Principal Investigator

Roshan Cools (CV.pdf) completed her undergraduate degree in
Experimental Psychology, at the University
of Groningen, The
Netherlands, in 1998. She then moved to Trevor Robbins’ lab at the
University of Cambridge, UK, for an M Phil degree (1999), a PhD degree
(2002), a St John’s
College Junior Research Fellowship (2002-2006) and a Royal Society Dorothy
Hodgkin Research Fellowship (2002 – 2006). She spent two post-doc years
at UC Berkeley working with Mark D’Esposito
from 2003, before moving back to Cambridge
in 2005, where she obtained a Royal Society University Research Fellowship
(2006 -2007). In November 2007 she returned to The Netherlands, where she is
now Principal Investigator at the Donders Centre for Cognitive Neuroimaging.
Post docs

Esther Aarts (post-doc) studied medical biology at the Radboud University Nijmegen, The Netherlands. She
graduated in 2004 and then started her PhD project under supervision of
Miranda van Turennout and Ardi
Roelofs at the Donders Institute, studying cue-based adjustments
in cognitive control with fMRI. In 2008, Esther
started working as a post-doc with Roshan Cools on
the role of dopamine in motivational and cognitive control processes in
patient populations (ADHD and Parkinson's disease).

Hanneke den Ouden (post-doc) completed her
undergraduate degree in Life Sciences at University College Utrecht, The
Netherlands, in 2002. She then continued with an MSc
programme in Neuroscience and Cognition at the
University
of
Utrecht
,
part of which she spent completing research projects at the
Institute
of
Cognitive
Neuroscience
in
London
with
Sarah-Jayne Blakemore, and at
Harvard
University
with Marc
Hauser. She moved to
London
for an MPhil (2004) and PhD degree (2005) in the Wellcome Trust PhD programme in
Neuroscience at University College London. She completed her PhD on the role
of prediction errors in associative learning under the supervision of Karl Friston and Klaas Enno Stephan at the Wellcome
Trust Centre for Neuroimaging. In April 2009 she
started a postdoctoral position at the Donders institute, working with Roshan Cools on the role of serotonin in decision-making.

Sean James Fallon started his Ph.D in 2006 under the supervision of Adrian Owen at the Medical Research Council's Cognition and Brain Sciences Unit (MRC-CBU), Cambridge, UK. His thesis examined the dopaminergic basis of deficits in planning and attention in healthy older adults and Parkinson's Disease (PD) patients. In April 2010, he moved to the Donders Institute, Netherlands to start a post-doc with Roshan Cools to examine the extent to which the behavioural response to positive or negative feedback is dependent upon frontal and striatal dopamine levels.
PhD students

Martine van Schouwenburg (PhD student) studied Medical Pharmaceutical Sciences
at the
University
of
Groningen
. In her
current research project she investigates the role of dopamine in cognitive
control.

Marieke van der Schaaf (PhD student) completed an undergraduate degree in clinical neuropsychology at the free university in Amsterdam as well as a Neuroscience and Cognition
Master’s degree at the University
of Utrecht. At the
Donders Institute Marieke focuses on the role of
dopamine in reward- and punishment-based reversal learning.

Dirk Geurts (PhD student, resident in psychiatry) studied medicine and philosophy at the Radboud University Nijmegen. His research focuses on the basic learning(dys)abilities of psychopaths and their neural underpinnings.

Daniel von Rhein (PhD student)
studied cognitive psychology at the Radboud
University Nijmegen, The Netherlands. In his current project he studies the
effects of gene-environment interaction on cognitive brain functions in ADHD
patients.

Jasper Winkel
(PhD student) studied psychobiology and cognitive neuroscience at the
University
of
Amsterdam
. His research project
involves the neuropharmacology and -anatomy of the
trade-off between speed and accuracy in decision making.
Research assistents

Mieke van Holstein (research assistant) completed a Master's degree in Psychonomics at the University of Amsterdam. At the Donders Centre she investigates the effects of methylphenidate on motivational and cognitive control in attention deficit hyperactivity disorder.

Kristin Schmidt studied Psychology and Music (undergraduate), and psychological Research Methods (postgraduate) in Leeds and University College London (UK). She is currently investigating the roles of serotonin in reinforcement learning paradigms of decision making.
Master students
Peter Smittenaar (research master student) completed
a bachelor degree in molecular life sciences (at the University of Nijmegen)
and is currently enrolled in the CNS master's programme
of the Donders. Peter examines the role of dopamine in reinforcement-based
learning and performance in Parkinson’s disease.

Bram Nusselein (research master student) completed a medical psychology master degree at Tilburg University. He is currently enrolled in the cognitive neuroscience research master of the Donders Institute. Bram studies motivational compensation of cognitive decline in Parkinson's disease.
Alumni

Joris Elshout (research assistant) completed a Neuroscience and Cognition master degree at
the
University
of
Utrecht
. At the
Donders Institute Joris studied the role of
serotonin in decision making. |
