SS Rai earned his BSc degree (Hons) (1973) from Banaras Hindu University (BHU), MTech (1977) from University of Roorkee and PhD (1988) from the Indian School of Mines, Dhanbad. His specializations are in seismology, geo-electromagnetism, and non-linear dynamics. He held various positions as a Senior Scientific Assistant (1978-81), Scientist B (1981-99), Scientist F (1999-2004), Scientist G (2004-08) at National Geophysical Research Institute (NGRI), Hyderabad..
Academic and Research Achievements: Rai's researches are characterized by a purposeful enquiry both in the geological characteristics of the earth's subsurface materials and structure from shallow earth to its upper mantle, as well as design of incisive geophysical experiments to image these. These endeavours, he has pursued from the very beginning with a quantitative fervour, first in the context of geo-electromagnetics that resulted in several enduring research contributions and later, over the past 20 years in seismic tomography progressively refining our knowledge and understanding of India's two most notable terranes, each highly evocative of the earth?s inscrutable processes: in the early Archaean and the ongoing one of Indo-Asian continental collision. Specifically, some of these are (i) development of new and conceptually sophisticated approaches to target mineralized zones, ground water aquifers and kimberlite pipes in south sequence (ii) evidence for a thick high velocity lithospheric keel beneath the Deccan volcanic sequence (iii) elucidation of a classical seismically transparent Archaean crust in the eastern Dharwars.(iv) demarcation of the northern edge of the Indian lithosphere beneath western Tibet, and (v) creation of a regional 3-D velocity image of the entire subcontinent..
Awards and Honours: Rai is a recipient of the MS Krishnan Medal (1991), SS Bhatnagar Prize (1996), CSIR Young Scientist Award (1988), National Mineral Award (2004) and AP Scientist Award (2006). He is Fellow of Indian Academy of Sciences (1996), Bangalore and National Academy of Sciences (India) Allahabad (2005). .
