01 · NANOPHOTONICS

Nanophotonic structures for radiation sensors

We engineer photonic crystals, metasurfaces, microlens arrays, and nanoscintillators directly on scintillation crystals to control how light is generated, extracted, and steered. By pushing past the light-collection limits of conventional detectors, we target faster timing, higher sensitivity, and clearer images at lower radiation dose.

02 · SIMULATION

Photon and particle transport modeling

We pair Monte Carlo particle transport (GATE / Geant4) with nanoscale optical simulation (FDTD, Lumerical) to model radiation interactions, scintillation emission, and photon propagation through nanostructured surfaces. These multi-scale simulations let us optimize detector geometry and light-collection efficiency before anything is fabricated.

03 · DETECTION SYSTEMS

Radiation detection system development

We build complete detection systems end to end — from SiPM front-end electronics and readout modules to deployable field platforms. Our work spans compact, high-resolution PET/SPECT detectors and real-time environmental and marine radiation monitoring, including mobile gamma spectroscopy on unmanned vehicles and in-situ gamma monitoring systems.

04 · AI IMAGING

AI-driven medical image analysis

We develop deep-learning methods — such as 3D U-Net architectures — for personalized voxel-level internal dosimetry, image-quality enhancement, and dose reduction in nuclear medicine. Data-driven models turn raw PET/CT signals into accurate, patient-specific quantitative maps.
