** ****Ieke Moerdijk**

Izak
(Ieke) Moerdijk studied Mathematics, Philosophy and General Linguistics at the
University of Amsterdam. He received his PhD in
Mathematics from the same institution in 1985, with the distinction Cum Laude.
Subsequently he worked at the University of Chicago and at the University of
Cambridge, before joining the Mathematics Department of Utrecht University in
1988. In 2011, he moved to Radboud University in Nijmegen. In 2016 he moved back
to the University of Utrecht.

Moerdijk was awarded a
Huygens Fellowship from NWO in 1986 and a PIONIER grant, again from NWO, in
1995. He was elected member of the KNAW (Royal Academy of Arts and Sciences) in
2006, and of the Academia Europaea in 2014. In 2011 Moerdijk received the
Descartes-Huygens prize from the Académie des Sciences, and in 2012 the
Spinoza Prize from NWO. He held visiting positions at Cambridge (St John's
College), Montreal (McGill University), Sydney (University) and Aarhus, among others.

Moerdijk's research
interests include algebraic and differential topology, and applications of
topological structures in mathematical logic. He is the coauthor of several
well-known books, including "Sheaves in Geometry and Logic" with S.
Mac Lane (Springer Verlag, 1992, 1994), and "Introduction to Foliations
and Lie Groupoids" with J. Mrcun (Cambridge UP, 2003). Currently, his main
focus is on developing the theory of dendroidal sets.

can be found here, while most of his publications are here.

In addition, here are
links to some unpublished papers, or papers which are otherwise hard to find:

- Cyclic sets as a classifying
topos.
- A paper on the weak homotopy type of etale
groupoids.

Levensberichten (obituaries) 2014 of the Dutch Royal Academy of Arts and
Sciences.
