Fluctuating Hydrodynamics

Long-range correlations in non-equilibrium systems

This is my main active topic of research. You can find here presentations I have made on the subject, my most recent publications or preprints of papers I’m currently working on. Most of this work is being done in collaboration with the research group of Professor Jan Sengers, at the University of Maryland, you may found them here
