Xiao Ma
I am a staff research scientist at ByteDance Seed, where I lead the robotic foundation model team. Prior to that, I pursued my PhD at National University of Singapore, advised by Prof. David Hsu. I have worked as research scientist at Dyson Robot Learning Lab, led by Dr. Stephen James and at Sea AI Lab, hosted by Prof. Shuicheng Yan and Dr. Min Lin. My research spans across reinforcement learning, robotics, and multi-modal models.
