Research Statement:

I am most interested in learning about factors that motivate decisions regarding food choices and lifestyle behaviors. Understanding this decision-making helps in the development of interventions designed to promote behavior change.

Research Areas:

  • Nutrition and sports performance
  • Factors that influence food choice behavior
