Image result for Bela Bollobas

Professor Béla Bollobás FRS is the Jabie Hardin Chair of Excellence in Combinatorics at the University of Memphis, and a Fellow at Trinity College, Cambridge. Professor Bollobás is one of the world's leading mathematicians in combinatorics. He has a huge published output, which includes major contributions to many different branches of this very large area, such as random graphs, percolation, extremal graphs and set systems, isoperimetric inequalities. His main area of research is combinatorics, particularly in graph theory. The two areas that interest him most are extremal graph theory and random graph theory.
