I build and study intelligent systems at the intersection of Generative Vision Models, Embodied AI / Robotics, and Interactive XR:
- 🤖 Humanoid Teleoperation & Motion Capture: Full-body real-time teleoperation and retargeting at 50 Hz for the Unitree G1 EDU (29 DoF) humanoid robot using PICO 4 & ankle motion trackers (g1-pico-suspended-arm-mocap).
- 🥽 VR Locomotion & Scene-Aware Systems: Real-time Inverse Kinematics (IK) avatar tracking with VIVE trackers in Unity (CycleWalkingVR) and context-aware 3D/VR outfit retrieval (SceneFit / SceneFit-Backend).
- 🧠 Generative AI & Computer Vision: Building diffusion pipelines from scratch (Anime-Face-Pytorch-Stable-Diffusion), concept erasure & evaluation benchmarks (InfinityCE, CE-Eval), and multi-label vision models (Multi-Label-Classification-with-MNIST-Digits).
- 🌐 Core Systems & Graph Algorithms: Reliable UDP (Go-Back-N + AIMD + SHA-256) hybrid file transfer protocol (hybrid-ftp) and large-scale road network routing with Contraction Hierarchies & Transit Node Routing (Road Network Routing).
