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 investigating the effects of millennial-scale
geomagnetic variability on CN production rates in time and space. 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.
