After my doctoral training in Pusan, South Korea, I joined the laboratory of Dr. Debbie Thurmond at Indiana University, initially as a postdoctoral fellow (American Heart Association-funded fellow), and subsequently was promoted to Assistant Research Professor in the department of Pediatrics at Indiana University. For past twelve years, I have built a long history of research in the biomedical sciences, predominantly in the area of diabetes. My main research focus has been on SNARE (Soluble NSF Attachment protein REceptor) proteins which play essential roles in cellular exocytosis and their binding partners, which are involved in the mobilization and trafficking of intercellular granules such as insulin granules in the pancreatic islet beta cells, as well as GLUT4 containing vesicles in the skeletal muscle and fat.

I have expertise in performing pre-clinical in vivo studies using animal models of Type 1 and Type 2 diabetes, such as diabetic mouse models, tissue specific transgenic and classic/conditional knockout mouse models. Recently, I was funded as an independent investigator through a Showalter Trust Grant from Indiana University in order to study new promising biomarker for treatment of type 2 diabetes. In addition, I obtained a clinical research certificate in IUPUI to support clinical studies.

To date, I have published 10 first author manuscripts in journals such as Cell Metabolism, Journal of Cell Biology, Diabetes, JCEM and JBC with an additional 17 co-author manuscripts.
