I am an expert in mid-low temperature thermochronometry. I combine dating tools with fieldwork, structural relationships, and detailed petrography to investigate the evolution of the Earth’s crust across spatial, temporal, and thermal scales. I use these techniques to unravel the mechanisms, including tectonics, mantle processes, and seismicity 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 syn- and post-orogenic exhumation of the Appalachian Mountains using detrital zircon (U-Th)/He thermochronology and apatite (U-Th)/He thermochronology.
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.
I firmly stand with the Black Lives Matter movement, and am committed to increasing the participation and success of Black, Indigenous, and people of color in the geosciences.

I am a participate of the URGE program and encourage all those working in the geosciences to take advantage of this valuable curriculum and resource!
URGE's primary objectives are to (1) deepen the community’s knowledge of the effects of racism on the participation and retention of Black, Brown, and Indigenous people in Geoscience, (2) draw on existing literature, expert opinions, and personal experiences to develop anti-racist policies and strategies, and (3) share, discuss, and modify anti-racist policies and strategies within a dynamic community network and on a national stage.

3.17.20 - Undergraduate student researchers Luke Basler and Cameron Markovsky were accepted into their top choice grad programs! And Luke's FIRST AUTHOR paper was just accepted at the journal Geosphere.
7.27.20 - "With Virtual Reality, group member Thais Carrillo '23 (Bowdoin College) Opens Famous Maine Geology Site to All" in an effort to create a physically inclusive field trip! Can't wait to share our progress at Virtual GSA 2020 and pilot the field trip this fall at Bowdoin College.
6.30.20 - Check out our session at the annual GSA meeting "T20. Topographic and Lithospheric Evolution of Elevated Continental Passive Margins" - abstract submission is open!
12.15.19 - Check it out - Bowdoin Intro Geology students engage the community with great demonstrations and presentations "How to Teach Geology with Jell-O and Chocolate Syrup"
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.
