Brian Horton holds a joint appointment with the Department of Geological Sciences (Professor) and the Institute for Geophysics (Research Professor) at UT-Austin.
Brian's research focuses on mountain building processes and sedimentary basin development along convergent plate margins. He utilizes sedimentology, stratigraphy, geochronology, geochemistry, and structural geology to understand modern and ancient orogenesis, plateau construction, sediment provenance, and the evolution of major river networks.

Sarah George, Ph.D., expected 2019
My research focuses on elucidating the timing and mechanisms of shortening, exhumation, and basin evolution in the Eastern Cordillera of northern Peru and Ecuador. By integrating U-Pb geochronology and measured sections from Cenozoic hinterland basins with (U-Th)/He thermochronology and mapping on uplifted Mesozoic and basement units, I hope to provide a detailed chronology of the uplifts that link the Northern and Central Andes.
Lily Jackson, Ph.D., expected 2019
My current research focuses on determining the timing and magnitude of major paleo-elevation changes affecting the northern Andes of Peru and Ecuador. My current methods include provenance analysis such as detrital zircon U-Pb geochronology and siliciclastic petrology, stable isotope geochemistry to infer paleoclimate and paleoelevation, and other traditional methods in sedimentology.
Tomas N Capaldi, Ph.D., expected 2019
I am a second year PhD student, focusing on Cenozoic to modern tectonic evolution of the flat-slab region western Argentina. My research applies U-Pb detrital zircon chronology to modern drainage networks, establishing a baseline to model exhumation histories in the Neogene foreland basin and hinterland evolution. Understanding the Cenozoic record requires clastic sedimentology and stratigraphy, provenance and geochronology, low-temperature thermochronology, and petrography analysis of the foreland basin fill. By applying these various techniques I will better understand the style and timing of upper-crustal deformation associated with ongoing Pampean flat slab subduction.
Amanda Z Calle, Ph.D., expected 2017
My research is focused on the Cenozoic sedimentary, structural and exhumational history of the Eastern Cordillera to modern Chaco foreland basin in southern Bolivia. A multidisciplinary approach of source-to-sink, geochronology, low-temperature thermochronology and structural mapping will be used. Inherited pre-Andean structures and their response to contractional settings will also be evaluated to decipher the Cenozoic evolution of this part of the Central Andes.
Renas I Mohammed, Ph.D., expected 2016
Renas is working on the Zagros fold-thrust belt and foreland basin in Iraq's northern region, Kurdistan. His fields of interest are assessing the effect of sedimentation on deformation sequence and styles, and the controls on wedge dynamics of the northwestern Zagros orogenic belt. He is also interested in understanding the competitive role of axial and transverse drainages in filling sedimentary foreland basins and how sediment dispersal pattern change in response to thrust propagation. In his research, Renas employs field geology (sedimentology/stratigraphy and structure) integrated with a variety of analytical techniques such as: U-Pb geochronology, (U-Th)/He thermochronology, magnetostratigraphy, and petrography. Renas has obtained his MS degree at the University of Texas at Austin in 2011. Currently, he is a PhD student in the same school.
Meredith A Bush, Ph.D., expected 2016
Meredith is a PhD candidate focusing on the evolution of contractional mountain belts and intra-continental basins. Meredith is interested in the tectonics of sedimentary basins in intra-continental settings, clastic sedimentology and provenance analysis. Her current field areas include the Qaidam basin on the Tibetan Plateau, the Raton basin in Colorado and New Mexico, and the Galisteo-El Rito basin of New Mexico. Her research includes a variety of analytical techniques, including magnetostratigraphy, detrital mineral geochronology, heavy mineral analysis and sandstone petrography. Involving students at all levels in project-based learning and field experiences is a priority for Meredith; in addition to a wide range of teaching experience at the University of Texas, Colorado College, and in the Austin public schools, she is taking courses in the UTeach STEM teacher preparation program.
Sebastian G Ramirez, Ph.D., expected 2016
I am currently working on two sub-projects. The first aims at understanding the conditions of Kumano forearc basin (offshore Japan) nucleation and early evolution through 3D-seismic and sandstone petrography provenance analyses. The second involves the study of the Cretaceous-to-Recent sedimentary record in the northernmost Neuquen basin (western Argentina) through traditional field work and detrital zircon analysis. My goal is to better constrain the timing and characteristics of early Andean compression and to test whether or not the observed deformation patterns might be associated with subducting slab shallowing/steepening cycles.
My research focuses on the structural and tectonic evolution of the Argentine Andes. I will be using a combination of structural analysis and thermochronometry to provide modern age constraints for deformation and exhumation events in the Frontal and Pre-Cordillera. Ultimately, this work seeks to relate observed crustal shortening and related age constraints to the structures observed at depth (significantly, at the transition from normal to flat-slab subduction) in order to better characterize the mechanisms that drive Andean uplift and shortening in Mendoza and the surrounding provinces.
