Heather joined MAS in 2001 as a student and continues as a regular member. She has served in the Society as Director, Secretary, and MicroNews editor, and is currently International Liaison. She earned a Bachelor’s Degree in Geology at Mount Union College, Alliance, OH (2000) and a Master’s Degree in Geochemistry from the Colorado School of Mines (2005). She specializes in microanalysis of rocks, minerals, and other materials from a wide variety of applications. As Director of the Denver Microbeam Laboratory, an analytical facility operated by the USGS Mineral Resources Program, she is responsible for a) developing and improving methods of electron beam microanalysis techniques as needed to address a broad range of earth science issues, b) work with colleagues to interpret the microanalysis data in the context of geologic processes, c) instruct scientists in the theory and operation of electron microbeam instruments and assist in data reduction, and d) development and maintenance of software for data reduction and operation of the electron microprobe and scanning electron microscope. While most of her research supports the Energy and Minerals USGS Mission areas, her knowledge of microanalysis and electron beam based instruments and software has allowed her to tweak existing methods, or create new methods to help collaborators in the Water, Climate and Land Use, Natural Hazards, and Ecosystems mission areas, and other Federal and State agencies such as US EPA, EPA National Enforcement Investigations Center (NEIC), Center for Disease Control (CDC), Mine Safety and Health Administration (MSHA), US Public Health Service, FEMA, US Department of Justice, NASA, US Air Force, US Army, US Department of State, Port Authority of New York and New Jersey, State of California, and the State of Colorado.
