Tianji Cai is a Distinguished Researcher at the School of Physical Science and Engineering, Tongji University. Before returning to Shanghai, she was a postdoctoral research associate in the Fundamental Physics Directorate at the SLAC National Accelerator Laboratory, and a research affiliate at the Lawrence Berkeley National Laboratory. She obtained her Ph.D. degree in 2023 at University of California, Santa Barbara, and holds two bachelor's degrees from Duke University and Shanghai Jiao Tong University. 

Her research explores the interface between fundamental High Energy Physics (HEP) and Artificial Intelligence (AI), where she develops first-principles AI algorithms to probe collider phenomenology and, conversely, uses concepts from HEP to deepen our theoretical understanding of AI systems.

Welcome to our new research team "The Ψai Lab -- Towards Scientific AI rooted in Fundamental Physics"! We seek enthusiastic explorers—whether you are an undergraduate, graduate, or postdoctoral researcher. Here, you will have the opportunity to collaborate closely with faculty and peers from world's top universities, as we build a vibrant, international team together. Join us in pushing the frontiers of physics and the nature of intelligence itself.
