I am interested in solving the unresolved tectonic mysteries of earth using the tools in seismology. For this purpose, we deploy seismographs in the regions of interest to collect earthquake data for several years. These seismological data are processed using new as well as conventional modelling and inversion techniques based on statistical tools. More recently, our research group is focused on finding optimal seismic models via modelling complementary datasets extracted from the various time windows of seismograms. We are applying these techniques to the region of north-eastern India and Chhotanagpur Plateau.
Also, we are a dedicated research group to perform seismic microzonation studies to estimate earthquake hazard parameters at a site of interest. We collect/use continuous waveform data to characterize the surficial soil layers up to the depth of basement rock to estimate risk posed by primary and secondary effects of earthquakes.

In my research I analyze seismic waves to image Earth structure and, hopefully, to better understand the processes by which the Earth has evolved to its current state. One common approach is to install a set of sensitive seismic instruments to target certain features and leave them in place to record earthquakes and other events for several years. The data we record can be analyzed to, for example, study characteristics of earthquakes or to produce three-dimensional models of the Earth’s interior.
My research group has recently made deployments, with colleagues, in west Texas and southeastern New Mexico, the Texas/Gulf of Mexico coastal plain, South Texas—broadly to study the processes additional terranes accreted to and modified Laurentia (North America’s old core) and the Dominican Republic, to study the complex plate boundary interactions that occur there.
In addition to the above, current projects include the development of an autonomous seismic array for automated processing of ambient noise data, for exploration and monitoring applications, and the development of joint modeling techniques for disparate types of geophysical data.
