Our research includes a strong focus on fundamental questions about the new physics underlying the Standard Models of particle physics, cosmology, and gravity; and the nature and applications of our basic frameworks (quantum field theory and string theory) for attacking these questions. Our research also includes a major emphasis on the novel phenomena in condensed matter physics that emerge in systems with many degrees of freedom.

The history of particle accelerators is one of seemingly constant one-upmanship. Ever since the 1920s, the machines – which spur charged particles to near light speeds before crashing them together – have grown ever larger, more complex and more powerful.

String theory has enjoyed tremendously fruitful interactions with modern mathematics. Some of the simplest and most interesting questions in number theory and geometry involve counting (for instance, determining numbers of integer solutions to certain equations).
