Manuel Arnold’s main area of interest is statistical modelling of human behaviour and ageing. Particularly, he is interested in robustness checks and model evaluation. In his dissertation supervised by Andreas Brandmaier and Manuel Voelkle, he focuses on methods to identify heterogeneity and to estimate individual- or subgroup-specific differences in structural equation model parameters. His project aims at contributing to a shift towards an individualspecific understanding of psychological processes rather than an understanding derived from average-trend models. Manuel received a Bachelor’s degree in Psychology from the University of Hildesheim, a Master’s degree in Psychology from Freie Universität Berlin, and graduated with a Master’s degree in Statistics from Freie Universität, Charité, Technische Universität Berlin, and Humboldt-Universität zu Berlin. Before joining IMPRS COMP2PSYCH, he worked as a research assistant supervised by Manuel Voelkle at the chair of psychological research methods. He is also responsible for the coordination of the Methodological Consulting Unit at the Department of Psychology at Humboldt-Universität.

Rachel Bedder is a second-year PhD student on the IMPRS COMP2PSYCH programme researching the relationship between mood disorders and decision making using computational models. She is interested in how knowing about the valence of our future prospects interacts with our decisions, and our emotional response to the outcomes of those decisions. Do we make risky choices when the future looks good? Are we happier about the outcomes of those choices, even when we lose? Rachel explores these questions using probabilistic gambling tasks based in the laboratory, and developed for a smartphone platform for longitudinal data collection. She is particularly interested in how parameters capturing the influence of future prospects on behaviour and mood may change during onset of depressive episodes or during relapse, where negative future prospects may have a greater impact upon mood, even when current outcomes are positive. Rachel has an MSc in Cognitive Neuroscience from UCL where she was supervised by Neil Burgess and developed a computational model of how implicit racial bias is modulated by immersive virtual reality. After completing her MSc she was a research assistant with Anil Seth at the Sackler Centre, University of Sussex. Rachel has also previously worked as a research assistant in the Division of Psychiatry at UCL examining quality of life in people with moderate-to-severe dementia. She has a BA in Art and Psychology from University of Reading, and used to run the art and neuroscience public engagement company, AXNS Collective.

Bastien Blain uses computational modelling and neuroimaging to examine the relationship between experienced utility and decision making, and the role of emotions in decision making and learning. He did his PhD in Economics at Paris Panthéon-Sorbonne University under the supervision of Mathias Pessiglione and Guillaume Hollard. In his PhD research, he asked how cognitive fatigue, occurring after many hours of cognitive work (e.g., a workday), alters economic decisions
(e.g., the consumption-saving trade-off). Bastien has taught a course in neuroeconomics since 2013 for the Eco&Psycho Masters degree at Paris 1 Panthéon-Sorbonne.

Rasmus Bruckner’s current work focuses on the development of computational cognitive models and the application of these methods to behavioural experiments. He mainly uses a probabilistic modelling approach to better understand causes of individual differences in learning and decision making. In one line of research, he examines factors that explain age-related differences in the adjustment of learning rates in stochastic and changing environments. In more recent work, he investigates the computational principles that govern reinforcement learning under considerable perceptual uncertainty. In his future work, he would like to combine cognitive modelling with functional neuroimaging. Since 2015, Rasmus is a fellow of the International Max Planck Research School on the Life Course (LIFE). At FU Berlin, he works with Hauke Heekeren and Dirk Ostwald and collaborates with Matt Nassar (Brown University) and Ben Eppinger (Concordia University).

