Educational Background: 
Ph.D., University of Arkansas for Medical Sciences
Area of Specialty: 
  • My laboratory develops model systems to identify microbial and chemical agents that affect pregnancy and development, and we use those models to investigate mechanisms of toxicity and develop therapies for treating adverse effects.

  • Developmental and reproductive toxicology

  • Microbial and chemical risk assessment
Research Interests: 
  • Effects of toxicants on reproduction and development
  • Environmental and microbial risk assessment methodology
  • Effects of pathogens on pregnancy and development
  • In vitro and in vivo models for toxicity testing
