    Biography
    • Sei Kwang Hahn is the Seok Cheon Endowed Chair Professor in the Department of Materials Science and Engineering, and an adjunct professor in the School of Interdisciplinary Bioscience and Bioengineering at Pohang University of Science and Technology (POSTECH). He obtained his B.S. (1991), M.S. (1993) and Ph.D. (1996) in the Department of Chemical and Biomolecular Engineering at Korea Advanced Institute of Science and Technology (KAIST). As the youngest Ph.D. at LG Chemical Group in 1996, he started his research for the commercial development of the sustained release formulation of hGH under the trade name of Declage?. After that, he did his post-doctoral research with Prof. Allan Hoffman in the Department of Bioengineering at the University of Washington for 2001-2002. He worked at the Hoffman-La Roche group, Chugai Pharmaceutical Co. in Japan for 2002-2005. After joining at POSTECH in 2005, he worked as a consultant for Johnson & Johnson in New Jersey in 2008, an associate visiting professor at Harvard Medical School and Massachusetts General Hospital for 2012-2013, and a visiting professor at Stanford University for 2019-2020.

    Research Topics - Biomaterials for Nanomedicine

    The convergence of recent advances in nanotechnology with modern biology and medicine has created the new research domain of nanobiotechnology. The use of nanobiotechnology in medicine is termed nanomedicine. Nanomedicine research includes targeted cancer therapies, localized drug delivery, improved cell material interactions, the development of diagnostics for rapid monitoring, scaffolds for tissue engineering, and gene delivery systems. Successful research and development in nanomedicine where ultimately patients can benefit from these new technologies require the interaction of a multitude of disciplines including material science and engineering, cellular biology and clinical translational research.
