Current Research

・Climate changes, Earth system dynamics and biotic evolution/extinction driven by astronomical/internal forcing.・Recovery process from mass extinctions (end-Devonian, Carboniferous, Permian-Triassic, Triassic/Jurassic), glaciation (Carboniferous-Permian, Jurassic-Cretaceous) and Oceanic Anoxic Events (Permian-Triassic, Toarcian, and Cretaceous).・Geochronology (Astrochronology/Cyclostratigraphy of marine-terrestrial sedimentary sequences. Astronomical time scale.)・Chaotic evolution of Solar Planets (Earth-Mars secular resonance, Earth-Moon gravitational interaction)・Dinosaur Evolution linked with Climate changes
