Luc's research focuses on large scale, tectonic questions, specifically the dynamic structural and geodynamical evolution of continental and oceanic rifts as well as collisional environments. To address these questions, he has used and developed numerical techniques to model tectonic processes on crustal and lithospheric scales. Luc uses a variety of geophysical and geological data to constrain and quantify tectonic processes. These different studies led to the development of parametrizations to understand such phenomena as the localization of deformation and the initiation of subduction.

Areas of Expertise

Tectonics; the structural and geodynamical evolution of continental and oceanic rifts, as well as collisional environments; numerical techniques to model tectonic processes on crustal and lithospheric scales; deformation; subduction


Graduate Students

Dominik A Kardell , Ph.D., expected 2020 (Committee Member)
I am interested in the evolution of oceanic crust and the processes that affect its physical properties. I am currently performing extensive seismic velocity analysis using MCS data from the Crustal Reflectivity Experiment Southern Transect (CREST). My goal for this project is to characterize the velocity structure of the upper oceanic crust in the western South Atlantic, which has implications for the effect of magmatism and hydrothermal processes on the makeup and geologic structure at slow to intermediate-spreading crust.

Gabriel Travassos Tagliaro , Ph.D., expected 2019 (Co-supervisor)
Gabriel received a B.S degree in Geology from Unisinos University in Brazil, and is currently a Ph.D Student at University of Texas. He is interested in the evolution of continental margins. Gabriel uses seismic data, well data, and numerical modeling to better understand the mechanisms that control sedimentation and deposition in continental margin sedimentary basins, and the interactions between sea-level changes and tectonic processes. Research focuses on Neogene interval of the Northwestern Australian Margin.

Xinyue Tong , Ph.D., expected 2018 (Supervisor)
I use develop numerical experiments of subduction to investigate how slip and long-term deformation accumulate and interact at subduction zones during earthquake cycle. Including, 1. Explore the relationships between long-term strain accumulation and the seismic cycle. 2. Explore mechanisms that could explain how strain accumulation is modified in space and time by the presence of large asperities at the subduction interface.

Baiyuan Gao , Ph.D., expected 2018 (Committee Member)
Baiyuan is currently applying geomechanical models to study thin-skinned fold and thrust belts system. The research will further our understanding of stress, strain and compaction behaviors in fold-and-thrust belts. Baiyuan also aims to comp up with an improved approach to predict pore pressure in compressional regions.

Emily Cooperdock , Ph.D., expected 2017 (Committee Member)
Research Interests: Method development for (U-Th)/He analysis; Fe-oxide (U-Th)/He dating; X-Ray Computed Tomography application to geologic samples; timing of serpentinization in tectonic processes; trace element cycling during serpentinization; magnetite formation; U and Th partitioning during metamorphism

Joshua K Davis , Ph.D., expected 2017 (Supervisor)
My research focuses on deciphering the break-up history of East India and East Antarctica. The project involves developing a holistic plate model for the breakup of East Gondwana (Antarctica, Australia, India, Madagascar, Seychelles, and Sri Lanka) and the subsequent seafloor spreading in the Mesozoic Indian Ocean. Then, coupling recent geophysical data from the margins with our plate model, I can develop a conceptualized tectonic model for the breakup of India and Antarctica. Via 3D numerical modeling we will test the plausibility of our tectonic model. Ultimately this work will seek to investigate the controls on margin development and segmentation during rifting and provide insight into the role that volcanism plays in the subsequent margin morphology.

Landon Lockhart , M.S., expected 2017 (Committee Member)
Landon's research is focused on characterizing the pressures and stresses in complex geologic settings. Specifically, his research integrates geomechanical modeling, experimental analysis, and field data at the Mad Dog Field, deepwater Gulf of Mexico. The title of Landon's thesis is "New Pore Pressure Prediction Workflow to Capture the Effects of Mean Effective Stress and Deviatoric (shear) stress at the Mad Dog Field." Landon has also recently developed a new online software tool (UT-FAST-P^3) to predict pore pressure based on mean- and shear-stress. The software is expected to be available on the UT GeoFluids website by November 2017.

Guangliang Wu (Supervisor)
My doctoral research was focused on tectonics, geodynamics, and structural geology. My dissertation is titled [italic]Continental extension in orogenic belts: Modes of extension, origin of core complexes, and two-phase postorogenic extension[/italic]. I defended my dissertation on Apr. 15, 2016, and graduated on May 21, 2016 with a Ph.D. degree in [italic]Geological Sciences[/italic]. Starting Sep. 19, 2016, I will be a research fellow at the University of Melbourne, Australia. I will work on dynamic processes in continental collision zones, coupling numerical modeling with synthesis of geological observations.

Nikki M Seymour (Committee Member)
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?
