I am a robotics research manager at NVIDIA Research. I lead the Simulation and Behavior Generation (SBG) team within the Seattle Robotics Lab (SRL), which is directed by Dieter Fox. My team currently focuses on learned simulators, automated data generation, reinforcement learning, imitation learning, force and tactile sensing, high-performance control, and sim-to-real transfer. We are exploring applications to multi-step tabletop manipulation, robotic assembly, dexterous manipulation with anthropomorphic hands, and humanoids. Previously, I have worked on projects in cardiovascular biomechanics, precision machine design, human gait biomechanics, surgical robotics, soft robotics, finite element simulation, solid/fluid/structural mechanics, parameter inference, self-supervised learning, differentiable simulation, deformable-object manipulation, contact simulation, and machine-learning infrastructure.
