Geology and Geophysics
Tectonics
EAPS faculty and students in tectonics study how the Earth has evolved over billions of years, integrating observations from the building and breaking of mountain ranges to the rise and filling of ocean basins, with an eye to their impact on the evolution of life.
Geophysics
Our geophysics faculty and students quantify the forces that currently shape the surface of our planet, from plate tectonics to mountain building, and the strength of the crust and mantle, from cold rocks that break as earthquakes to warm rocks that flow.
Geomorphology
Select EAPS faculty and students focus their research on the study of the origin and evolution of landscapes created by physical and chemical processes including tectonics, the flow of water and ice, and climate change.
Energy
Research in the traditional and unconventional energy thematic areas are conducted by our faculty and students, including the study of the exploration of reservoirs, the sedimentological and structural characterization of wells, and fluid/rock interactions.

Fewer Sensors, Clearer Images: The Future of Seismic Research
05-19-2025
Researchers at Purdue University have theorized a new way to see what lies beneath the Earth's surface. This innovative method, developed by Ph.D. student Sayan Mukherjee and Professor Yunyue Elita Li from the EAPS Department at Purdue University, could greatly enhance industries that require images of the subsurface, all while saving costs and boosting efficiency. Their work has been published in Geophysics.
Lunar meteorite discovery supports Purdue-led model of early Moon evolution

A rock that crash-landed on Earth has made lunar science history, and a Purdue scientist, Tabb Prissel, played a key role in modeling its formation history. For the first time, researchers have classified a whole-rock meteorite as a lunar norite (Arguin 002), an igneous lunar rock type primarily comprised of the minerals orthopyroxene and plagioclase feldspar.

Forbes — The Perseverance rover is currently exploring the rim of the Jezero Crater in an area called Witch Hazel Hill. The rover took some time in April to study a spot where lighter and darker rock outcrops meet. That’s where the unusual rock came into focus. Margaret Deahn, a PhD student in EAPS, is featured in the Forbes article.
NASA finds mysterious skull-shaped feature on Mars — where star-gazers say it doesn’t belong

New York Post — NASA’s Mars rover has spotted something out of this world — a mysterious, skull-shaped elevation – sitting on a slope where star-gazers say it doesn’t belong. The mysterious rock – dubbed “Skull Hill” was discovered April 11 by the Perseverance rover while it was driving down a ridge called Witch Hazel Hill. Margaret Deahn, a Ph.D. student at Purdue University working with NASA was quoted in the article.
