tianjin, China, in June 2020. Later, I graduated with an M.S. in IT Cyber Security from the University of Glasgow in the United Kingdom in January 2022.
