I'm an Assistant Professor at VinUniversity, a Visiting Professor at IAS, TU Darmstadt, and Director of Foundation AI at VinRobotics, where my team builds the RL stack for high-payload humanoid locomotion, humanoid VLA architectures and training recipes, and the model optimization and edge-deployment toolchain.
I study how robots can plan, learn, and act reliably with limited computation and data. My group works on three directions that increasingly fit together:
- Parallel planners. We represent candidate plans and their costs as tensors so GPUs can search many of them at once (tensor search), and pair this structure with optimal transport and diffusion / flow-matching priors for long-horizon, multimodal, non-convex problems.
- Scaled-down robot foundation models. VLA policies that adapt from fewer demonstrations and run on affordable onboard computers: native low-bit quantization, a C++ inference runtime, and shared SIMD kernels that run policies on CPUs down to a Raspberry Pi 5.
- Whole-body control through contact. Force-aware controllers that let 70 to 85 kg humanoids respond to contact and changing payloads with their arms, torso, and legs together.
Next up: whole-body VLAs trained on contact-rich data, with planners checking their actions and compliant controllers executing them.
On weekends, I write JAX/PyTorch simulators for curved spacetimes (Kerr black holes, the Penrose process, warp-drive energy conditions), because these physics are art!
