I have a wide range of interests in the general fields of tectonics and structural geology. I have worked on plate margin evolution, magmatic systems, tectonic evolution of magmatic arcs and mountain belts, fracture-controlled migration of oil and gas, dynamic fragmentation in the earthquake source, and a variety of structural and microstructural problems in deformed rocks. Most recently I have been working on deeply eroded seismogenic shear zones to better understand the earthquake cycle and the rheology of the frictional-to-viscous transition in Earth’s continental crust. Over the next few years I am launching back into familiar territory with a new set of tools – the role of coupled physical and chemical processes (e.g., deformation and metamorphism) in the evolution of continental crust. I enjoy multidisciplinary projects, and have a particular interest in bringing together people from different science and engineering fields to tackle difficult problems in the Earth sciences. I take a holistic approach with my students and their projects. Most of them tend to include elements of field work, laboratory analytical analysis, microstructural analysis, and numerical modeling. Depending on the project, my students and I generally work closely with other UMaine colleagues, including Cici Cruz-UribeChris Gerbi and Peter Koons in the School of Earth and Climate Sciences, and Senthil Vel and Zhihe Jin in the Department of Mechanical Engineering. Our analytical and computational infrastructure allows us to be at the cutting edge of solid-Earth and cryosphere studies. We are always looking for motivated students who want to join our research efforts and enjoy the opportunity to live and study in Maine. If you are a student who is considering working with me or my colleagues, I invite you to email one or more of us to learn about the current opportunities.

  • ERS 103 – Dynamic Earth. A 3-credit introductory course that attracts approximately 250 students per year.
  • ERS 316 – Introduction to Structural Geology. A 4-credit lab course required for ERS majors.
  • ERS 555 – Microstructural Processes. The primary graduate-level course that I teach most every year.
  • ERS 602 – Advanced Topics. I use this avenue to cover a wide range of topics, as needed/requested by graduate and advanced undergraduate students.
