I am a Ph.D. student in the Computer Science Department at Virginia Tech, advised by Prof. Bo Ji and Prof. Peng Gao. My research interests broadly fall within the areas of system security and privacy, specifically on emerging computing platforms and complex systems, including recently proposed programmable switches and SmartNICs. Building upon this, I am particularly driven to develop secure, scalable, and intelligent primitives embedded within the network infrastructure, enhancing its security and robustness.
