Doctoral Program in Earth Evolution Sciences

Earth Evolution Sciences are the scientific study of structure, composition, history and mechanics of our planet by quantitative geological, physical, chemical and biological methods for forecasting the future. The Doctoral Program in Earth Evolution Sciences embraces a wide range of fields, including paleobiological sciences, paleogeosphere science, geodynamics, petrology, mineralogy, planetary resource geology, and condensed matter geoscience; the last is an exchange program with the Geological Survey of Japan. Such broad program allows students to become familiar with world-class research and capable of making substantive contributions. The graduate programs also provide professionals with a high level of theoretical and practical knowledge. Degrees to be awarded in the course are Doctor of Philosophy in Science, or Doctor of Philosophy in Geoscience.

SASHIDA Katsuo Staff Database Professor Paleozoic and Mesozoic radiolarians sashida@geol.tsukuba.ac.jp
My main researches are focused on taxonomy and biostratigraphy of Paleozoic and Mesozoic Radiolaria and biology of recent Radiolaria. Also I have an interest in mass extinction events during the Phanerozoic era, and Paleozoic and Mesozoic paleozoogeography and tectonic development of Southeast Asia.
AGEMATSU Sachiko Staff Database Associate Professor Conodont, graptolite, tentaculite agematsu@geol.tsukuba.ac.jp
My research focuses on conodont taxonomy, biostratigraphy, and geological history of Asian paleocontinents.

 

Paleogeosphere Science http://www.geol.tsukuba.ac.jp/~strati/index.html

HISADA Ken-ichiro Staff Database Professor Sedimentary petrological study of orogenic belts in Asia hisadak@geol.tsukuba.ac.jp
My research topics cover the sedimentology and tectonics of the accretionary complex on land. Also I have a great interest in the provenance study using heavy minerals and clastics. My fieldworks extend from the Japanese Islands to East and South Asia.
Kamata Yoshihito Staff Database Associate Professor Stratigraphy yoshi_kamata@geol.tsukuba.ac.jp
FUJINO Shigehiro Staff Database Assistant Professor Stratigraphy shige-fujino@geol.tsukuba.ac.jp

 

Geodynamics http://www.geol.tsukuba.ac.jp/~press_hp/index.html

ENESCU Bogdan Staff Database Associate Professor Seismology, Tectonophysics benescu@geol.tsukuba.ac.jp
My main scientific interest is to understand the physical processes that control the occurrence of earthquakes and find ways to better assess and mitigate the earthquake risk. I am currently involved in research on various aspects of earthquake and non-volcanic tremor triggering, either due to static and/or dynamic stress changes. I have also a strong interest in studying the seismic properties of the crust and their temporal variations.
UJIE Kohtaro Staff Database Associate Professor Structural geology kujiie@geol.tsukuba.ac.jp
YAGI Yuji Staff Database Associate Professor Seismology, Tectonophysics yagi-y@geol.tsukuba.ac.jp
Seismic source models are important in estimating crustal deformation, strong ground motion, tsunami and aftershock activity as well as for understanding nature of earthquakes. We have been developing method for analysis of stress accumulation and relaxation process during a large earthquake cycle so as to construct proper seismic source model, and applying it to geophysical observation data.
TAKIZAWA Shigeru Staff Database lecturer Structural Geology,faultrock, mylonite takizawa@geol.tsukuba.ac.jp
Structural geology, analytical and expeimental studey of deformatioal rocks such as mylonite and fault rocks

 

Petrology http://www.geol.tsukuba.ac.jp/~gansekihp/index.html

ARAKAWA Yoji Staff Database Professor Petrology and petrochemistry of igneous rocks, Radiometric age determination Isotope geochemistry yaraka@geol.tsukuba.ac.jp
My main researches are focused on petrology, petrochemistry, and geochronology of igneous rocks worldwide. Petrology and petrochemistry (including isotope geochemistry) are necessary for clarifying the origin, genesis and formation process of igneous rocks, and geochronology technique is indispensable for understanding their absolute ages. These research approaches potentially provide keys for deciphering not only the role of igneous process in earthfs interior, but also tectonic process and history of the earth.
TSUNOGAE Toshiaki Staff Database Professor Metamorphic petrology tsunogae@geol.tsukuba.ac.jp
My research interests are mainly on metamorphic petrology, particularly focusing on pressure-temperature-time (P-T-t) evolution of high-grade metamorphic terranes and the role of fluids in the lower crust. They are all field-based studies, but laboratory works such as textural observation of thin sections, electron microprobe analysis of minerals, thermodynamic calculations of mineral phase equilibrium, and microthermometric study of fluid inclusions are also important. My current study field are granulites in South India, East Antarctica, and South Africa, which are all related to subduction and continental collision during the amalgamation stage of supercontinents.
IKEHATA Kei Staff Database Assistant Professor Petrology, Economic Geology, Geochemistry, Volcanology ikkei@geol.tsukuba.ac.jp
My main research interests are distribution and behavior of volatile and metal element in magmatic-hydrothermal system.
