Professor Heather Stapleton is an environmental chemist and exposure scientist in the Nicholas School of the Environment at Duke University.  Her research interests focus on identification of halogenated and organophosphate chemicals in building materials, furnishings and consumer products, and estimation of human exposure, particularly in vulnerable populations such as pregnant women and children.  Her laboratory utilizes mass spectrometry, including targeted and nontargeted approaches, to characterize chemical burdens in both environmental samples and biological tissues to support environmental health research. Currently she serves as the Director for the Duke Superfund Research Center, and Director of the Duke Environmental Analysis Laboratory, which is part of NIH’s Human Health Environmental Analysis Resource.
