Abinash is an experimental rock mechanist and petro-physicist specializing in advanced petrophysical characterization of unconventional reservoir rocks, including shale, coal, and tight sandstone. His research integrates laboratory-scale rock deformation and multi-scale porosity–permeability analysis to investigate fluid flow, geomechanical behavior, and reservoir quality.

He focuses on nanopore structure, accessibility, and the evolution of poro-permeability under coupled stress-fluid conditions, with applications in gas transport, CO₂ sequestration, and enhanced recovery in depleted reservoirs. Currently, he is part of the Tri-State Carbon Capture and Storage Project at Ohio State University, in collaboration with WVU, Tenaska, Projeo, and WVGES.

Abinash is one of the key members in establishing the High-Pressure Temperature Triaxial Compression Testing facility at the Experimental Rock Deformation Laboratory of IIT Kanpur, enabling advanced poro-permeability and hydraulic fracturing studies. He is proficient in a range of instruments, including nano pulse decay permeameters, HP-T triaxial systems, Quantachrome Autosorb iQ, He-pycnometers, and various rock preparation tools. He also has experience with synchrotron-based small-angle scattering, micro-CT, SEM, and XRD.
