    Expertise

    Eric Grosfils’ NASA-funded planetary geology research investigates many different types of volcanic features on Earth, Venus and Mars. Most recently he has focused on the mechanics of magma reservoir failure and related processes, i.e. the behavior of volcanic plumbing systems and how they are linked to eruptions and the formation of volcanic features we can see at the surface. This focus is motivated in part by a desire to improve our understanding of volcanic hazards, but as a planetary geologist, he is also seeking to learn more about the complex evolution of different planets in our solar system. His studies, which integrate numerical modeling, GIS, satellite image analysis, and occasionally some fieldwork, are often conducted with undergraduates and/or in close collaboration with colleagues from other institutions.

    As a physical volcanologist, his goal is to improve our understanding of the mechanics of shallow magma storage and migration in order to better understand the conditions associated with some of the largest eruptions (and intrusive events) that occur on Earth and elsewhere in the solar system.

    Research Interests

    • Unraveling the interplay between shallow magma reservoir failure and the formation of volcanoes on Earth, Venus and other solar system bodies.
    • Evaluating the mechanics of ring fault and caldera formation.
    • Construction of a global map of extensional lineaments on Venus in order to gain insight into giant radiating dike swarm formation.
    • Exploring the pedagogy of computational science, a field which integrates computing, mathematics and science in order to explore interesting research-like questions in the classroom.
