ENERGY BALANCE &
Research in the Energy Balance and Nutrition Laboratory (EBNL) focuses on the energy mechanisms that contribute to desirable or less desirable weight gain, growth, and nutritional status in infants, children, and adolescents who are healthy, and in those with chronic disease. Since weight status in young childhood affects development and is predictive of adult weight status, the goal of our laboratory is help all individuals reach and maintain a healthy weight.

Jillian Trabulsi, PhD, RD
Shannon Robson, PhD, MPH, RD
Associate Professor, Director of Nutrition Science PhD Program
Carrie P. Earthman, PhD, RD
Professor and Director of Research for the UD Health Nutrition Clinic
Dr. Earthman joined the faculty at the University of Delaware in 2019, after spending much of her academic career at the University of Minnesota. She has been a Registered Dietitian since 1991, when she began her career as an acute care dietitian working in GI disorders, heart and pulmonary failure, HIV/AIDS, cancer, and nutrition support. She went on to earn her MS and PhD in Nutritional Sciences at the University of Illinois and the University of Arizona, respectively.
Graduate & Undergraduate Research Assistants
Adriana Verdezoto Alvarado is a Nutrition Sciences doctoral student from Ecuador. She graduated with a BS in Biology with a minor in Chemistry at Randolph College and an MS in Nutritional Sciences at Arizona State University. At ASU, Adriana worked with minority populations to improve nutrition and physical activity in children and adults. Her research interests include behavioral-based interventions, the home food environment, dietary patterns, and prevention of chronic disease.
Lynn Ferro is a doctoral student working in the Energy Balance and Nutrition Laboratory. Lynn’s research interests are centered around infant nutrition and its connection to the gut microbiota. Currently, Lynn is conducting the First Foods Study to examine the impact that first complementary foods fed to infants have on the microbial communities of the gastrointestinal tract. Prior to coming to the University of Delaware, Lynn received her B.S. in Nutritional Sciences with a concentration in Biomedical and Molecular Nutrition from Michigan State University.
Michelle Delahanty is currently a Research Associate in the Energy Balance and Nutrition Lab. She earned her Master of Public Health in Behavioral and Community Health Sciences, with a certificate in Evaluation, from the University of Pittsburgh in 2019. Her research interests include food security, maternal and child diet/health, and chronic disease management and prevention.
