Richard A KetchamAssociate Dean, Jackson School of Geosciences
My research spans a wide range of geological problems, with a common thread being developing computational methods to address all stages of the scientific process, from data acquisition and processing to information mining to numerical modeling. I have two primary research areas. One is the application of high-resolution X-ray computed tomography to a diverse spectrum of disciplines, including paleontology, petrology, hydrogeology, structural geology, economic geology and planetary science. The other is theory and practice of apatite fission-track (AFT) thermochronology, and thermal history inversion from AFT, (U-Th)/He, and vitrinite data. I am putting together a state-of-the-art fission-track lab indended for both experimental and field-problem-oriented work.
Other current research interests include numerical depiction of diffusion-controlled crystal growth during prograde metamorphism on geological time scales, and characterizing the thermal structure of continents.
I am always looking for motivated students, especially quantitative and creative ones who are not afraid to do something totally new.

My research is focused on using low temperature thermochronometers such as apatite fission track, and apatite and zircon (U-Th/He) to explore unroofing styles of metamorphic core complexes. Specifically I am attempting to determine if displacement during the evolution of unroofing changes from low angle detachment faulting to high angle normal faults. My two field areas are the Harcuvar Mountains in western Arizona and the Santa Catalina-Rincon Mountains in southeastern Arizona.

I am currently pursuing my PhD under the supervision of Daniel Stockli. My research combines geochemistry, mineralogy and plate tectonics to better understand how minerals form, water-rock interactions, and the thermal and temporal evolution of ocean-continent transitions. I am developing a method that uses magnetite to date serpentinites in order to better understand how continents break up to form oceans. My research interests broadly involve novel geo/thermochronology techniques with applications to tectonics.
