Wei Zhan serves as a Co-Director of Berkeley DeepDrive, a research center at UC Berkeley focusing on AI for autonomy, mobility and robotic applications. He is an Assistant Professional Researcher at UC Berkeley leading the autonomy group of MSC Lab with 10+ Ph.D. students and Postdoc. His research interest lies in AI for autonomous systems leveraging control, robotics, computer vision and machine learning to tackle challenges involving a large variety of sophisticated dynamics, interactive human behavior and complex scenes in a scalable way, and make the autonomous system sustainably evolve.
He received his Ph.D. degree from UC Berkeley. His publications received the Best Student Paper Award in IV’18, Best Paper Award – Honorable Mention of IEEE Robotics and Automation Letters, and Best Paper Award Finalist of ICRA’24. One of his publications also got ICLR’23 notable top 5% oral presentation. He led the construction of INTERACTION dataset and the organization of its prediction challenges in NeurIPS’20 and ICCV’21.
He is actively looking for talented applicants (as Postdoc, Ph.D. student, visiting student or local Berkeley Master’s/undergrad student) to working with. Please fill in the form if you are interested.
