Research Areas

  • Controlled human exposure health effects studies, incorporating chemical exposures and psychological stress to model realistic environmental exposures.
  • Epidemiologic investigations of toxic encephalopathy among workers chronically exposed to solvents and lead with a focus on integrating neuropsychological testing, exposure assessment, and functional imaging.
  • Translational research to examine whether alteration in HPA axis function among lead exposed animals translates to humans chronically exposed to lead
  • International studies based in Thailand to investigate the cognitive and behavioral effects of pesticide exposure in a birth cohort

Research Highlights

  • Discovered a negative dose response relationship between lifetime solvent exposure and functional imaging activation patterns during performance of a working memory task.
  • Demonstrated neurobehavioral performance deficits among workers chronically exposed to solvents
  • Validated a lifetime solvent exposure index with neurobehavioral performance among workers chronically exposed to solvent mixtures
  • Current blood and bone lead alters hypothalamic pituitary adrenal axis function among workers with lifetime exposure
  • Developing behavioral research capacity among public health students at Chulalongkorn University, Bangkok, Thailand.
