Dr. D. Shashidhar has an M.Sc. (Tech.) with a 1st Rank in the University in 2003 and a Ph.D. degree both in Geophysics from the Osmania University, Hyderabad. Presently, he is a Scientist at CSIR-NGRI. He specializes in seismology and his research areas include Waveform modelling for source mechanism of earthquakes and crustal structure; Borehole seismological studies; Application of different techniques for source characteristics; Stress inversion studies using fault slip data; and Estimation of 3D-seismic velocities using earthquake data by applying tomography inversion approach. One of his significant results include estimation of precise focal depths of earthquakes thorough waveform modeling approach that provided crucial inputs in planning of the proposed deep drilling program for target earthquakes. Dr. Shashidhar has wide experience in installation of seismological networks and real time monitoring of seismicity. He has vital participation in setting up of a unique borehole seismic network, the first of its kind, at Koyna, India. He has published over 30 research papers in national and international journals and presented papers in various conferences. Dr. Shashidhar is elected as an Associate Fellow of the Telangana Academy of Sciences.
