Feb 2021 – Dec 2022 Medical Imaging

ODT-based Visualization of PM2.5 Interaction with Cells

Investigated how fine dust interacts with macrophages and epithelial cells using Optical Diffraction Tomography and holographic microscopy.

Built a 3D label-free visualization workflow for PM2.5-cell interaction analysis.
Analyzed refractive index distributions to compare active and passive uptake patterns in real time.
Demonstrated a phototoxicity-free method for studying hard-to-label substances in biological systems.

Mar 2021 – Aug 2022 XR / AR / VR

SketchScope: Interactive Virtual Science Museum Platform

A multi-modal volume visualization platform enabling sketch-based exploration of internal structure without damaging the object.

Implemented bi-directional interactions across hand gestures, touch interfaces, VR headsets, and holographic displays.
Extended the system to HoloLens 2 with QR-code based volume placement for immersive museum experiences.
Focused on accessibility, education, and multi-device interaction design.
