Dr. Xiaoting Li joined Visa Research as a Staff Research Scientist in March 2022. Xiaoting received her Ph.D. in Information Sciences and Technology at Penn State University in 2022, and B.S. in Information Security from University of Electronic Sciences and Technology of China in 2017. Before joining Visa Research, Xiaoting worked as a Research Assistant at Penn State University. In her Ph.D. dissertation, she focused on studies of enhancing the robustness of different ML systems and exploring the applicability of adversarial machine learning in security-critical scenarios.
As a member of Artificial Intelligence team, her research interests span from Machine Learning/Deep Learning to Software Security and Program Analysis. In particular, she did extensive study on software fuzzing problem and adversarial machine learning among various model types. She has published multiple works in top-tier conferences, including International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR), SIAM International Conference on Data Mining (SDM), International Conference on Software Engineering (ICSE), AAAI Conference on Artificial Intelligence, and others.
