Nathaniel Lifton is a Professor and Associate Head in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. He holds a Ph.D. from the University of Arizona (1997) and a B.S. from the University of California, Santa Barbara (1985). His research focuses on advancing in situ cosmogenic nuclide (CN) techniques for geomorphic and paleoclimatic studies, particularly using in situ 14C to study glacial dynamics, exposure histories, and landscape evolution. He has developed methods for extracting 14C from quartz and olivine, and his work addresses production rate calibration, geomagnetic effects, and multi-nuclide dating approaches.
Professional experience includes roles at Purdue since 2010 and prior research positions at the University of Arizona’s NSF-Arizona Accelerator Mass Spectrometry Facility. His publications span cosmogenic nuclide theory, glacial history, and methodological advancements. Research emphasizes linking cosmogenic data to tectonic, climatic, and erosional processes.
Key contributions include Bayesian isochron methods for glacial chronology, scaling production rates with geomagnetic models, and calibrating altitude/latitude effects on CN production. His work bridges geochronology with environmental science, offering tools to understand Earth’s surface processes over millennial timescales.
