Principal Investigator

Stephen Fleming [cv]

Steve Fleming is a Principal Research Associate at the Wellcome Trust Centre for Neuroimaging, University College London where he leads the Metacognition Group. The group’s research focuses on the mechanisms supporting conscious awareness, metacognition and decision-making in the adult human brain.

Steve received a first class BA in Psychology and Physiology at Oxford University (2003-2006) before completing a PhD in Cognitive Neuroscience at UCL under the supervision of Ray Dolan and Chris Frith, investigating awareness in perceptual decision-making (2006-2011). He was awarded a Sir Henry Wellcome Postdoctoral Fellowship to study with Nathaniel Daw at New York University and Matthew Rushworth at Oxford (2011-2015), building computational models of self-monitoring. In 2006 he received the British Psychological Society Undergraduate Award and the Gibbs Prize in Psychology, Physiology and Philosophy from the University of Oxford. Since then Steve's research has been recognised with the William James Prize from the Association for the Scientific Study of Consciousness (2012), a "Rising Star" designation by the Association of Psychological Science (2015) and the Wiley Prize in Psychology from the British Academy (2016).

Steve is actively involved in public engagement and has given public talks about neuroscience and consciousness both in the UK and the USA. He is Executive Director of the Association for the Scientific Study of Consciousness. He has written general-interest articles for outlets including Aeon, Scientific American and Psychology Today, and the lab’s work is regularly featured in the mainstream media. 

Postdoctoral Research Associates

Dan Bang [web]
d.bang [at]

As a slight academic detour, Dr. Dan Bang spent his early days in Beijing studying Mandarin Chinese. Following that he read for a BA in Linguistics at Aarhus University before becoming involved with the Interacting Minds Centre at Aarhus University; working as a Research Assistant for Bahador Bahrami, Andreas Roepstorff and Chris Frith. Dan then read for a Masters degree in Cognitive & Evolutionary Anthropology under the supervision of Robin Dunbar at the University of Oxford. Upon completion of his Masters, he read for a DPhil degree under the supervision of Jennifer Lau and Chris Summerfield at the Department of Experimental Psychology, University of Oxford. His DPhil research broadly concerned how people compute and integrate confidence during group decision-making. As a postdoc in the Metacognition Lab, Dan is working on dissociating the different types of uncertainty that affect our sense of confidence.



Marion Rouault [web]

Dr. Marion Rouault completed her PhD work with Etienne Koechlin investigating executive control and decision-making in prefrontal cortex. This work focused on two types of value signals in choice outcomes, belief and reward values, which concurrently control decisions. She is interested in the neurocognitive mechanisms underlying metacognition, learning and decision-making in humans. As a postdoc in the Metacognition Group Marion is investigating how the sense of confidence changes in the presence and absence of feedback, and its relationship with metacognition, at the behavioural, computational and neural levels. She is currently investigating how a sense of confidence is built and maintained and the functional role of these signals in guiding learning and decision-making. In addition, she aims to understand how a global sense of confidence such as individual self-esteem is built from local, task-dependent confidence. Possible extensions of this work include the study of metacognitive impairments in certain psychiatric disorders characterized by changes in self-evaluation.

PhD Students


Max Rollwage
max.rollwage.16 [at]

Max graduated with a Diploma in Psychology from Philipps-University Marburg. In parallel, he was working as research assistant at the German Primate Center and European Neuroscience Institute in Göttingen, for Igor Kagan, Arezoo Pooresmaeili and Melanie Wilke. Generally, he is interested in the process of decision making, individual choice-differences and especially in the metacognitive evaluation of previous decisions. Max is carrying out a PhD in the MetaLab funded by the Max Planck-UCL Computational Psychiatry Centre, and supervised by Steve Fleming and Ray Dolan. He plans to investigate the link between metacognition, confidence and political beliefs.

Research Assistants


Jason Carpenter (co-supervised with Hakwan Lau)
jcarpenter542 [at]

Jason graduated from UCLA with a Bachelors degree in Cognitive Science. He joined the Metacognition Group in November 2015 after working with the lab from abroad at UCLA with lab collaborator Hakwan Lau. He studies the neural correlates of consciousness and metacognition by implementing a combination of psychophysics, fMRI, and computational modelling techniques. Jason is currently involved in two projects: 1) investigating whether metacognitive ability can be trained in the human brain and 2) examining how prior expectations alter metacognitive accuracy.

Masters students


Shaima Alsuwaidi
shaima.alsuwaidi.16 [at]

Shaima studied for a Bachelors in Chemical Engineering before joining the MSc in Neuroscience programme at UCL. She is working with Marion on a project using fMRI to examine domain-general computations supporting changes of mind.

Steven Chau
steven.chau.16 [at]

Steven completed his medical training in psychiatry in Hong Kong before joining the MSc in Neuroscience programme at UCL. He is working on developing connectivity-based imaging analyses to further understand the role of subregions of the frontopolar cortex in metacognition.


Oriane Armand graduated with a Bachelors in Biology and completed a Masters in neuroscience in Paris before coming to UCL to study for the MSc in Advanced Neuroimaging. She conducted a study in the MetaLab investigating the relationship between motor force and metacognition with psychophysics. Oriane is now a Research Assistant at the Institute of Philosophy, London.


Tricia Seow graduated from the MSci in Neuroscience at UCL before working as a Research Assistant in the lab. Her projects included exploring the influence of social context on visual consciousness as well as building large-scale web-based studies that aim to relate features of metacognition to individual differences in personality and psychiatric symptoms. Tricia is now a PhD student with Claire Gillan at Trinity College Dublin.
