Research Focus
Dr. Ricki J. Colman's lab at the University of Wisconsin-Madison focuses on understanding how specific dietary changes can promote healthy aging and combat age-related diseases, particularly obesity and diabetes. Through research involving dietary amino acids, the lab aims to discover new nutritional interventions that can help restore metabolic health in older populations. Their work has important implications for improving the healthspan of aging individuals.

Research Aims
5AIM 01Test the effectiveness of amino acid-restricted diets in reversing obesity in older mice.
AIM 02Investigate the molecular mechanisms behind dietary amino acid interventions through transcriptomic studies.
AIM 03Evaluate the impact of specific dietary modifications on insulin sensitivity in mice and primates.
AIM 04Assess the long-term effects of altered amino acid consumption on body composition in aged populations.
AIM 05Explore the role of the microbiome in response to dietary changes.

Career totals from OpenAlex, compared against labs that share a department. A department spans everything from one paper to tens of thousands, so bar heights are on a log scale — otherwise the largest lab would flatten every other bar to a line.
