Tatsuki Tsujimori

Professor of Geological Sciences

Tohoku University

Tatsuki Tsujimori is a professor of geological sciences at Tohoku University, affiliated with the Center for Northeast Asian Studies and also the Earth Science Department of the Graduate School of Science. His area of expertise lies in petrology, geochemistry and tectonic processes, with a particular focus on metamorphic rocks, such as blueschists, eclogites, jadeitites, and serpentinites.

After earning his Ph.D. (1999) at Kanazawa University and completing post-doc training at Okayama University of Science (2000-2002) and Stanford University (2002–2006), he has held a few academic positions, initially at Okayama University Misasa (2006–2015) and subsequently at Tohoku University (2015–present). Elected as an MSA Fellow in 2013, and a GSA Fellow in 2014, he received the Japan Association of Mineralogical Sciences (JAMS) Award in 2021. . He is currently serving as the Editor-in-Chief of the journal Island Arc and sitting on the editorial boards of eight scientific journals (J. Metamor. Geol., PLOS ONE, Int. Geol. Rev., Island Arc, Geosci. J., Rus. Geol. Geophy., Geol. Acta, GeoGeo, and Geol. Jour.).

Prof. Tsujimori’s research revolves around understanding the geodynamic and geochemical processes of active convergence margins during the Proterozoic and Phanerozoic eras. His investigations span various scales, ranging from mineral equilibrium to plate tectonics. Furthermore, he aims to evaluate hydration and dehydration within subduction interfaces and explore the subsequent interaction between the subducted slab and the mantle. By linking ancient HP-UHP metamorphism in subduction zones to geophysical observations of modern analogs, he challenges the understanding and sheds light on this complex geological phenomenon..
