Tianyi Wang

I am currently a research fellow at School of Computing (SoC), National University of Singapore (NUS), working with Prof. Mohan Kankanhalli. My research interests include Deepfake Detection, Misinformation Detection, Multimedia Forensics, and Generative AI.

Before joining NUS, I was a research fellow at College of Computing and Data Science (CCDS), Nanyang Technological University (NTU). I received my Ph.D. dgree in Computer Science (CS) at the University of Hong Kong (HKU), supervised by Dr. Kam Pui Chow. I received my double-major B.S. degree in Computer Science (CS) and Applied & Computational Mathematical Sciences (ACMS) at the University of Washington (UW) in Seattle.
