Professor Davis' two main areas of research interest involve the use of analog modeling to study the mechanics of large-scale crustal deformation and application of field geophysical methods to the study of Quaternary geology. Recent work in tectonics has focused on topics including strain partitioning at obliquely convergent plate margins and the mechanics of thin-skinned mountain belts and accretionary wedges. Research interests in field geophysics involves the use of ground penetrating radar and resistivity to study glaciotectonic folding and recent dune formation on Long Island.

Mechanics of Thin-skinned Tectonics 
Davis uses analog scale modeling to study how the mechanical properties of mountain belts affect their fundamental attributes, including size, shape, and the rate, style, and distribution of strain. His work focuses on understanding the roles of such factors as the thicknesses and lithologies of the regional stratigraphic column, the presence of basement structure, and the distribution of excess pore fluid pressures. Davis is studying the seismicity and tectonics of the mountain belts of Pakistan to understand better processes such as oblique plate convergence and the influence of thick continental margin sedimentary sequences on the mechanics of overthrusting. A large analog modeling apparatus is used to study processes associated with oblique convergence. Using automated quantitative analysis of digital images of experiments, Davis and his students have been studying strains associated with convergence in models of varying obliquities and with different rheologies and boundary conditions.

Field Geophysics and Quaternary Geology 
Davis and and his students have been applying field geophysical techniques to the study of young geological features on Long Island. Through a combination of ground-penetrating radar surveys and traditional field geology, they have been characterizing the internal structure of the push moraines of Long Island, which contain folds and thrusts that are in many ways analogous to structures in tectonic foldbelts. These contractional features are often immediately adjacent to glaciofluvial features such as subglacial tunnel valleys. Other glacial features under study include kettle holes, some of which hold proglacial loess deposits that can be mapped out using a combination of GPR and resistivity surveys. They are also using GPR and subsurface sampling to study the internal structure of active parabolic dunes that are advancing across a forest. These features provide a useful analog for Pleistocene parabolic dunes that they have also studied using the same techniques.
