Research Interests

I'm interested in light matter interaction – how light energy is absorbed in a target material, how the absorbed energy is converted and transported throughout the target, and how the target material responds to it. These basic questions are important to understand the physical mechanism such as target material damage upon laser irradiation and its mitigation, and to develop useful optoelectric applications such as infrared photodetectors. Previously, I have developed novel laser material processing techniques using laser induced-heating, deposition, and ablation, and also performed optical material characterizations such as Raman and scanning photocurrent microscope.
