Tan Zhi Xuan is a Presidential Young Professor in the NUS Department of Computer Science, with a joint appointment at the A*STAR Institute of High Performance Computing (IHPC). Xuan received their Ph.D. in Computer Science from the Massachusetts Institute of Technology, and her B.S. in Electrical Engineering and Computer Science from Yale University. Xuan's research focuses on scaling cooperative intelligence via rational and model-based AI, spanning the areas of probabilistic programming, model-based planning, Bayesian inference, AI alignment, and computational cognitive science. Together with her research group, the Cooperative Systems & Intelligence (CoSI) lab, Xuan aims to reverse engineer the computational foundations of human cooperation and normativity, thereby enabling the development of AI systems that can cooperate as proficiently as humans, and the design of cooperative sociotechnical infrastructure for an increasingly automated future. Xuan was a recipient of the Open Philanthropy AI Fellowship in 2021 and the A*STAR National Science Scholarship in 2013. In recognition of their expertise in AI safety and alignment, Xuan was invited to participate in the RAISE.SG workshop on Singapore's National AI Strategy 2.0, and has given invited talks at the Simons Institute and the EAGx conference series. She also serves as an advisor to multiple AI alignment non-profits (Principles of Intelligent Behaviour in Biological & Social Systems; Meaning Alignment Institute) and as a board member of Welfare Matters, a non-profit addressing farmed animal welfare in Southeast Asia.