Simon Ciranka supervised people with disabilities in a work center before he enrolled at university. In 2011, he started his studies in Psychology at the University of Giessen and obtained his Bachelor’s degree in 2015. Here, he investigated the stability of perceptual priors in human visual processing using multistable motion stimuli. During his studies he spent 6 months abroad in Istanbul. Further he interned as a psychotherapist for half a year at the Psychiatry Department of the Charité University Hospital, Berlin. In 2015 he enrolled at the Cognitive Affective Neuroscience program at TU Dresden. For his Master’s thesis he reformulated a Switching Gaussian filter model of adaptive learning under uncertainty with the help of the Chair of Neuroimaging (Stefan Kiebel/Dimitrije Markovic). He then used this Bayesian account of reinforcement learning under the assumptions of the free energy principle to investigate age differences in social learning, supervised by ndrea Reiter and Shu-Chen Li. Since October 2017, he is a COMP2PSYCH fellow under the supervision of Wouter van den Bos. He investigates adolescents’ decisions under uncertainty and how and why these decisions are modulated by a social context.

Charles Driver runs the Intra-Person Dynamics Across the Lifespan project within the Center for Lifespan Psychology at the Max Planck Institute for Human Development. Charles completed his PhD on hierarchical continuous time dynamic modelling under the supervision of Manuel Voelkle, and is, in general, interested in dynamic systems approaches to understanding change. Because dynamic systems with respect to human behaviour and cognition are still not well understood, such an interest means that Charles is also engaged with statistical approaches for incorporating and understanding differences between subjects, accounting for model uncertainty, explorative analysis, and measurement concerns. Aspects of this work have been incorporated into ctsem, a software package for modelling with hierarchical stochastic differential equations within R.

Magda Dubois is a first-year PhD student on the IMPRS COMP2PSYCH programme at the Max Planck UCL Centre for Computational Psychiatry and Ageing Research. She is interested in investigating the neural and computational mechanisms underlying apathy, a common syndrome associated with multiple psychiatric disorders, and how it emerges during  development. In particular, she focuses on how this reduction of motivation during decision making is driven by an imbalance between the effort- and reward-learning pathways and how it is linked to the development of dopamine pathways during adolescence. She will investigate these impairments by combining computational modelling, neuroimaging methods and drug studies. Magda obtained her MSc in Biomedical Engineering at Imperial College London where she used deep reinforcement learning algorithms to automate the process of single neuron recognition in microscopy brain scans. Previously she completed her BSc in Bioengineering at EPFL in Switzerland, where she studied the role of predictability on the mechanisms of visual processing.

Samuel Ereira is an MBPhD student at UCL, investigating the computations that underpin cognition in both healthy people and in people with mental health conditions. He is interested in how the brain represents different models of the world and selectively attributes them to “self” and “other” for social cognition. He is also interested in how people can be trained on this process of self–other distinction. Sam began his higher education by studying pre-clinical medicine at Oxford University, where he undertook an intercalated BA in Neuroscience. After graduating, he moved to UCL to continue his clinical studies, where he was offered a place on UCL’s MBPhD programme, granting him the opportunity to interrupt his medical studies and do some full-time research. Sam started his PhD in September 2015, under the supervision of Ray Dolan and Zeb Kurth-Nelson. He also receives weekly clinical teaching from the UCL Medical School and on some weekends he shadows doctors in the emergency department to assist with clerking newly admitted patients. After he finishes his PhD and returns to medical school, he intends on specialising in psychiatry, whilst continuing to conduct his own research. When not doing science Sam likes going on cycling holidays, writing and listening to music and putting on comedy shows.

Douglas D. Garrett (PhD, 2011) is leader of the Lifespan Neural Dynamics Group (LNDG) within the Max Planck UCL Centre for Computational Psychiatry and Ageing Research, and is based at the Max Planck Institute for Human
Development in Berlin, Germany. Research within the LNDG examines how and why the human brain fluctuates so markedly from moment to moment. Perhaps counterintuitively, we continue to find that healthy, better functioning brains are characterised by greater signal variability across broad brain regions, cognitive domains, and task types. We examine brain signal variability and dynamics in relation to six core research foci: lifespan development, cognition, neuromodulation, structural/functional connectivity, transcranial stimulation, and modelling/methods. Accordingly, we have an inherent multivariate focus that allows the examination of brain signal variability phenomena across multiple levels of analysis.

