I combine geo- and thermochronometric dating techniques with field work, and petrologic and structural analysis to investigate the evolution of the Earth’s crust and lithosphere. I use these techniques to unravel the mechanisms, including tectonics, climate, and mantle processes, that drive lithospheric and surface evolution.
My research has focused on developing the titanite (U-Th)/He thermochronometer, and applying this tool, in combination with apatite and zircon (U-Th)/He dating, to resolve the long-term time-temperature history of Southern Africa. Together, these thermochrometers can help reconstruct episodes of burial and erosion that are otherwise missing from the geologic record. I am actively investigating the post-orogenic exhumation of the Appalachian Mountains.
If you can reconstruct the time-temperature history of an area, you can deduce topographic and land surface evolution and better assess how/why it happened.
Exit Glacier, Seward Alaska
A well-deserved break in Rocky Mountain National Park, Colorado with Bowdoin student researchers after a successful (U-Th)/He analytical session at CU TRaIL
11.19.19 - New manuscript is out! Mesoproterozoic burial of the Kaapvaal craton, southern Africa during Rodinia supercontinent assembly from (U-Th)/He thermochronology, available at EPSL. We identify for the first time a major reheating (>130C) event, consistent with widespread burial (>3.7 km) across much of southern Africa during supercontinent Rodinia collision!
9.20.19 - Check out new work on the post-orogenic exhumation of the Appalachian Mountains at GSA in Phoenix!
7.10.18 - I had a great time defending my thesis "Bridging high and low temperature thermal histories across the Kaapvaal craton, southern African from advances in titanite and zircon (U-Th)/He thermochronology" and am excited to begin a new position as a visiting faculty member at Bowdoin College
4.26.18 - New manuscript is out! Deciphering a 2 Gyr-Long Thermal History From a Multichronometer (U-Th)/He Study of the Phalaborwa Carbonatite, Kaapvaal Craton, South Africa, available at G-Cubed.
12.15.17 - Great session at AGU "Applications of Thermochronology to Understand Crustal Systems" - sincere thanks to all who participated and attended!
6.19.17 - Summer internships at UNAVCO are all underway! I'm thrilled to help facilitate these exceptional student programs and organize CO field trips and skills and communication seminars!
3.20.17 - New manuscript is out! Influence of radiation damage on titanite He diffusion kinetics, available at GCA. We show radiation damage affects the temperature sensitivity of titanite (U-Th)/He dating.
