I am a postdoctoral fellow in the condensed matter theory group at Harvard University. My main interests are in strongly correlated systems, with a focus on ultracold atoms. Ultracold atoms offer a fresh perspective on strongly interacting many-body systems. In particular, they allow one to simulate and probe models relevant for condensed matter systems, as well as novel models that do not correspond to any natural or man-made materials. Furthermore, ultracold atoms offer the advantage of precise control over model parameters, including tuning them in time, as well as the ability to probe dynamics. At Harvard, I am involved in several projects that focus on both dynamics of cold atoms as well as novel probes of their properties.
