Hi, my name is Zhizheng Liu (刘知æ£). I am currently a fourth-year Ph.D. candidate in Computer Science at Vision and Autonomy Intelligence Lab (VAIL) at UCLA. Before that, I earned my bachelor’s degree from the SJTU-UM Joint Institute (now SJTU Global College) and my master’s degree from ETH Zurich.
I work on a fundamental problem in embodied AI: How to enable general intelligent agents to understand and interact with humans in the physical world?. To address this challenging problem, my PhD research focuses on closing the real-to-sim gap for human-centric robotics with data-driven simulation. To this end, my work involves monocular 4D human-scene reconstruction, using the reconstructed data for generative modeling of pedestrian motion, and transferring these digital twins into simulation environments for scalable robot training and evaluation.
Throughout my research journey, I have been fortunate to receive invaluable guidance and support from many people. I am especially grateful to Dr. Tao Ma and Prof. Yikang Li, who first introduced me to research, and to my PhD advisor Prof. Bolei Zhou, whose continuous mentorship has been instrumental in shaping my view of research and life.
Hope you find my research interesting or useful and feel free to reach out if you want to discuss anything!
