Tyler Westenbroek
I am currently a Postdoctoral Researcher in the Paul G. Allen School of Computer Science & Engineering at the University of Washington, working with Abhishek Gupta. My research focuses on dexterous manipulation for robotics, by scaling RL training in simulation and developing efficient algorithms for real-world adaptation.
I received my PhD in Electrical Engineering and Computer Sciences from UC Berkeley (2023), working on machine learning and control under Shankar Sastry. I received my B.S. in Systems Engineering and Computer Science from Washington University, working with Humberto Gonzalez on hybrid systems.
