I am a staff research scientist at Visa Research. I received my Ph.D. in Information Sciences and Technology at Pennsylvania State Univerity in 2022, and my B.S. in Information Security from University of Electronic Sciences and Tehcnology of China in 2017. My research interests intersect Deep Learning, Graph Representation Learning and Software Security. Specifically, I have been extensively studying the robustness of different Deep Learning systems and exploring the applicabilities of adversarial machine learning in security-cirtical scenarios.

Miscellaneous

I love acrylic painting and traveling. I also enjoy shopping and sharing my personal thoughts about outfits on Red (an app for sharing life). For me, bug-free codes and chic clothes are always the source of happiness in life :D!
