Barry Cooper is Professor of Mathematical Logic at the University of Leeds. A graduate of the University of Oxford, his research follows that of Alan Turing in its focus on the nature of mental and physical computation. Author and editor of numerous books, including Computability Theory, New Computational Paradigms, and Computability in Context, he is a leading advocate of multidisciplinary research at the interface between what is known to be computable, and theoretical and practical incomputability. Chair of the Turing Centenary Committee, which coordinated the international Turing Centenary celebrations, he is President of the Association Computability in Europe, which is responsible for the largest computability-themed international conference series, and chairs the Editorial Board of its Springer book series "Theory and Applications of Computability."