In his research, Hauke Heekeren aims to understand the brain basis of motivated human behaviour: how we learn and assess the value of decision options, how we deliberate, how we choose. Humans have to make decisions each and every day, decisions that differ widely in their degree of complexity and the temporal scales within which they unfold. Some decisions are simple and effortless, such as deciding whether an approaching car will turn left or right, when to cross a busy street, or what to eat for lunch. Other decisions require long deliberation and can have life-shaping consequences, such as which career to pursue, where to live, whom to marry, or whether to take one’s medication. We investigate these different kinds of decision making using neurocognitive methods. Hauke is Professor of Biological Psychology and Cognitive Neuroscience at Freie Universität Berlin. He is Dean of the Department of Education and Psychology as well as Director of the Center for Cognitive Neuroscience Berlin (CCNB). Since obtaining his doctoral degree in 2000 for his work on neurovascular coupling, the major focus of his work has been human decision neuroscience. Hauke has received the Rudolph Virchow Award (2004) for excellence in research from the Charité (Humboldt-Universität zu Berlin) as well as an Emmy-Noether-Award (2005) by the German Research Council (DFG). He is the founding editor of the journal Frontiers in Decision Neuroscience and currently the Chief Editor of Frontiers in Human Neuroscience.

Alexandra Hopkins is a second-year PhD student on the IMPRS COMP2PSYCH programme at the Max Planck UCL Centre for Computational Psychiatry and Ageing Research. She is interested in investigating the learning and decisionmaking biases that are present in anxiety disorders. Why do anxious people make biased decisions and evaluations for themselves but not others? Are anxious people less optimistic and more realistic and does this realism bias contribute to poor mental health in general? How is inference biased by perceived near miss negative events? She is using computational modelling combined with neuroimaging methods and behavioural shock studies in order to understand the mechanisms underlying these biases and how they contribute to the maintenance of dysfunctional beliefs. Alex completed her MRes in Cognitive Neuroscience at UCL, where she was supervised by Dorothea Hämmerer and worked on a  neuroimaging study investigating locus coeruleus integrity in old age. She also has a BSc in Psychology with Neuropsychology from Bangor University, where she worked on a project investigating sensorimotor synchronization, and previously worked as a Research Assistant at UCL on a project investigating adolescent development.

Rogier Andrew Kievit studied Quantitative Psychology at the University of Amsterdam, receiving his PhD in 2014 with Denny Borsboom. He then moved on to a postdoctoral position with Rik Henson at the MRC-Cognition and Brain Science Unit (MRC-CBSU), working on the Cam-CAN study. Currently, Rogier is a Sir Henry Wellcome postdoctoral fellow at the Cognition and Brain Sciences unit in Cambridge, collaborating closely with UCL (Ray Dolan), the Max Planck Institute for Human Development (Ulman Lindenberger), the University of Cambridge (Ian Goodyer), and the MRC-CBSU (Rik Henson). His work concerns the neurobiological processes underlying developmental changes in executive functions across the lifespan. Specifically, he uses a variety of structural equation models, including MIMIC models, hierarchical factor models and longitudinal analysis to relate changes in cognitive abilities to changes in brain structure and function in large longitudinal datasets, with a particular interest in adolescence and old age. With the goal of understanding adolescent development and increasing neurocognitive health in older populations, Kievit’s particular interests are in models that effectively capture how cognitive changes across lifetime relate to brain reorganisation, maintenance, and compensation.

