Mark Krekeler

Mark Krekeler is an Associate Professor at Miami University, affiliated with the Institute for the Environment and Sustainability, Department of Geology and Environmental Earth Science, and the Center for Aquatic and Watershed Sciences. His research focuses on mineralogical and geochemical properties in environmental and synthetic systems, including defense geotechnologies, shale mineralogy, gold/mineral resources, and urban pollution. He holds a Ph.D. in Geotechnical Engineering and Earth Sciences from the University of Illinois at Chicago.

His work combines advanced analytical techniques like transmission electron microscopy (TEM) and scanning electron microscopy (SEM) with field studies in Nevada, the U.S.-Mexico border, and the Midwest. Recent grants include NSF support for geotechnical research and NIJ funding for remote sensing of human materials. He advises graduate and undergraduate students on projects ranging from Nevada gold deposits to urban pollution in Ohio and Puerto Rico.

Key research themes include mineral-catalyst interactions, rare earth element mineralization, and environmental impacts of industrial activities. His publications span environmental geochemistry, forensic mineralogy, and planetary resource studies. He teaches courses in environmental geology, economic geology, and advanced mineralogy, emphasizing field methods and applied geoscience.
