I am interested in condensed matter physics. The question of what happens when many degrees of freedom come together fascinates me. I spend most of my time working on systems with many fermions. My most recent fling is with topological phases of many fermions, where I am trying to understand how really “topology” enters the description of many fermions. I also try to keep up with the fashions working on an assortment of problems in cold atoms and strong correlations.
