I am a theoretician working on nonequilibrium, soft matter, and (maybe) biological physics. I am especially interested in Active Matter, which aims to draw living systems, with their unique properties, into the condensed matter fold. Any system that carries out sustained conversion of chemical or other energy into movement qualifies, and some of my favourite active matter is non-living. I am also interested in other kinds of strongly driven many-body systems, such as collectively sedimenting particles, and magnets far from equilibrium.
