Research Interests

Dr. Shin's lab is interested in how the brain controls metabolism and nutrient partitioning as well as the long-term regulation of body weight and appetite. The main research project aims to understand the role of insulin action in the brain in regulating branched-chain amino acid (BCAA) metabolism and how this central control can contribute to glucose homeostasis by using molecular, pharmacological, transgenic, surgical, and integrative physiological approaches.

Other ongoing research projects:

  • Association between Type 2 diabetes and Alzheimer's disease
  • Effects of Roux-en-Y gastric bypass (RYGB) surgery on appetite, hedonics, and reward control and the underlying mechanisms
  • Understanding how nicotine affects blood glucose
