Metrology & Dynamics

Real-Time 3D Shape, Deformation & Vibration

Pioneering high-speed optical frameworks combining stereoscopic vision, advanced Digital Image Correlation (DIC), and infrared active sensors (such as Microsoft Kinect) to characterize physical dynamics. Implemented algorithms capable of recovering micro-vibrations and recording acoustics directly from silent high-speed video frames.

Vibration metrology
Artificial Intelligence

Structured-Light & Deep Learning Integration

Creating neural network models (including hNet, MIMONet, and single-shot fringe-to-phase transformations) that reconstruct full 3D coordinates from a single structured light exposure. This replaces traditional multi-frame phase-shifting, eliminating movement artifacts and enabling robust real-time volumetric scanning of moving subjects.

Biomedical Engineering

Preclinical Transcranial Magnetic Stimulation (TMS)

Developing highly focused micro-coils featuring high-permeability magnetic cores to optimize rat motor cortex neuromodulation. Co-invented a high-density, subthreshold theta burst stimulation (hdTBS) protocol to study downstream neurocircuit mechanisms, fMRI brain mapping, and cocaine craving suppression mechanisms.
