His lab examines how changes in fat metabolism regulate immune function in childhood/young adulthood through old age. Currently, they are using genetically altered animal models of fat metabolism to mimic an aged immune system and analyze the impact on prostate cancer development and progression and the production of new immune cells. His projects are combining these animal models with dietary factors like changing fat amount (diet induced obesity) and type (omega-3 fatty acids) as well as phytochemicals (resveratrol) to modulate fat metabolism to determine their effects on immune function. The ultimate goal is to identify dietary factors that regulate immunometabolism to improve immune function and subsequent health at various stages of life.
