Prior to coming to Cleveland Clinic in 2010, she was at the Medical College of Georgia for 17 years where she was an associate professor and the director of surgical nutrition services in the Department of Surgery. Dr. Cresci conducts nutrition research, both laboratory and clinical. She mentors the staff dietitians with their clinical research projects as well as chairs the Center for Human Nutrition Research Committee. She also is the nutrition thread director for the Cleveland Clinic Lerner College of Medicine. Dr. Cresci’s research program focus involves both clinical and basic science experimental designs studying the gut microbiome and its fermentation and metabolic byproducts during health and disease.
Dr. Cresci has routinely been recognized for her excellence in research and clinical practice. Most recently, she was the recipient of the 2025 Peggi Guenter Excellence in Clinical Practice Award from the American Society for Parenteral and Enteral Nutrition (ASPEN).
My research program focuses on the gut microbiome and investigates how its disruption and associated organ pathology may be resolved through nutritional targets and therapeutics. My research utilizes in vitro, in vivo, and human samples in various experimental models and use molecular biology approaches to test our hypotheses.
