Professor Platt's research interests center on the mechanics of crustal deformation, particularly on convergent plate boundaries and in collisional orogens. His research tools include field-based structural geology, integrated with the mechanical analysis of large-scale dynamic systems such as thrust belts and collisional plateaux. This is supported by microstructural analysis to elucidate deformation mechanisms, rheology, and crustal strength; thermobarometry and geochronology; and paleomagnetism to determine rotational history.
His recent publications (2017-2020) demonstrate a continued focus on shear zone mechanics, subduction zone processes, and the tectonic evolution of key regions including the Franciscan Complex of California, the Alborán Domain in the western Mediterranean, and the Betic-Rif arc system. His work integrates field observations with mechanical modeling to understand crustal deformation across multiple scales.

Professor Platt has secured substantial research funding from the National Science Foundation, United States Geological Survey, and the Southern California Earthquake Center. His funded projects include studies on the deep structure of lithospheric fault zones, geological constraints on subduction zone interfaces, and collaborative research through the PICASSO program investigating the Alboran Sea system. His research has involved collaborations with scientists from multiple disciplines including petrology, geochronology, and geodynamics.
Professor Platt is affiliated with the Southern California Earthquake Center, where he contributes to research on fault systems and seismic hazards in Southern California. His work often involves collaborative field studies and integrates multiple analytical techniques to understand complex tectonic systems.
