My work focuses on systems where ionic transport, hydrodynamics, and soft-matter organization are deeply intertwined. One major direction concerns electrohydrodynamic ion transport at the nanoscale, where reduced friction and strong confinement give rise to fast, highly correlated ionic flows. I am particularly interested in how active ionic fluxes can couple to electrostatics and hydrodynamics to produce symmetry breaking, autonomous currents, and other emergent behaviors with potential relevance for neuromorphic and iontronic technologies.

In parallel, I investigate oscillatory active media and non-reciprocal soft matter, focusing on how interactions, internal cycles, and symmetry constraints shape collective dynamics. Recent work on self-oscillating colloids has shown how hydrodynamic interactions can generate coupled orientational and temporal order, leading to mixed phase–alignment states and new forms of collective organization.

Together, these efforts aim to build a multiscale understanding of how ionic, mechanical, and hydrodynamic processes can be harnessed to design adaptive, energy-efficient soft materials and functional systems.
