I majored in biotechnology in Yonsei University and chose biology as my second major. After graduation I took part in several experimental projects as a research assistant for 2 years in National Cancer Center and Oral biology laboratory in Yonsei University College of Dentistry. After 4 years of studying in Yonsei University College of Dentistry, I worked in Department of Orofacial pain & Oral Medicine, Yonsei University Dental Hospital as an intern and resident, learning about dental medicine and orofacial pain. As a result of the attention and the effort, I was privileged to have an oral presentation in conference of Korean Academy of Orofacial Pain and Oral Medicine and won the grand prize. Now I am fellowship doctor in Department of Orofacial pain & Oral Medicine, Yonsei University College of Dentistry.
