Received the Ph. D degree in Information Display from Kyung Hee University (Seoul, Korea) in 2014. Researched on oxide semiconductor-based thin-film transistors (TFT) for transparent and flexible display applications the Ph. D course. Also worked on projects involving the development of digital X-ray detectors. Joined the department of Information display at Kyung Hee University as an assistant professor in 2015. Current research includes the design of novel TFT structures for device performance and stability improvement and the development of perovskite semiconductor-based thin-film transistors and a CNT-based multi X-ray source.
