Biography and Education


Dr. Gar Yee Koh is an Assistant Professor in the School of Family and Consumer Sciences at Texas State University. Dr. Koh earned her doctorate degree (PhD) in Nutritional Sciences from Iowa State University (ISU), as well as a Master’s in forestry and a Bachelor’s degree in Nutritional Sciences, both from Louisiana State University. She also completed her postdoctoral trainings at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (2015 – 2019) and Citrus Research and Education Center at the University of Florida (2019 – 2020). As part of a multidisciplinary team, her research work aimed to promote gut health and metabolic disease prevention at the cellular and molecular levels.

Dr. Koh’s research focuses on promoting gut health to prevent complications resulting from obesity and other metabolic diseases. Her research has 3 main themes: 1) remodel gut microbiota to prevent obesity-induced gut inflammation, 2) identify and develop new dietary interventions to optimize vitamin D status in people with obesity and diabetes, and 3) investigate the effect of maternal diet on vitamin D metabolism among offspring. Her lab employs a variety of biochemical and molecular techniques, cell culture, rodents, and other in vitro methods to address these health priorities.

Dr. Koh is currently seeking collaborative opportunity in nutrition and gut microbiome, particularly with a focus on obesity and/or diabetes.
