Jie Xu

I am a Ph.D. student at MIT CSAIL, advised by Professor Wojciech Matusik in the Computational Design and Fabrication Group (CDFG). I obtained my B.Eng. from Department of Computer Science and Technology at Tsinghua University with honor in 2016. During my undergraduate period, I worked with Professor Shi-Min Hu in the Tsinghua Graphics & Geometric Computing Group and with Professor Stelian Coros as an exchange student at CMU. My research mainly focuses on the intersection of Robotics, Simulation, and Computational Fabrication. Specifically, I am interested in the following topics: Robotics Control, Reinforcement Learning, Differentiable Physics-based Simulation, Robotics Control and Design Co-Optimization, and Sim-to-Real.
