Jayanta Kumar Pati
Professor at Earth and Planetary Science – Director at the National Centre for Experimental Mineralogy and Petrology
University of Allahabad
Jayanta Kumar Pati is a trained Experimental Mineralogist and Petrologist and currently teaches Mineralogy and Petrology to post-graduate students in the Department of Earth & Planetary Sciences, University of Allahabad. He is also serving as the Director of National Centre of Experimental Mineralogy and Petrology, University of Allahabad, India. He has worked in natural and synthetic rock systems up to 30 kb using various high P-T static high pressure equipments. He served the Geological Survey of India, Government of India (1992 – 2000) as a Geologist prior to joining the University of Allahabad in 2000. In addition, he has mapped large part of Bundelkhand craton, India and made some spectacular discoveries including the Bundelkhand Tectonic Zone, an Archean age suture zone. Jayanta is the only Indian till date to establish a confirmed meteoritic impact structure (Dhala structure, Shivpuri district, India) based on the petrological study of the impactites in 2005/2008. It is the largest complex impact structure in SE Asia and the seventh oldest as per the Earth Impact Database. He also focuses on local environmental issues along with planetary science research. He is involved in several Govt. of India funded and collaborative research projects with colleagues from India and abroad. In his free time he enjoys painting and gardening.
