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.


J
asper 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.
