PhD thesis submitted, under external review; viva voce forthcoming. Seeking a postdoctoral position.

I study nonequilibrium organization and fluctuations in active interfaces and polymers, with statistical mechanics and large-scale particle simulation.

Membrane height against position on a fluctuating membrane. Orange type-1 particles stack into one tall cluster at a step in the membrane, marked with an arrow and speed v_c; green type-2 particles lie spread along the membrane.
A travelling giant cluster. Two species of active particles on a fluctuating membrane (black, height against position). Type-1 particles (orange) gather into one giant cluster that moves along the membrane with speed vc; type-2 particles (green) stay spread out. From my poster Spatial organisation of multiple species of active particles interacting with an interface (STATPHYS-Kolkata XIII, 2026).

Research

My work is in theoretical and computational soft matter, with a focus on active matter: systems whose constituents convert energy into motion. I combine statistical mechanics with large-scale particle simulation.

Active particles on a fluctuating interface. The particles deform the interface locally while its evolving shape steers their motion. When several species share one interface, some pushing it into valleys and others pulling it into hills, this two-way feedback produces activity-driven spatial organization (Phys. Rev. E 2025).

Active baths and semiflexible polymers. I implemented a discrete-time Ornstein–Uhlenbeck active-noise module for LAMMPS and showed that an active bath is not a uniform heat source: it couples selectively to the modes whose relaxation times match the bath correlation time, which makes the chain a mode-resolved probe of its environment (arXiv 2026).

Earlier work includes Monte Carlo studies of dynamic roughening in the KPZ and Edwards–Wilkinson classes, and a minimal statistical model of membranes with several protein species.
