I am Yufan Wei.
I am a second year Ph.D. student at University of California, San Diego, advised by Prof. Biwei Huang and working close with Dr. Kun Zhou. My research focuses on causal intelligence and embodied ai, with a particular interest in representation level across policy model and world model.
I obtained my Bachelor’s degree in Computer Science at University of Minnesota while spend my first 2 years at Beijing University of Posts and Telecommunications.
