At the Nutrition Initiatives & Community Health Equity (NICHE) lab, our work focuses on identifying and developing effective multi-component food retail and charitable food system interventions that increase access to nutritious options in under-resourced communities and encourage healthy choices.

During a postdoctoral fellowship at the University of Texas at Austin, my colleagues and I identified barriers and facilitators of fruit and vegetable consumption in Eastern Travis County, as well as the differential impacts of COVID-19 on household food security and parent food purchasing. I finished both graduate degrees at the University at Buffalo, State University of New York. Throughout my doctoral studies, I worked in the Division of Behavioral Medicine where we developed a grocery-shopping intervention for parents interested in buying healthier food for their families using the NIH Stage Model of Behavioral Intervention Development to create an ecological momentary intervention delivered to parents smartphones. 

Currently, the NICHE lab aims to 1) develop effective food retail interventions for areas with limited access to food, 2) identify the impact of nutritious no-prep meals, meal kits, and complementary nutrition intervention strategies developed with and for people that use food pantries and safety-net clinics, and 3) identify strategies to curtail weight regain after patients stop taking GLP-1 Receptor Agonist (RA) medications for weight loss.
