Thesis adviser: Dr. Diomedes Logothetis

 

Research interests:

Junghoon will study the regulation of ion channels by cellular constituents — namely three-dimensional molecular interactions between proteins and lipid components that control the flow of ions across cell membranes. Studying these transmembrane proteins and their intercellular interactions will further our understanding of mechanisms that underlie various physiological processes, such as the contractions of our hearts, the release of hormones from multiple endocrine and exocrine glands and, most notably, the rapid electrical communication between our neurons. Understanding the interactions at the molecular level is critical if we are to try to develop therapeutic approaches to steer the interactions away from disease conditions into physiological conditions.

Personal bio:

Junghoon was born in Seoul, South Korea and immigrated to the United States when he was seven years old. He graduated from Thomas Jefferson High School for Science and Technology in Arlington. He attended the University of Virginia, majoring in biology, and completed M.S. requirements in physiology and biophysics as a graduate student at VCU prior to enrolling in the VCU School of Medicine as an M.D./Ph.D. student. Having lived in the Richmond for the past three years, he has developed a penchant for its historic landmarks and a number of good restaurants.
