Dr. Sohn is from South Korea and received his MD and PhD from Seoul National University College of Medicine in Seoul, South Korea. Dr. Sohn first came to UT Southwestern in 2009 as a postdoctoral researcher to study the in vivo function of hypothalamic neuronal activity. During this time, he worked on the function of serotonin and melanocortin receptors in neuronal control of appetite and metabolism. Dr. Sohn is currently an assistant professor of biological sciences in Korea Advanced Institute of Science and Technology (KAIST), where he continues to study neuronal control of homeostasis. He came back to UT Southwestern as a visiting faculty member. Dr. Sohn’s interests outside the lab include his family, working out and travel.
