Research Interests and Expertise

Dr. Ivy conducts both basic and applied research in the areas of metabolism, nutrition and human performance.  His research has provided the underpinning for many practical and conceptual advances in our understanding of how muscles work and how nutritional supplementation can improve exercise performance.  He has also pioneered our understanding of how timing and type of nutrient intervention affects the ability of the body to recover and adapt to exercise training. His current research is designed to understand the role of specific amino acids in metabolic regulation.
