Research Interests

My research interests focus on developing methods for using in situ cosmogenic nuclides (CNs) to derive surface exposure ages and/or erosion rates for process-oriented geomorphic studies. I have developed reliable methods for extracting in situ cosmogenic ¹⁴C (in situ ¹⁴C) from quartz, and continue to advance those techniques. Recently, I have been using in situ ¹⁴C to calibrate variations of in situ CN production rates with altitude and latitude. As an outgrowth of that work, I am also applying in situ ¹⁴C in concert with long-lived CNs such as ¹⁰Be, ²⁶Al, and ³⁶Cl to investigate complex exposure scenarios, particularly involving glacial advance and retreat.
