My research sits at the intersection of computational fluid dynamics and geophysical hazard engineering. A central challenge in hydraulic engineering is that granular and sediment phases do not behave as passive tracers — they deform, compact, liquefy, and drive flow in ways that single-phase models cannot capture. I develop multi-phase, multi-scale numerical frameworks that treat this coupling rigorously, at a computational cost suitable for engineering practice.

Going forward, I aim to extend these frameworks to three-dimensional settings and to validate them against field-scale events — dam-break failures, debris flows, and flood-induced sediment pulses in Himalayan rivers. India's river systems present some of the world's most challenging and consequential hydraulic engineering problems. I intend to build a research programme that directly addresses disaster resilience in this context, in close collaboration with national agencies.
