Adjunct or Visiting, Environmental Health
My research has focused on developing quantitative dose-response methods for regulatory risk assessment of health impacts of chemical mixtures. Important achievements include developing a modified interaction-based Hazard Index for mixture risk assessment, and a dose-severity approach for noncancer dose-response modeling, both have been implemented by US EPA. Related interests include toxic interactions of environmental chemicals with environmental conditions such as those from climate change: heat and wildfire smoke.
1980-2006 U.S. Environmental Protection Agency, National Center for Environmental Assessment. Led research program on health risk assessment of chemical mixtures. Details with EPA Homeland Security Research Center, and with EPA Region 9 in San Francisco. Two silver medals and four bronze medals for mixture risk assessment methods and cumulative risk assessment guidance.
