Research

My primary research is to use variety ofbiomarkers for assessing human exposures to environmental chemicals in order to facilitate the identification of risk factors, as well as the formation ofhypotheses for the 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 longitudinalexposure to pesticides via dietaryintakes and its risks by comparing to benchmark doses used by regulatoryagencies.  I am also interested in developing the protein adduct-base biomarker to assess the health effects from exposures to organophospate pesticides.

            I am collaborating extensively with scientists/researchers in the following research projects; 1) children’s longitudinal pesticide exposures with the National Center for Environmental Health Pesticide Laboratory at the Center for Disease Control and Prevention (CDC), 2) pesticide residues in food with Food and Drug Administration regional labs in Atlanta GA and College Park MA, 3) OP-adduct biomarker with Agricultural Health Study, 4) nicotinyl insecticides and bee colonies collapsing disorder with Cornell University, and 5) community-based farmworker housing, exposures and health with Wake Forest University School of Medicine.
