Research
I have a broad interest in understanding collective phenomena, transport and pattern formation in non-equilibrium systems. My approach is using theoretical and computational methods pertaining to statistical physics and condensed matter physics.
Topological defects
My main current research is pivoted on understanding some of the macroscopic properties of defected matter through the collective dynamics of its topological defects. Some of the research topics that we address in our group include:
Turbulence and vortex dynamics in superfluid Bose-Einstein condensates
Plasticity and dislocation dynamics in crystalline matter
Hydrodynamics of nematic active matter and its topological defects
Anomalous diffusion
Another research topic is understanding anomalous diffusion in disordered media, reactive media or under confinement. The diffusing entities could be passive Brownian particles moving through a labyrinth or active (self-propelled) Brownian particles moving in a confined space with or without obstacles. The passive Brownian particles could also interact with the environment through trapping sites. Basic open questions in such systems concern the long-time behavior of the mean-square displacement in relation to the topology of the embedding space, dispersion and mixing of particles in porous media, finding the escape probably of (active) Brownian particles in confined spaced, etc.
Interfacial processes
Other projects involve modelling various interfacial processes in multi-phase systems using level-set or phase field methods and geared more toward geophysical applications of fluid-rock interfaces and rock deformation. We aim to develop a theoretical framework for deriving the governing balance laws at the fluid-rock interfaces where dissolution/precipitation reactions are coupled with flow and deformation.
