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 AI Security. Specifically, I have been extensively studying the robustness of different Deep Learning systems and exploring their applicabilities in text and graph domains. At Visa, my expertise is channeled towards advancing graph learning methodologies, model explainability, and deep tabular learning techniques. These endeavors are meticulously tailored to address complex, real-world financial scenarios.
