Jeong-Ho Kim

Dr. Jeong-Ho Kim

Associate Professor of Biology

(434) 582-2462
Science Hall, Room 150


  • Postdoctoral Research in Molecular & Cellular Biology, Washington University School of Medicine
  • Ph.D. in Microbial Molecular Genetics, University of Wisconsin-Madison
  • B.S., Chonnam National University


Dr. Kim obtained his Ph.D. in microbial molecular genetics from the University of Wisconsin (Madison, WI) and did postdoctoral research in molecular and cellular biology at Washington University School of Medicine (St. Louis, MO). He was a faculty member at the University of Southern Mississippi and an Assistant Science Advisor to the NIH-sponsored MS-INBRE (Hattiesburg, MS). He joined Liberty after teaching at the George Washington University School of Medicine and Health Sciences (Washington, DC).


Dr. Kim’s research interests are largely directed toward understanding how environmental cues interact with genetic components to regulate cell growth and development.  He is particularly interested in learning how nutrients and metabolites transduce information to cellular effector functions and how dysregulation of this process leads to metabolic diseases, such as obesity, type 2 diabetes, and cancer.
