I am a PhD student at UC Berkeley advised by Prof. Masayoshi Tomizuka and Prof. Andrea Bajcsy at Carnegie Mellon University. I am also a Qualcomm Innovation Fellow , a World Artificial Intelligence Conference Rising Star , and a Robotics: Science and Systems Pioneer.

My research lies in the intersection of robotics and AI with a focus on safe alignment between embodied agents and humans. I tackle the alignment and safety problems that emerge throughout the life-cycle of foundation models in robotics, ranging from: training (wherein we need to collect and quantify what kinds of embodied data will enable the desired robotics capabilities), to fine-tuning (wherein we must align these models with humans), to deployment (where these models must run in real-time, reliably detect out-of-distribution scenarios, and confidently handover control to fallback-strategies). I ground my work through a variety of applications, from autonomous cars, to personalized robots, to generative AI and in experiments with real human participants.

During my PhD study, I am a long-term intern at Waymo (2022-Now), working on foundational motion model for autonomous driving research (including pre-training, post-training preference alignment, and distillation for onboard deployment). I am fortunate to have the opportunity to intern at the Autonomous Vehicle Research Group at NVIDIA Research, working on visual foundational models for autonomous driving (2023-2024). Previously, I was a research intern at WeRide, Honda Research Institute, and Qualcomm AI Research.

I sincerely appreciate the fellowship support from WeRide (thank you! Dr. Yan Li, Dr. Hua Zhong, and Dr. Tony Han) for funding my research in my first two years of study!

I am actively looking for an industrial RS or a postdoctoral position! Please reach out to me if you think I might be a good fit!
