Berkolaiko, Gregory Professor
Positions
- Professor, Mathematics, College of Arts and Sciences
My research interests focuses on spectral problems in mathematical physics. In particular, graph models, their use in physics in general and in the theory of quantum chaos in particular. I also have interest in combinatorial problems arising in mathematical physics.
