At the Nutrition Initiatives & Community Health Equity (NICHE) lab at UT Southwestern Medical Center, our work aims to identify strategies that promote food security and food equity in under-resourced communities by increasing access to nutrient-rich foods and making healthy choices easy and attainable for all families.

During my 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 of my 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, we are aiming to identify preferences for nutritious no-prep, ready-to-eat meals and other nutrition intervention strategies among people that use food pantries. Previous research indicates people that visit food pantries have a desire for healthier foods that are easy to prepare and eat, given physical limitations, time constraints, and/or other barriers that make it challenging to prepare meals. We think nutritious no-prep meals may be one solution, but as a community-engaged research team, we want to know what people actually think about them and if there are other nutrition strategies they prefer.
