My research supports exposure assessment as a part of risk assessment associated with human health protection. I have conducted studies of exposure and potential for exposure to:
  • Arsenic in private water supplies,
  • E. coli, as an indicator of fecal contamination in water,
  • Leptospira, as a result of changes in land use in Hawaii, and  
  • Cryptosporidium.
