Dr. Gray is an associate professor and the interim lead in Nutrition and Dietetics MPH concentration. She is a registered dietitian in training (Credential ID No. 959398) and received her PhD in Behavioral Nutrition from Columbia University. Dr. Gray’s research focuses on developing and evaluating obesity prevention and nutrition education intervention programs, especially for children and adolescents. Since she joined USF in 2017, she has conducted several studies as a principal investigator (PI) including a preliminary study to assess dietary intakes, mealtime behaviors, and parental views on eating behaviors of children with autism spectrum disorder (ASD) and a community food assessment project to examine food access and environment in low-income neighborhoods in East Tampa. Her current research projects include nutrition education interventions for children with ASD, Hispanic children with obesity and their parents, and pediatric cancer survivors. Dr. Gray is the PI of a R21 grant (R21HD106182) funded by NIH/NICHD that aims to refine and test the feasibility and preliminary efficacy of a nutrition intervention for children with ASD and their parents through the Early Intervention Services. She serves as a Co-I for a multi-site NIH/NCI R01 nutrition intervention clinical trial (PI: Stern, R01CA240319) overseeing the study’s dietary intake data collection and management, and also serves as a Co-I for a NIH/NICCIH R34 pilot mindful eating intervention clinical trial (PI: Stern, R34AT010661) and a supplementary project (MPI: Redwine & Stern, R34AT010661-01S1) to assess COVID-19 testing and vaccine uptake attitudes and behaviors among rural Latino migrants in Southwest Florida. She is actively involved in local, national, and international nutrition professional societies. She serves as the Chair of the Research Division of the Society for Nutrition Education and Behavior (SNEB) and the Secretary of the Journal Committee of SNEB. She received a Professional Achievement Award in Community Nutrition from SNEB in 2019 and a Best Article Award from the Journal of Nutrition Education and Behavior where she serves as a member of the Editorial Board. She is a member of the Nominating Committee of the Florida Academy of Nutrition and Dietetics and the Leadership Committee of the USF Urban Food Sovereignty Group.
