Susan Carnell, Ph.D.
Assistant Professor of Psychiatry and Behavioral Sciences
Research Interests: Neuroimaging; Child obesity; Obesity; Eating behavior; Eating disorders; Appetite; Genetics; Parent feeding; Stress; Gut hormones
Susan Carnell received her BA in Experimental Psychology from the University of Oxford and completed a PhD in Health Psychology focusing on parental feeding style and children's eating behavior at University College London. She was then awarded an ESRC/MRC Interdisciplinary Post-doctoral Research Fellowship, in which she used behavioral genetic data from a national twin study to examine genetic and environmental influences on child appetite and obesity. Following this, she moved to the New York Obesity Nutrition Research Center at Columbia University where she spearheaded studies of circadian and stress-related variation in neural (fMRI) and hormonal responses to food and food cues among obese and lean adults with and without binge eating. Here she was also awarded a K99/R00 Pathway to Independence award to investigate neural responses to food cues in obese and lean adolescents varying in familial and genetic obesity risk. In 2013 she became faculty at the Division of Child & Adolescent Psychiatry, where she leads a program of research investigating eating behavior and obesity throughout the lifespan, including neuroimaging studies in infants, children and adolescents.

Research & Publications
Why do some people become obese while others remain lean? We propose that individuals differ in appetite-related characteristics that manifest early in life, show genetic influence, and interact with environmental factors (e.g. family feeding practices) to predict eating behavior and weight.
To understand more about the character and origins of these characteristics (e.g. food cue responsiveness, satiety sensitivity), my lab uses a range of methods including behavioral tests, self- and parent-report questionnaires, genotyping, hormonal assays, and neuroimaging techniques (fMRI, MRI, PET).
Ongoing research projects include investigations of appetite and body weight in infants, children, adolescents and adults, including studies of eating behavior in anorexia nervosa, attention-deficit hyperactivity disorder, cystic fibrosis, and individuals undergoing bariatric surgery.
We are conducting a research study in children (4-13 y old) and their biological mothers. The study involves two visits for 3-4 hours each, and includes fMRI scan (child only), body composition measurements (height, weight, waist), questionnaires, computer tasks, buffet meals, and saliva collection. Compensation is up to $125, plus $10 travel costs for each visit. If interested, please call 410-955-5099 or email Appetite@jhu.edu.
