Eun Seong Hwang is a professor of Department of Life Science at the University of Seoul. Before joining UOS in 1997, professor Hwang worked at Yale University as a research associate studying the role of human papillomavirus in cervical cancer. After he came back to Korea at 1994, he worked at Samsung Biomedical Research institute as a senior researcher developing gene therapy protocols for human cancers. Although he still has interest in thesee fields of life science, he is currently working on cell biology of aging. At 2000, he started to publish papers on cellular senescence, and since then, his lab is heavily focused on this subject as well as the role of mitochondria in aging at cellular level. His research puts great emphasis on fundamental cell biology trying to understand the basic phenomena related to aging. “Senescence-associated β-galactosidase is lysosomal β-galactosidase” which has been cited 270 times by 2014, is one typical product of such research effort. His lab, the lab of Tumor virology and Cellular Senescence, has raised near 20 masters and Ph.Ds. by 2013. The lab has been maintaining couple ofl master course students and similar number of Ph.D students for years, and now is leading the nation for leading edge research on cellular senescence and mitochondria biology.

Professor Hwang is also active academcally and socially. He has worked as Dean of Research Affairs and the President of UOS Industry Cooperation Foundation of the University of Seoul. He established systems to promote research ethics and morale of graduate students. He also served as president of the Korean society for gerontology and promoted aging research in the nation. He also is actively engaged in education of research ethics by giving lectures and counselings to students and editors of domestic as well as foreign journals.
