what we do

Those of us in Lehigh University's solid-Earth group work to understand the evolution and dynamics of our planet. Using a blend of field and laboratory-based studies, we aim to understand geological processes operating in the lithosphere and on the earth's surface. We are especially interested in coupled systems linking deep earth and surface processes.  Using approaches in seismology, paleomagnetism, geochemistry, structural geology, geomorphology, and geochronology, our research takes us to field sites across North America and the world.

Our current research includes studies of mountain building and crustal evolution, epeirogenesis and intraplate processes, faulting and deformation, landscape evolution, and mass flux and geochemical cycling in convergent margin systems. To learn more, visit the faculty/staff and collaborative web pages listed on this page.

If you're interested in graduate work at Lehigh, start here for links to the research we do, and then learn more about our graduate curriculum and our admissions procedures. More than anything, we encourage you to contact the person or persons you're interested in working with.
