He specializes in describing and quantifying temporal and spatial variations in near surface deformation and landscape evolution. To document variability in regional scale deformation he integrates structural, geomorphic, and petrographic data sets. His current research projects involve field work along the Pacific coast of Costa Rica, in central Colorado, and Valley and Ridge of central PA.
