Leonid Bunimovich (born August 1, 1947) is a Soviet and American mathematician, who specializes in dynamical systems. He is known for discovery of a fundamental mechanism of chaos in dynamical systems called the mechanism of defocusing. The most famous class of chaotic dynamical systems of this type, dynamical billiards are focusing chaotic billiards (e.g., the "Bunimovich stadium","Bunimovich flowers", etc.). More recently he introduced so called Bunimovich mushrooms, which are visual examples of billiards with mixed regular and chaotic dynamics. In many physics labs over the world were built experimental devices in the form of various Bunimovich billiards. Bunimovich received his bachelor's degree in 1967 and PhD in 1973 from the University of Moscow. His thesis adviser was Yakov G. Sinai. In 1986 he was awarded Doctor of Sciences degree in "Theoretical and Mathematical Physics". Bunimovich is a Regents' Professor of Mathematics at the Georgia Institute of Technology. He has studied numerous topics in pure and applied dynamical systems, mathematical physics, probability theory and mathematical biology. Notably, Bunimovich introduced and investigated hierarchical models of human populations, traps of internal waves in non-homogeneous stratified fluids, and deterministic walks in random environments. Bunimovich (with Khudyakov and Skums) discovered the phenomenon of local immunodeficiency. He also pioneered rigorous studies of finite time evolution of dynamical systems. Bunimovich has been a Fellow of the Institute of Physics since 1999, and was awarded the Humboldt Prize in Physics in 2002.[1]
