Nathaniel Lifton is a professor and associate head in the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. His research focuses on developing methods using in situ cosmogenic nuclides (CNs) to derive surface exposure ages and erosion rates in process-oriented geomorphic studies. He has developed reliable methods for extracting in situ cosmogenic 14C from quartz and continues to advance techniques for using in situ 14C to calibrate variations in cosmogenic nuclide production rates based on altitude and latitude. His work investigates the effects of millennial-scale geomagnetic variability on cosmogenic nuclide production rates over time and space. Lifton applies in situ 14C in conjunction with long-lived CNs such as 10Be, 26Al, and 36Cl to study complex exposure scenarios, particularly involving glacial advances and retreats. He has held several academic positions, including assistant professor at Purdue University and associate research scientist at the University of Arizona.
