In my research group, we use a combination of analytical theory and computation to study soft and living matter. In living matter, we are interested in how new and general collective phenomena, often beyond those typically observed in inanimate soft matter, can emerge at the subcellular, cellular and tissue levels. In soft matter, we are interested in the glass problem, in the learning problem, and in using data science methods to understand the microscopic origins of collective many-body behavior in strongly correlated systems. My collaborators and I worked for several years on the problem of jamming, where we showed that jamming produces solids at an opposite pole from perfect crystals, providing a new way of thinking about the nature of rigidity in disordered solids. The nonequilibrium jamming transition and jammed state thus serve as useful starting points for understanding a broad class of materials.
