We focus on plant foods and cancer prevention:

  • Dietary modulation of biotransformation enzymes and carcinogen metabolism
  • Development of dietary biomarkers
  • Gene – diet interactions: both nutrigenomic (animal models) and nutrigenetic (in humans)
  • Diet effects on colonic miRNA expression, cancer stem cells
  • Comparison of the effects from intact vegetable feeding versus their purified putative chemopreventive compounds

Expanding interest into obesity:

  • Role of bioactive plant compounds in decreasing obesity-mediated cancer risk
  • Role of plant foods and their constituents in childhood obesity prevention
  • Virtual reality as a means to prevent childhood obesity.
