Research Interests

  • Regulatory Toxicology – development of human health-based air standards and ambient air quality criteria important in regulating industrial emissions into the air.
  • Toxicities and pathologies associated with occupational and environmental exposures to chemical substances.
  • Developmental Toxicology – perinatal exposures to environmental chemicals as determinants of chronic adult-onset pathologies and diseases (i.e. neurological).

Previous Research Interests:

  • Expression and regulation of placental transporters relevant to fetal protection against endogenous and exogenous substances.
  • Molecular mechanisms underlying the Developmental Origins of Adult Diseases hypothesis.
