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
Associate Professor, Director of Graduate Program
Dr. Trabulsi started her career as a clinical dietitian at The Children’s Hospital of Philadelphia (CHOP). After practicing for six years, she went on to earn her Ph.D. in Nutritional Sciences at The University of Wisconsin – Madison, followed by a post-doctoral fellowship in Pediatric Nutrition and Growth at The Children’s Hospital of Philadelphia. Her research interests center upon diet, nutritional status, growth, and energy balance in infants and children who are healthy and in those with chronic disease. She is specifically interested the components of the energy balance equation that contribute to desirable or less desirable growth patterns. Her research has been funded by grants from the National Institutes of Health as well as private foundations and her work is published in peer-reviewed journals.
Shannon Robson, PhD, MPH, RD
Dr. Robson is an alumnus of the nutrition program at the University of Delaware. She earned her MPH in community health education and PhD in Nutrition Science at the University of Tennessee Knoxville, and completed a National Institutes of Health post-doctoral fellowship in Child Behavior and Nutrition in the Division of Behavioral Medicine and Clinical Psychology at Cincinnati Children’s Hospital Medical Center. Her research interests are focused in pediatric weight management and child eating behaviors that impact energy balance.
Carrie P. Earthman, PhD, RD
Professor and Director of Research for the Nutrition Clinic at STAR Health
Dr. Earthman recently joined the faculty at the University of Delaware, 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
Jessica Eosso is currently a doctoral student in the Human Nutrition program. She graduated with a B.S. in Dietetics and Nutrition Sciences from the University of Delaware in 2016 and became a Registered Dietitian after completing her dietetic internship in 2017. Her research interests include diet, nutritional status, and growth in infants and children in relation to later health outcomes. She is specifically interested in the role of mothers in forming infant dietary patterns as well as the infant gut microbiome.
Kaelyn is a Master’s student in the Human Nutrition program and she graduated with a B.S. in Applied Nutrition from the University of Delaware in 2017. Her research interests include diet quality and dietary energy density in relation to weight management and chronic disease. Her future plans include pursuing a doctoral degree in the nutrition field.
Amanda Kopetsky, MS, RDN, LDN graduated from Penn State University with a BS in Nutrition Science. She attended Cedar Crest College for her dietetic internship, spent three years working in SNAP-education at The Food Trust, and worked clinically in acute care. After working for three years, she attended the University of Delaware for her Master of Science degree as a full-time research assistant. Upon graduating with her MS, Amanda spent time in long-term care as well as home, corporate and virtual counseling. Currently, Amanda is back at the University of Delaware as a research assistant completing her Ph.D. in Nutrition. Her interest is in public health and community nutrition with her research focused on the food acquisition pathway and diet quality.
Adriana Verdezoto Alvarado is a doctorate student from Ecuador. She graduated with a B.S. in Biology with a minor in Chemistry at Randolph College and an M.S. in Nutritional Sciences at Arizona State University. She will be a doctorate student in the Human Nutrition program. Her research interests include dietary patterns and energy balance among diabetic and obese populations.
Lynn Ferro is a doctorate student working in the Energy Balance and Nutrition Laboratory. Lynn’s research interests are mainly centered around infant nutrition as well as understanding more about the gut microbiome, both of which she will be investigating further at UD through her research. 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. At MSU, Lynn worked in a nutrition research lab on campus analyzing different strains of Bifidobacterium in mothers and their infant’s stool samples in order to understand the connection between a mother and an infant through the gut microbiome.
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.
Emma Blancher is a currently a junior at the University of Delaware. She is majoring in Health Behavior Science with a minor in Disability Studies. Her future plans to include attending a post-graduate program for accelerated nursing, and plans on working with a nutrition focus. She is interested in how therapeutic diets can improve chronic medical conditions. Emma is hoping to use the information she’s learned in her undergraduate years in her career.
Talia is a sophomore health behavior science major with a minor in coaching science and writing. She is interested in working with adolescents in nutritional health and physical activity. During the school year, she runs cross-country and track while managing the running club’s social media accounts. Talia also write for the university’s independently run student newspaper, The Review. She intends to graduate in 2022 and pursue a Master’s in Public Health.
