Hi, I am Wenjie Xiong, currently a postdoctoral researcher at Facebook AI Research (FAIR). Before joining Facebook, I am the first Ph.D. student of Prof. Jakub Szefer in CASLAB in the Department of Electrical Engineering at Yale University.
My research interests are in hardware security, where I leverage hardware features to enhance the security of computer systems as well as identify and mitigate security vulnerabilities that are rooted in hardware design.
In particular, I have recently worked on designs of new Physically Unclonable Functions (PUFs), cryptographic applications leveraging physical properties of hardware, security verification of processor architectures, and attacks and mitigations of timing channels in caches.
I published multiple research papers in top-tier hardware security conferences and journals including HPCA, CHES, TIFS, TDSC, DATE. I am passionate about leveraging hardware to build secure systems.
