PhD in Nutrition Biology investigates how nutrients affect biological systems at the molecular, cellular, and organismal levels. The program, which typically lasts 3-5 years, integrates courses in biochemistry, physiology, molecular biology, and nutritional science with extensive research. Students investigate food metabolism, the function of vitamins and minerals in health, the effect of nutrition on gene expression, and the mechanisms behind chronic diseases such as obesity, diabetes, and cardiovascular disease. Nutritional therapies for illness prevention may also be developed through research. Graduates are equipped to work in academia, research institutes, healthcare, and the food business, furthering knowledge of nutritional health and its biological impacts.
