The fields of study he is best known for: Plate tectonics Paleontology Volcano His main research concerns Lithosphere, Geophysics, Seismology, Gravity anomaly and Continental margin. His biological study spans a wide range of topics, including Geomorphology and Subsidence. His work carried out in the field of Geophysics brings together such families of science as Shear, Simple shear and Thermal. His work deals with themes such as Continental crust, Rift and Plate tectonics, which intersect with Continental margin. Magnetic anomaly and Seafloor spreading are subfields of Paleontology in which his conducts study. His Seafloor spreading research is multidisciplinary, incorporating perspectives in Ridge and Mid-ocean ridge.
