Dr. Andrew C. Shin obtained his doctoral degree in Neuroscience at Michigan State University in 2008 and completed his postdoctoral fellowships at Pennington Biomedical Research Center and Icahn School of Medicine at Mount Sinai where he became an instructor with his NIH K01 award. He joined the Department of Nutritional Sciences here at TTU as a Research Assistant Professor in 2016, and he is now appointed as an Assistant Professor in 2019.

Research Focus

Dr. Shin is interested in understanding how the brain controls metabolism and nutrient partitioning as well as the long-term regulation of body weight and appetite and the underlying mechanisms of bariatric surgery. Dr. Shin's research project that was funded by the NIH 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.

His other ongoing research projects include:
1. Association between Type 2 diabetes and Alzheimer's disease
2. Insights on how nicotine (a major constituent in cigarette) affects blood glucose
3. BCAA regulation in heart function

Research Interests

Obesity, diabetes, nutrient metabolism, Alzheimer's disease, heart failure, cancers, gut hormones, appetite-related signals, bariatric surgery, Roux-en-Y gastric bypass (RYGB)
