Tatsuki Tsujimori

Professor of Geological Sciences

Tohoku University


Tatsuki Tsujimori, professor of geological sciences at Tohoku University’s Center for Northeast Asian Studies, earned his Ph.D. at Kanazawa University in 1999. He then completed post-doc fellowships at Okayama University of Science (2000–2002) and Stanford University (2002–2006). From 2006 to 2015 he was a faculty member of Okayama University at Misasa and has been a Tohoku University faculty member since 2015.

Prof. Tsujimori’s research specialties are in the fields of petrology and tectonics processes, with a particular emphasis on HP-UHP metamorphic rocks, such as blueschists, eclogites, and jadeitites. His early research focused on the petrotectonic characterization of the Japanese Paleozoic serpentinite-matrix mélanges enclosing blocks of various HP metamorphic/metasomatic rocks. As a part of this research, he reconstructed the fossilized mantle wedge–slab interface that contained blueschist, jadeitite, and a newly discovered eclogite. Since joining Tohoku University, his research program has focused on better understanding the geodynamic and geochemical processes of Proterozoic and Phanerozoic active convergence margins at different scales from the mineral equilibrium to the plate tectonic levels. Additionally, his work seeks to link the HP-UHP metamorphism of ancient subduction zones to geophysical observations of modern analogs by evaluating hydration and dehydration from within the subduction interface, and the subsequent slab–mantle interactions.

Prof. Tsujimori was the 1st winner of the Sakuyama Award of the Geological Society of Japan in 2006. He was also named a 2013 MSA Fellow and a 2014 GSA Fellow due to his valuable contributions to the metamorphic petrology field, and his ongoing research into lawsonite eclogites and jadeitites has had a significant influence on the geoscience community. Currently, Prof. Tsujimori is the Editor-in-Chief of the journal Island Arc and sits on the editorial boards of several scientific journals (J. Metamor. Geol., PLOS ONE, Int. Geol. Rev., Island Arc, Geosci. J., Rus. Geol. Geophy., Geol. Acta, and GeoGeo).
