Program Focus

I am currently working on using more informative measures of ‘food poverty’ in evaluating how well individuals are reaching nutrition targets, to what extent recent revisions in the SNAP program have helped, and to what extent there are differences across socioeconomic and demographic groups. I also continue to work on the many implications of time constraints on nutrient intake and diet quality.
