Tatsuki Tsujimori is a professor of geological sciences at Tohoku University, affiliated with the Center for Northeast Asian Studies and 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. in 1999 at Kanazawa University and completing post-doctoral training at Okayama University of Science (2000–2002) and Stanford University (2002–2006), he has held several 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 sits on the editorial boards of several scientific journals (J. Metamor. Geol., PEPS, PLOS ONE, Int. Geol. Rev., Island Arc, Geosci. J., Rus. Geol. Geophy., Geol. Acta, GeoGeo, Geol. J., Discover Minerals, CIGG).

Prof. Tsujimori’s research delves into the intricate geodynamic and geochemical processes occurring at active convergence margins during the Proterozoic and Phanerozoic eras. His work encompasses a broad spectrum, from the microscopic intricacies of mineral equilibrium to the grand scale of plate tectonics. By bridging the gap between ancient high-pressure metamorphism in subduction zones and contemporary geophysical observations, Prof. Tsujimori not only challenges conventional understanding but also illuminates the complexities of these geological phenomena.
