Thank you for your visit.
I am Letian Wang, a visiting student researcher at the MSC Lab at the University of California, Berkeley, supervised by Prof. Masayoshi Tomizuka. I finished my bachelor's degree and am in a master's program at Beihang University, Beijing, China.
My research interest includes machine learning, optimization, control theory approaches and their applications to motion planning, behavior prediction, and decision making for autonomous vehicles and robotics.
I was also a research assistant at the Robotics Institute of Hong Kong University from August 2018 to October 2018. Under the supervision of Prof. Zexiang Li, I worked on strategies and algorithms of motion planning and trajectory tracking for Tailsitter VTOL UAV.

I am Letian Wang, currently a Ph.D. student at the University of Toronto, where I am so fortunate to be supervised by the brilliant researcher Prof. Steven Waslander in the TRAIL Lab. Previously, I was also fortunate to do research with/at:
-
Prof. Changliu Liu, Robotics Institute at the Carnegie Mellon University (2020-2022)
-
Prof. Masayoshi Tomizuka, MSC Lab at the University of California at Berkeley (2019-2020)
-
Prof. Fu Zhang, Robotics Institute at the Hong Kong University of Science and Technology (2018)
I obtained my bachelor's degree and master's degree with highest honor in 2018 and 2021 respectively, both at Beihang University (Beijing University of Aeronautics and Astronautics), China, supervised by Prof. Qingyun Wang.
My research interest lies in robotics, autonomous driving, and machine learning. Specifically, my interest is triggered by a range of human-robot interaction (HRI) applications, e.g., transferable and adaptable behavior generation, socially-compatible human-like behaviors in decision making, robust and fast learning from human demonstrations or historic information with uncertainty, and safe control/RL in multi-agent scenario with guarantees.
To address challenges in HRI, a highly interdisciplinary area, I leverage techniques from multiple areas, including (inverse, hierarchical)reinforcement learning, probabilistic robotics, graph neural network, control theory, convex optimization, cognitive science, etc.
I have many robotics experiences, won the Best Paper Award Hornoable Mention at RA-L, first place in the CARLA autonomous driving leaderboard, first prize in the National Challenge Cup 2017 (全国挑战杯一等奖, the highest technology competition for college students in China), and was fortunate to co-found a start-up in industrial UAVs.
