Academic Activities:

• Earth surface processes as a function of orogenic/epirogenic driven surface uplift and erosional (fluvial) coupling to attain a steady-state landscape in Himalaya, Indo-Burmese range, Shillong plateau and Indian Peninsula. The coupling process in transient landscape show scaling behaviour, which varies from landslide-scale to seismogenic brittle-ductile thrust wedge to the isostatic crustal (Moho) perturbation in Himalaya, which is an important focus of research.

• Deformation partitioning, active deformation and evolution of transient geomorphic signature in the Himalayan front to understand their paleoseismic and neotectonics behavior.

• Coseismic liquefaction and paleoseismic record in the Brahmaputra alluvium and seismically active Himalayan Front.

• Crustal structures and tectonic evolution of Himalaya and Peninsular belt using integrated geological and geophysical data modeling.

• Characterization of SAR Interferometry-based ground deformation from groundwater overexploitation, coseismic deformation, and landslide phenomenon.

Applied Research:

• Comprehensive geotechnical site-characterization using multiparametric Remote Sensing, Geological and Geophysical tools for shallow subsurface imaging including Ground Penetration Radar (GPR) and others.

• Remote Sensing and GIS based Hydrological characterization.

• Tsunami modelling and risk assessment of coastal region.

Transient landscape modeling of Himalaya. The Mio-Pliocene drainage reorganization during Namcha-Barwa syntaxial evolution.

Active structures with variable structures and geomorphic expresions in Nahan Salient of the NW Sub Himalaya. The subdued deformation in the HFT hanging wall with open anticlines and synclines are separated from the highly deformed sequence in the hanging wall of the Out-of-sequence thrust. Also note the high-angle strike-slip fault showing both (d) transpressional and (d’) trans-tensional deformation in different segments.
