Martin M. Shafer PhD
Dr. Shafer is a Senior Scientist with the University of Wisconsin-Madison State Laboratory of Hygiene (WSLH). He is an environmental biogeochemist, working at the interface of chemistry, biology and toxicology. He serves as research lead at the Environmental Health Division of the WSLH, directs the WSLH Trace Element Research Group, and oversees Quality Assurance for the National Atmospheric Deposition Program (NADP). His PhD is from the University of Wisconsin-Madison Environmental Chemistry & Technology Program, in Environmental Chemistry. His research program addresses the cycling of metals and emerging contaminants in aquatic, biologic, and atmospheric systems with a focus on the interface of environmental chemistry and human health. Studies focus on the interrelationships between trace element speciation and biological effect and element/species source delineation using elemental and isotopic fingerprinting. He is an expert in the analytical chemistry (particularly plasma mass spectrometry and electrochemistry) of metals in clinical and environmental matrices and helped develop many of the clean sampling and analytical approaches for trace elements now used by the scientific and regulatory communities. His research group developed new tools for quantification of the oxidative activity of atmospheric aerosols and has applied this toolbox to address chemical drivers of aerosol-associated toxicity in a large body of publications. Dr. Shafer has been associated with the University of Wisconsin-Madison for over 30 years and has authored or co-authored more than 180 peer reviewed manuscripts.
