Dr. Tae Gyu Pak is a scientist who researches laser-matter interaction using ultra-intense lasers. From his master’s course, he received training at the Center for Relativistic Laser Science (CoReLS) and participated in many experiments such as laser wakefield electron acceleration, and radiation measurements from charged particles. He suggested a new terahertz wave generation mechanism from laser wakefield electron acceleration in the doctoral course. Also developed optical systems to stabilize laser beam pointing in large laser research facilities. Dr. Tae Gyu Pak is currently working as a postdoctoral researcher at the CoReLS. His main research areas are terahertz physics, laser wakefield electron acceleration, and laser-plasma interaction at ultra-high intensity.
