Mark and Catherine Winkler Assistant Professor of Environmental Exposure Biology

More pesticides are used on lawns, per acre, than on agriculture. Dr. Alex Lu of Harvard's School of Public Health will be speaking at the February 22 hearings in Concord in support of New Hampshire's HB 495, An Act relative to the prevention of the use of pesticides on the grounds of child day care facilities, schools, and state parks. My primary research is to use variety of biomarkers for assessing human exposures to environmental chemicals in order to facilitate the identification of risk factors, as well as the formation of hypotheses for potential health effects. One of my current research projects is to integrate exposure biomarkers, physiologically based pharmacokinetic model and cumulative risk assessment tools for quantifying children’s longitudinal exposure to pesticides via dietary intakes, and its risks by comparing to benchmark doses used by the regulatory agencies.
