** ****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.

Under this link, you will find some notes of various courses on subjects in
algebraic topology taught earlier at Utrecht and in Nijmegen.

** ****Preprints and publications**

Moerdijk's preprints 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links to some unpublished papers, or papers which are otherwise hard to find: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.
- A paper on the six operations of Grothendieck
for etale groupoids.
- Lecture at ECM 2000.
- Bisimplicial sets and the
group-completion theorem.
