In my lab, we develop and apply computational and theoretical methods with the aim of investigating the chemical and physical problems presented by biomolecular systems. Our current developmental efforts are focused on advancing our ability to simulate protein systems where chemistry is linked with large-scale protein conformational dynamics and corresponding free energy computation. The application part involves, but not limited to, kinases, ATP hydrolases and DNA repair enzymes. These biomolecules present unique set of challenges that present experimental techniques have difficulties to address, while theory can provide detailed understanding at the atomic level.

Kwangho Nam joined the University of Texas at Arlington in Oct 2017. He was born in Korea and received a bachelor’s and master’s degree from the Department of Agricultural Chemistry at Korea University, Seoul, Korea. After serving mandatory military service, he came to the University of Minnesota in 2001 to pursue a Ph.D. in chemistry. During his doctoral study, which was conducted under the guidance of Professors Jiali Gao and Darrin M. York, he has focused on studying chemical reactions in biophysical systems using various computational and theoretical methods and designing new theoretical methods for the modeling of chemical reactions in the condensed phase. After completing his doctorate in 2006, he joined the laboratories of Professors Martin Karplus (Nobel Prize in Chemistry 2013) and Gregory L. Verdine, both of Harvard University, where he learned and developed state-of-the-art simulation methodologies for large scale computer simulation studies. In 2011, he moved to Sweden at Umeå University to begin his independent research career as an assistant professor and research fellow.

AT UT Arlington, his research interest is in the development of novel multiscale QM/MM and free energy simulation methods for accelerated simulations of enzymatic catalysis, protein conformational change and ligand recognition and their application to challenging biological systems to aid to understand their working principles. 

2007-2009. Postdoctoral fellowship from the National Cancer Canter

1992-1995. Honored student scholarships from Korea University

1991.            Student entrance scholarship from Korea University
