Deepayan Banik

I am an interdisciplinary computational and theoretical physicist working on mathematical modelling of complex physical systems, with emphasis on reduced-order theory, nonlinear PDEs, statistical methods and high-performance computing.

My research spans from astrophysics to engineering: planetary atmospheres, stellar interiors, granular materials, fluid-structure interactions, compliant mechanisms and more, with a focus on model development and evaluation. My primary interest lies in dynamical systems applied to natural and technological applications, with a current goal of using Agentic AI tools to accelerate scientific development from specific to generalized cases.
