About

I am a Ph.D. candidate in Department of Computer Science at Purdue University. I work in PurSec Lab under the supervision of Prof. Dave (Jing) Tian. My research interests lie in the field of computer and network security. In particular, I am interested in secure architectures for next-generation networks and systems, including cloud networking, software-defined networking (SDN), intent-based networking (IBN), and programmable networking. Before joining Purdue, I worked in the industry for almost 4 years as a research engineer to design and develop SDN and cloud networking products.
