I graduated from Chonnam National University Medical School and completed residency in Internal Medicine at Chonnam National University Hospital and fellowship of Rheumatology at Hanyang University Hospital. From 2002 to 2005, I conducted a joint study with Prof. Cornelia M. Weyand and Prof. Jorg J. Goronzy as a postdoctoral research fellow at the Institute of Rheumatology and Immunology at Mayo Clinic and Emory University. I have been working as a Professor of Rheumatology at Chonnam National University Medical School, and I am currently the Head director of Chonnam National University Bitgoeul Hospital. I have mainly studied innate immune cells, such as natural killer (NK) cells, natural killer T (NKT) cells, and mucosal-associated invariant T (MAIT) cells in various immune diseases. Innate immune cells are known as primary immune cells in the immune system, and they have the primary defense function when various virues and bacteria invade into our body. In addition, innate immune cells play an important role for controlling or suppressing the development of various cancers. I found that innate immune cells were dysfunctional in rheumatic diseases. In addition, my research is not only limited to arthritis and autoimmune diseases, but there are excellent research results in various infectious diseases, trauma, and malignancy.
