Richard Arratia, Ph.D. 3620 S. Vermont Ave, KAP 108, Los Angeles, CA 90089-2532 +1(213)740-3774 rarratia@math.usc.edu http://almaak.usc.edu/~rarratia/
Research Interests: Professor Arratia studies probability, combinatorics and number theory, especially the relation between dependence and independence. He has written a book about logarithmic combinatorial structures, and papers about coalescing and annihilating random walks and brownian motions, symmetric exclusion processes, sequence matching, Poisson approximation, the interlace polynomial for graphs. A favorite topic is the similarity between factorizations of random integers on the one hand, and the cycle structure of random permutations on the other hand. He serves, jointly with Sergey Lotosky, as faculty advisor to Pi Mu Epsilon, the undergraduate math honors society.
