Prof. Santanu K. Bhowmik

IIT Kharagpur, India

Prof. Bhowmik is a metamorphic petrologist with vast experience in applying diffusion chronometry to constrain the timescales of geological processes. His research includes field geology, petrology, and kinetic modeling to unravel the thermal evolution of the Earth’s crust. He is an elected Fellow of the Indian Academy of Sciences (IASc) and the Indian National Science Academy (INSA).

Dr. Ralf Dohmen

Ruhr Universität Bochum, Germany

Dr. Dohmen is a senior research scientist specializing in reaction kinetics and diffusion processes in multi-phase systems. His work focuses on quantifying diffusion coefficients in minerals and developing innovative approaches using silicate thin films for volume and grain-boundary diffusion experiments. He brings extensive expertise in experimental methodologies in mineral kinetics to the workshop. Dr. Dohmen currently serves on the editorial board of Contributions to Mineralogy and Petrology (Springer).

Dr. Surya Snata Rout

National Institute of Science, Education and Research, India

Dr. Rout is a planetary scientist whose research focuses on understanding the formation and evolution of extraterrestrial materials through advanced micro- and nano-analytical techniques, including electron microscopy, Raman spectroscopy, SIMS, and atom probe tomography. His work addresses the isotopic and chemical evolution of the solar protoplanetary disc, the origin and evolution of meteorite parent bodies, space weathering on airless bodies such as asteroids, Mercury, and the Moon, and the shock and impact history recorded in meteorites. He also investigates the flux of extraterrestrial materials to Earth and develops correlative analytical methods to integrate complementary datasets from the same sample.

Dr. Priyadarshi Chowdhury

National Institute of Science, Education and Research, India

Dr. Chowdhury is an Earth scientist whose research integrates field studies, metamorphic petrology, geochemistry, and geodynamic modelling to unravel the evolution of the continental crust and lithospheric dynamics on the early Earth. His work connects mineral-scale diffusion chronometry with large-scale geodynamic processes to bridge the gap between micro-scale records and crust–mantle evolution. He is a recipient of the 2025 MSA Award from the Mineralogical Society of America, a Life Fellow of the Mineralogical Society of America, and an Associate of the Indian Academy of Sciences.
