Stephen Kuehn is an Associate Professor of Geology and Director of the CU Electron Microprobe Laboratory at Concord University, located within the College of Science, Mathematics, and Health. His research focuses on tephrochronology, particularly using volcanic ash layers for chronological and environmental studies. He has conducted fieldwork in locations such as Newberry Volcano (Oregon), Alaska, and Canada's Yukon region, emphasizing cryptotephra analysis in glacial ice and lake sediments.
Dr. Kuehn holds a Ph.D. from Washington State University and has prior experience as a Visiting Assistant Professor at Washington and Lee University and a Post-Doctoral Research Fellow at the University of Alberta. His technical expertise includes electron microprobe analysis, ICP-OES, and the development of standardized analytical protocols for volcanic glass characterization.
His research spans applications in Quaternary geology, climate change, archaeology, and paleoseismology. He actively promotes data standardization through initiatives like the Tephra Information Portal (TIP) and collaborates internationally to improve tephra data interoperability and accessibility.
Dr. Kuehn’s lab at Concord University integrates advanced microanalytical instrumentation into undergraduate education, providing students with hands-on experience in geochemical analysis and field-based research. He has published extensively on tephra correlation methods, volcanic eruption histories, and paleoenvironmental reconstructions.
