Research 

I have a broad interest in collective phenomena, transport and pattern formation in non-equilibrium and complex systems. I use theoretical and computational methods pertaining to statistical physics and condensed matter physics.

 

Topological defects

My main research is pivoted on understanding the dynamics of interacting topological defects in broken-symmetry (ordered) states of matter, and their collective effects on the large-scale properties of matter. In particular, the research topics that we currently study are: 

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 particles 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 involved modelling various interfacial processes in multi-phase systems using level-set or phase field methods and geared mainly toward geophysical applications of fluid-rock interfaces. The idea here is 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.
