Whitney BehrAssistant Professor, Department of Geological Sciences, Jackson School of Geosciences
My research focuses on the mechanics and kinematics of deformation at plate boundaries and spans a wide range of spatial and temporal scales. I examine the geomorphic expression of young, active faults, and I study older remnants of deep-seated ductile shear zones exhumed from greater depth within the lithosphere. I apply a wide range of field, structural/microstructural, geochronologic and analytical methods. For more detail, feel free to check out the Behr Research Group web page.

Kyle Ashley is a Jackson School of Geosciences Distinguished Postdoctoral Fellow working with Prefessor Whitney Behr. Kyle earned his BSc at SUNY Potsdam, his MSc at the University of Vermont, and his PhD at Virginia Tech. His research is focused on the evolution of metamorphic and igneous systems, applying pseudosection analysis, petrographic assessment, geochronology, and conventional and unconventional thermobarometric techniques to unravel changes in a rock’s pressure, temperature, fluid, mineralogy and deformation across time. Lately, Kyle has been studying the theory and application of trace element thermobarometers (e.g. Ti-in-quartz), as well as making advances in utilizing included minerals in rigid hosts for thermobarometry purposes with the application of elastic theory. He is currently studying rocks from Scotland, Himalayan Mountains (India, Nepal, and Bhutan), Greece, northern Appalachians, the Adirondack Mountains, Australia, Colorado, Lesser Antilles (Caribbean), and Madagascar.
Nicholas J Dygert
Nick earned a Bachelor of Science at the University of Rochester and his PhD at Brown University. His research focuses on understanding the physical and chemical evolution of the terrestrial and lunar mantles using experiments, numerical models, and field studies. Subjects of active research include an experimental study of the rheology of ilmenite and ilmenite-bearing aggregates, characterization of the thermal history of the upper mantle and the geological processes that affect it, and trace element geochemical investigations into lunar cumulate mantle overturn, melt migration in the mantle, and other dynamic processes in planetary interiors To learn more about Nick's research, visit his personal research site.
Rachel Bernard, Ph.D., expected 2018
My research, under the guidance of Dr. Whitney Behr, focuses on the present-day rheology of the lithospheric mantle beneath the Mojave region and the controls on lattice preferred orientation in natural deformed mantle rocks. I am also very active in outreach and science communication as a student in the [link:http://museumstudies.finearts.utexas.edu/]UT Museum Studies Graduate Portfolio Program[/link], and as a participant in the [link:http://www.esi.utexas.edu/outreach/scientist-in-residence-program/]UT Scientist-in-Residence Program[/link].
Peter O Gold, Ph.D., expected 2017 (Supervisor)
Owen A Callahan, Ph.D., expected 2017
I am interested in fluid flow in faults and fractures, specifically the interplay between chemical alteration, mechanical deformation, and conduit evolution in hydrothermal systems.

I am a structural field geologist with a particular interest in large-scale tectonics. My research uses geo- and thermochronology to understand the thermal structure and temporal evolution of rifting at magma-poor margins to answer an unresolved question in plate tectonics -- How do you break a continent?
Carolyn Tewksbury Christle (Supervisor)
Alissa J Kotowski
I'm pursuing my Ph.D. at the Jackson School of Geosciences, working with Whitney Behr and Danny Stockli. I graduated from Boston College in 2014, where my undergraduate research background focused on Earthquake Migration along the North Anatolian and Alpine Faults with links to regional tectonics and structure. My broad interests encompass tectonic processes, structural geology and metamorphic petrology. My research at UT focuses on the structural and rheological evolution of high-pressure metamorphic rocks during subduction and exhumation from Syros, Greece. More broadly, I'm interested in large-scale geodynamic processes, and the links between rock rheology and seismic processes in subduction zones.
My research interests include paleopiezometry, rock mechanics and strain localization in the lithospheric mantle. I am examining stress-grainsize relationships in feldspar and orthopyroxene in naturally deformed rocks, in an effort to test experimental extrapolations of these relationships to estimating stress in the lithosphere. I am also exploring the mechanisms and longevity of strain localization in the lithospheric mantle through experimental deformation of dry olivine aggregates.
