Dr. Durbha. S. Ramesh graduated in applied geophysics from the University of Roorkee (now Indian Institute of Technology, Roorkee) during 1984 and joined the National Geophysical Research Institute (NGRI), Hyderabad as a research scholar. In the year 1985 he co-founded the seismic tomography group at the NGRI. Ramesh obtained his Ph.D. in seismology during 1991 applying the techniques of seismic tomography and anisotropy to constrain models of evolution of the Deccan Volcanic Province (DVP). His seismic anisotropy results for the Indian shield helped the scientific community to recognise the importance of plate motion related strain in forging anisotropy in the cratonic regions as opposed to the then popular fossil strain hypothesis. In recognition of these enduring contributions by Ramesh, several prestigious National awards such as the Indian National Science Academy (INSA) Young Scientist Medal and Associateship of the Indian Academy of Sciences came to him. During 1992-1993, Ramesh visited Ruhr University, Bochum, Germany on the coveted Commission of European Communities Fellowship to carry out Post-Doctoral work to image the mantle transition zone beneath the Eastern Europe utilising modern digital Broadband Array seismology data. This enabled him lay the foundations for advent and use of Broadband seismological data in solid earth problems related to the Indian shield encompassing both source and structure processes of the Indian lithosphere. The Alexander von Humboldt Foundation (AvH), Bonn, Germany in recognition of the original scientific contributions of Ramesh, has selected him for award of the prestigious Humboldt Fellowship in 1997. Ramesh visited the famous GeoForschungsZentrum (GFZ), Potsdam, as a Humboldt Fellow and worked on the nature of correlation and de-correlation of the mantle transition zone 410-km and 660-km discontinuities, a global geophysical frontier problem with far-reaching impact on the nature and composition of the Earth’s interior. During 2000-2001 he revisited the GFZ as a Humboldt scholar and made an extensive publication on the nature of continental crust of Precambrian North America that resulted firming-up compositional unity of shield regions. The Earthquake Research Institute of the University of Tokyo, Tokyo, Japan has invited Ramesh twice between 2003 and 2005 to introduce the receiver function approach to short-period data. Recently, Ramesh co-founded a new group to focus on the evolution of shallow mantle stratigraphy (150-350km depth) and depth origin of mantle plumes through inventive application of principles of information theory. Ramesh who was also an adjunct professor at the Osmania University (2008-2011) is presently working at the N. G. R. I. as a chief scientist.
