Ieke Moerdijk is a professor of mathematics at the Mathematisch Instituut of the Radboud University Nijmegen. Previously he was in Utrecht. His main interests are in sheaf and topos theory, descent and cohomology, synthetic differential geometry, operads, groupoids, stacks and orbifolds, Lie groupoids and foliations, and abstract homotopy theory (Quillen model categories).
