Human Nutrition

Research Interests:
Muscle and protein metabolism, nutritional management in clinical populations

Research Summary:
Our research focuses on clinical nutrition, lean tissue/muscle assessment, and protein metabolism in various clinical populations. We are particularly interested in novel applications to refine protein recommendations with the goal of preserving muscle mass and preventing malnutrition. Our research also aims to develop noninvasive methods to accurately identify the development of malnutrition and monitor changes in muscle mass at the bedside while optimizing nutrition interventions throughout medical treatment. Overall, we are passionate about improving patient outcomes and quality of life in clinical populations.
