**Education:**

- Ph.D., University of California Davis, The Low Spectrum of the XXZ Model

I received my Bachelor's degree in mathematics at UC Berkeley and my Ph.D. from UC Davis. I held temporary teaching/research positions at Princeton, McGill in Montreal (Canada), and UCLA, and had a permanent faculty position at University of Rochester in upstate New York before finally settling down at UAB.

I have taught courses with a variety of instructional methods, including regularly teaching a two-semester course using inquiry based learning (IBL). In IBL courses in mathematics, students present all the material, especially proofs of theorems, and the instructor spends all their time as an audience member. I also frequently teach and use Mathlab as an element in courses such as Mathematical Statistics, Mathematical Finance, and Advanced Probability. In such classes, computing is one of several useful tools for gaining mathematical understanding and insight.

### Research Interests

Mathematical physics is the study of physical systems using the methods of mathematics, especially rigorous proofs. It is the only fool-proof way to resolve discrepancies or controversies among physicists. A notable example is Peierls's proof in the mid 20th century that phase transitions can occur in physical systems using the set up of theoretical statistical mechanics. This fact was previously doubted by about half the physicists at a major conference. This is the high ideal mathematical physicists aspire to. Probability theory is a necessary part of mathematical physics, just as it is a component of quantum mechanics. I work on mathematics related to quantum spin systems as well as on spin glasses and other topics in probability theory such as random matrices and random permutations.
