Radiation detector, system design and applications:

• High performance (high resolution, timing resolution and depth-of-interaction capable) detector design and prototyping for nuclear medicine
• Signal processing, Monte Carlo simulation and imaging reconstruction
• Pulse Shape Discrimination (Neutron, Gamma-ray, Beta particle)
• High speed x-ray imaging system for electronic component inspection

Application specific integrated circuit (ASIC) front-end electronics (analog and mixed signal) for radiation detectors:

• CMOS front end readout circuits such as preamplifier, shaping amplifier and analog-digital converter for high speed photosensors (avalanche photodiode and silicon photomultiplier) and semiconductor radiation detector (CdTe, CZT, etc).
• Radiation hardened (rad-hard) CMOS circuits employing radiation-hardening-by-design (RHBD) techniques for extreme environment such as critical nuclear power plant failure or space exploration.

Growth and search for new inorganic single crystal scintillators for nuclear medicine and radiation detectors

• Crystal growth by several techniques such as Czochralski method(Cz), Micro-pulling-down(μ-PD) and so on.
• Developed and modified growth process focused on specific characters for initial materials and purity, dimensions, optical homogeneity, crystallographic defects.
• Much interests in developing new scintillation materials which can be used for x-ray, γ-ray detection, medical devices, nuclear physics and so forth
