** 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.
