My research is quite broad but key central themes are low-temperature geochemistry, radiometric dating, and paleoenvironmental reconstruction, focused largely (but not entirely) the Cenozoic. My students and I have been lucky enough to work all over the world on these topics, including the western USA, central Asia, Ethiopia, southern South America, and Turkey. On a few recent projects I also overlap with archeologists and anthropologists.
My students and I do most of our analytical work in the Environmental Isotope Laboratory run by Dave Dettman, and the Accelerator Mass Spectrometry (for 14C dating) headed by Greg Hodgins. Take a look at my CV if you want the full picture of my research and that of my students.
