Research Projects

  • Aug 2024 - Present
    Simulated Patient: Animatable 4D Head Avatars
    3D Vision & Computer Graphics · PyTorch, CUDA, C++, OpenGL, pycolmap
    • End-to-end pipeline reconstructing photorealistic, animatable 4D head avatars with 3D Gaussian Splatting from sparse multi-view RGB captures, used as patient faces in elderly-care training.
    • Removed explicit camera calibration by refining feed-forward coarse pose estimates with pycolmap to supervise a deformable cross-view point-map network (UR 2026, first author).
    • Customized the Looking Glass Core SDK to stream 3DGS avatars in real time on holographic displays; wrote CUDA kernels for faster 3DGS rendering on an RTX 4060 (ICEIC).
  • Jan 2022 - Present
    Simulated Patient: Generative Facial Behavior
    Generative Behavior · Python, PyTorch
    • Data-driven 3D head avatar that reacts to speech and visual stimuli in in-the-wild scenarios, driving the digital twin's facial behavior (IEEE TCSS; REACT 2024 Challenge winner).
    • Converted monocular video into 3DMM animations for dataset acquisition; designed a multi-view stereo tracker with learnable camera parameters for better alignment.
  • Jan 2022 - Present
    Simulated Patient: Robotic Arm for Elderly Care Training
    Robotics & Mixed Reality · Python, ROS 2, Unity/Unreal
    • Prototyped a robotic shoulder-arm complex giving the digital twin a physical body for Range-of-Motion (ROM) training.
    • Pain-response facial expressions modulated by the trainee's performance, integrated into a VR environment.

Experience

  • Sep 2021 - Present
    Postdoctoral Researcher (Oct 2026 - Present) · Research Assistant (Sep 2021 - Sep 2026)
    Ritsumeikan University, Osaka, Japan
    • Mill Test Certificate Validator (industry collaboration, Jan 2025 - Present): deep-learning pipeline verifying PDF mill test reports at 99% accuracy, combining tabular layout detection, text recognition, and template matching (Python, PyTorch, Flask).
    • CAD Press-fit Analysis (industry collaboration, Sep 2021 - Mar 2024): pairwise press-fit analysis tool for electrical wiring-harness CAD, validated with PyBullet physics simulation, with a Qt/PythonOCC GUI. Managed the two-year project, including monthly client reporting and on-site technical consultations.
  • Sep 2019 - Aug 2021
    Backend / AI Engineer
    VNG Corporation, Ho Chi Minh City, Vietnam
    • High-load data pipelines and ad-delivery APIs handling millions of requests per second; operated highly available Kafka streams for ad payment services.
    • CTR prediction models (Factorization Machines, Logistic Regression, clustering) for real-time bidding and constrained ad allocation, evaluated via simulation-based staging and production A/B tests.

Education
