Dr. Angela Poole is an assistant professor of Molecular Nutrition in the Division of Nutritional Sciences. The overarching goal of her research group is to modulate the interactions between host factors, dietary intake, and oral and gut microbes, to prevent and manage diseases. She earned her Bachelor of Science degree in engineering and applied science from Caltech. Afterwards, she was a research associate in a nutrition lab that studied the genetics underlying macronutrient preference using a mouse model. She earned her PhD in genome sciences from the University of Washington in Seattle in the laboratory of Dr. Leo Pallanck. Afterwards, she was a postdoctoral research associate in the laboratory of Dr. Ruth Ley. Finally, she joined the faculty of the Division of Nutritional Sciences at Cornell University with a burning interest in precision nutrition.
Precision nutrition refers to the quest to determine dietary recommendations for each individual to help them live their best (healthiest) life. Over the years, nutritional scientists have observed that people react differently to the same food. For example, some people’s blood glucose will rise higher if they eat ice cream than if they eat bananas. Surprisingly, for other people, that may not be the case. Which category do you fit into? How do we determine that??? The reasons for this variability are believed to include genetics and gut microbiota. Understanding all of the factors that affect this variability will enable us to make personalized recommendations about what each person should eat to avoid developing conditions such as type 2 diabetes, hypertension, and obesity.
Our goal is to elucidate the interactions between host genetics, dietary intake, and gut microbes in order to benefit host health. Our current projects focus on (1) optimizing dietary fiber intake to prevent diabetes and hyperlipidemia and (2) identifying factors underlying pathogenic biofilm formation in the mouth. Our research is interdisciplinary; we combine knowledge from genetics, nutrition, physiology, microbiology, and computational biology. Our findings could help to develop a systems biology approach to precision nutrition to assist in treating metabolic disorders or decreasing disease risk.
