Professor Alexei Borodin is a Professor of Mathematics at M.I.T. He was a professor at Caltech in 2003-2010. From 2013-2016, he served as co-chair of the Graduate Faculty Committee in pure mathematics. Borodin studies problems on the interface of representation theory and probability that link to combinatorics, random matrix theory, and integrable systems. He has made seminal contributions to the theory of big groups, to determinantal processes and most notably to the elucidation of Macdonald processes, which have important applications to the statistical physics of directed polymers, tiling models and random surfaces. His focus lies in the field of Integrable Probability. He was awarded the Prize of the Moscow Mathematical Society in 2003 and the Prize of the European Mathematical Society in 2008. In 2015, Borodin received both the Loeve Prize and the Henri Poincare Prize. This Poincaré prize is awarded every three years at the International Mathematical Physics Congress, recognizing outstanding contributions in mathematical physics. In 2016 he received a Simons Fellowship by the Simons Foundation.
