Academic Record:

  • M. Sc (Applied Physics), Gandhigram Rural University, Gandhigram (1992)


  • Japan Society for Promotion of Science (JSPS) Ronpaku Fellow (2005-2009)
  • Member, 23rd Indian Antarctic Scientific Expedition (2004)

Research Interests:

  • To understand the convergence between India and Eurasia plates and to assess future seismic risk in the western Himalaya
  • Study of inter-seismic, co-seismic and post-seismic crustal deformation using satellite geodesy (GPS).
  • Measurement and modeling of geodynamical phenomena, such as strain rate distribution, litho-tectono-dynamics and rheology of the earthquake prone regions of India and Antarctica.
