  • My research involves the synthesis of sedimentary, stratigraphic, geochemical, and paleontological data to better understand Earth’s history. As a scientist working for the Wisconsin Geological Survey, I pursue research projects that produce objective scientific information about the geology of Wisconsin in order to support informed decision making by Wisconsin’s citizens, government, businesses, and industry.
