Tatsuki Tsujimori is a professor of geological sciences in the Department of Earth Science, Graduate School of Science, at Tohoku University. He leads the KREATE (KR8) research group, now based on the Aobayama Campus. His research spans petrology, geochemistry, and tectonics, with a particular focus on high-pressure metamorphism and fluid–rock interaction in subduction zones, as recorded in blueschists, eclogites, jadeitites, and serpentinites.

He earned his Ph.D. from Kanazawa University in 1999 and conducted postdoctoral research at Okayama University of Science and Stanford University. He held academic positions at Okayama University in Misasa from December 2006 to September 2015 before joining Tohoku University in September 2015. He was elected an MSA Fellow in 2013 and a GSA Fellow in 2014 and received the JAMS Award in 2021. He serves on the editorial boards of several scientific journals.

Through the mineralogical and geochemical records preserved in metamorphic rocks, Prof. Tsujimori investigates how subduction and fluids have shaped Earth’s evolution. His work spans scales from mineral-scale reactions to plate-scale dynamics, connecting ancient high-pressure metamorphic records with present-day geophysical observations to understand processes operating deep within Earth today.
