A short CV
### A short CV of Arjen Doelman

Arjen Doelman was an undergraduate student at the
Mathematical Institute
of the
Leiden University,
he did his master-thesis in 1986 under the
supervision of
Bert Peletier and
Michiel Bertsch. In 1990, he got his PhD
at the
Department of Mathematics
of
Utrecht University. The title of his PhD-thesis
is * `On the Nonlinear Evolution of Patterns - Modulation
Equations and their Solutions *. His PhD project was supervised by
Wiktor Eckhaus.
He worked as a postdoc at the
Center for Applied Mathematics
of
Cornell University with
Philip Holmes
and had a position as assistant professor (`UD')
in the `Applied Analysis' group of the
Department of Mathematics
of
Utrecht University.
He became professor of `Applied Analysis and Dynamical Systems'
at the
Korteweg-de Vries Institute for Mathematics
of the
University of Amsterdam in August 1998. This position was reduced
to a one day a week position in the period September 2004 - January 2009.
In September 2004, Arjen Doelman (partly) moved to a position at the
Center for Mathematics and Computer
Science (CWI), where he was head of the (CWI-)cluster
Modelling, Analysis and Simulation (MAS) in the period January 2007 - December 2009.
In February 2009, he became professor of Applied Analysis
at the
Mathematical Institute
of
Leiden University, in November 2009
he became director of the
Lorentz Center.
After almost 14 years, Arjen Doelman stepped down as director of the Lorentz Center in September 2023. Since then, he has a full-time position at the Mathematical Institute of Leiden University.

His main research interests are in the fields of
nonlinear dynamical systems, pattern formation, singular perturbation
theory and their applications (in oceanography, geophysics, chemistry,
hydrodynamics, ecology, biology, etc.). In 2023, his research on pattern formation in ecology -- and especially on (the evasion of) tipping points in ecosystems -- culminated in the (joint) ERC Synergy project RESILIENCE.
