Norihiro Yamada: I am a member of the Centre for Mathematics of the University of Coimbra, in which I belong to the Research Group on Algebra, Logic and Topology and the Doctoral Programme in Mathematics (held jointly with the University of Porto). I live in the beautiful city of Coimbra, which has a strong academic tradition, an international environment, rich history and culture. My interests are in pure mathematics and foundational aspects of theoretical computer science: games and geometry in logic and algebra; category theory; constructive mathematics; higher-order logic and computation; operator theory.
