He studied geophysics at the Indian Institute of Technology, Kharagpur and earned a PhD in Geophysics from Kyoto University, Japan. He was engaged in industrial research for nearly a decade before joining Delft University of Technology in 1999. Between 2005 and 2015, he was an Associate Editor of Near Surface Geophysics. His research interests are in high-resolution seismics with a focus on shear waves, near-surface and geotechnical geophysics, physics-based quantitative integration in geophysics, seismic attenuation, poroelasticity and property estimation, seismic wave propagation in fractured media and anisotropy, and monitoring CO2 sequestration.
