Research is focused on studying the relationship between geological factors and health problems in humans and animals, with a focus on exposure to minerals, inhalation of ambient and anthropogenic mineral dusts and volcanic emissions.

Research interests include:

  • Asbestos, and asbestos-related diseases including health effects from exposure to asbestos-containing materials (ACM), mineral dusts (MD) and volcanic ash (VA).
  • Us of advanced analytical methods for characterizing ACM, MD and VA, including scanning electron microscopy (SEM); transmission electron microscopy (TEM), and polarized light microscopy (PLM), x-ray diffraction (XRD) and/or energy dispersive (ED) X-ray fluorescence spectrometry (XRF).
  • Metrological challenges quantifying asbestos in bulk building materials, ambient, indoor and workplace air, drinking water and settled dust. Harmonizing asbestos measurements across different laboratories using different methods.
  • Exposure to atmospheric nanoparticles and associated impact on human health

Associated Researchers

Christopher D. Palmer, Ph.D.

Christopher D. Palmer, PhD

Deputy Director, Clinical Trace Elements Laboratory

We develop and maintain robust ICP-MS methodologies to support both human biomonitoring studies and emergency preparedness.

Patrick J. Parsons, PhD

Director, Division of Environmental Health Sciences

We study human exposure to toxic metals/metalloids (biomonitoring) and long-lived nuclides (radiobioassay); and develop novel speciation methods by coupling LC and GC to ICP-MS, while using portable XRF for field-based studies.
