Positions

Overview

  • I graduated from Yonsei University, Seoul, Korea with B.S and M.S degrees in Nutrition and Biochemistry, respectively. I have broad training and extensive experience in area spanning regulation of gene transcription, signal transduction, cell biology, metabolic and vascular animal physiology, and translational studies with an eye towards therapeutic discovery for human diseases. While in graduate school at Iowa State University and during post-doctoral training at Penn State University, I focused on elucidating mechanisms for transcriptional activation. of cAMP responsive element binding protein (CREB) to regulate glucose metabolism in the liver. I received the second post-doctoral training with Dr. Michael Quon in the Diabetes Unit, NIH. Here, I developed deep expertise in signal transduction, particularly related to insulin action and endothelial function. I also gained a more thorough understanding of animal and human physiology and pathophsyiology related to diabetes, obesity, and their cardiovascular complications. After post-doctoral training, I obtained an independent position at the University of Missouri, Columbia. While at Missouri, I expanded my research from basic science to animal physiology and translational research. Since 2010, I have been appointed as a tenure-track Assistant Professor at the University of Alabama, Birmingham (UAB).

    Research Overview

  • My research area focuses on understanding the mechanisms of insulin resistance and endothelial dysfunction. This includes identification and characterization of molecules that are responsible for the saturated fatty acid-mediated inflammatory response in the vasculature that contribute to impairment of insulin signaling and cardiometabolic functions. The research project involves molecular, cellular, and pharmacological tools to investigate physiological roles of eNOS/NO in vasodilation and metabolism. Second research project is to understand the role of vascular autophagy in nutrient metabolism. Since autophagy is one of the essential cellular process in normal and stress conditions, uncovering the roles of vascular autophagy in metabolic disorders will provide additional information to elucidate the relationship between vascular function and metabolism. These projects will help better understanding of physiology and pathophysiology of cross-talk between multiple tissues via vascular endothelium. That being said, we are working on developing pharmacological and molecular strategies to improve public health regarding metabolic disorders.
