Dr. Ellis’s research interests include nutritional influences on changes in body composition with aging. She recently completed an NIH-funded randomized, double-blind, placebo-controlled trial that aimed to determine whether dietary supplementation with an amino acid cocktail (Juven; Abbott Laboratories) would affect body composition, quality of life, and vascular endothelia function in healthy older adults. Dr. Ellis has also worked with other researchers on dietary and exercise interventions for community-dwelling older adults.
