Research Statement:

I’m interested in working with students and assisting them in understanding that research is the basis for their professional practice. My research interests are in maternal and child health. Currently, I have two active collaborations which are examining the effects of maternal nutritional status on infant cognitive development and looking at how behavioral economic principles can impact children’s choices in the school lunch program.

Research Areas:

  • Effects of heavy metals on child development
  • Effects of micronutrients on child development
  • Children with disabilities
  • Maternal and child nutrition
