Our research covers every aspect of the geological phenomena from Quaternary deposits to accretionary complexes. Active areas of research include stratigraphy and sedimentology of biosiliceous sedimentary rocks, and micropaleontology (the study of microfossils).
Major research interests include Mesozoic and Cenozoic radiolarian studies; biostratigraphy, speciation and microevolution, paleobiogeography and paleoceanography, and paleoenvironmental change by using phytolith(plant opal).