Niels Kloosterman is a postdoctoral fellow in Douglas Garrett's Lifespan Neural Dynamics Group at the Max Planck UCL Centre for Computational Psychiatry and Ageing Research, located at the Max Planck Institute for Human Development in Berlin, Germany. Niels is interested in the brain mechanisms and processes that transform subjective perceptual experiences into purposeful actions — perceptual decision making, in short. In particular, he likes to study how these mechanisms change with age and how the state of arousal affects decisions — for example, how decision making in drowsy and alert brains differs from each other. He uses visual and auditory perceptual tasks to study these topics, often combined with eye tracking and pupil size measurements as well as neuroimaging methods such as electro- or magneto-encephalography (E/MEG), or functional magnetic resonance imaging (fMRI). In his current work, Niels combines eye  tracking and fMRI to investigate how people view pictures of everyday scenes and how their viewing style is reflected in the dynamics of their brain activity. In another line of research, he uses psychopharmacology and MEG to study how the  arousal-related noradrenaline and dopamine brain systems affect the way in which we make basic perceptual decisions. Finally, in a further study he investigates whether the variability of neural signals measured with EEG could reflect a decision-maker’s subjective certainty about the occurrence of hardly visible perceptual events.

Julian Q. Kosciessa is a COMP2PSYCH fellow since 2016 and a member of Douglas Garrett’s Lifespan Neural Dynamics Group at the Max Planck Institute for Human Development. Prior to his doctoral training, he earned a BSc degree in Psychology at Freie Universität Berlin (2014) and an MSc degree in the Mind and Brain program (Brain Track) at Humboldt-Universität zu Berlin (2016). His interests concern the neural basis of selective attention and the flexible engagement thereof, particularly with regard to macroscopic neural dynamics. He further has a specific interest in characterising neural rhythms from single-trial electromagnetic recordings. He believes that a joint investigation of EEG and fMRI dynamics can provide mechanistic insights into the origin and functional role of different neural processing modes and their relevance for behavioural flexibility in complex environments. His current projects aim to provide insights into the role of the thalamus in cortical processing and cognition. For this purpose, he investigates putative changes in thalamic structure and function across the lifespan.

Rani Moran earned his BSc (1995–1998) and MSc (1998–2001) in Mathematics from the Hebrew University in Jerusalem. After completing his MSc, he worked in industry, including areas such as communication systems, algorithmic financial trading, and solar energy. During these years, Rani patented several inventions (e.g., efficient solar reflectors) and developed a keen interest in Psychology. He earned a BA in Psychology from the Open University of Israel in 2009 and later decided (much to the chagrin of his friends, colleagues and accountant!) to embark on a PhD in Cognitive Psychology (2011–2015) at Tel-Aviv University. In his PhD research, Rani used his expertise in mathematics and statistical inference to push forward our understanding of control processes in human decision making and episodic memory. After finishing his PhD, Rani joined the Max Planck UCL Centre for Computational Psychiatry and Ageing Research in UCL as a postdoctoral research associate. Rani's work has been published in both specialist (e.g., Psychological Review) and multidisciplinary (e.g., PNAS and Current Biology) journals. When he is not thinking about science, he'd probably say that he's reflecting on Literature, Music and Art — but don't be fooled, he is actually thinking about food and wine.

Matt Nassar’s goal is to understand how the brain prioritises, segregates and combines information collected in dynamic and complex environments and how this process differs across individuals, pathologies, and healthy ageing. For example, why and how do people prioritise sensory information arriving at  certain times or locations? How does the internal arousal state of the brain affect ongoing cognition and sensory processing? What functions might these dynamic fluctuations serve in the real world? Matt’s research addresses these questions by using computational models to link complex behaviour to changes in indirect measures of neural processing (fMRI, EEG, pupillometry) and to investigate computational differences across individuals, pathologies,  and the lifespan. One line of his research has used Bayesian models of change-point detection to (1) provide a normative explanation for learning  adjustments, (2) link implementation of learning adjustments to arousal systems, (3) identify distinct and anatomically localised uncertainty and surprise  signals, and (4) demonstrate that reduced learning in older adults is consistent with an under-representation of uncertainty. Another line of Matt’s research  has used information theoretic encoding models to understand how and why people combine specific features in working memory, how this combination may occur, and how differences in excitation/inhibition balance might affect the degree to which information is combined or separated in working memory.  Ongoing work is using magnetic resonance spectroscopy to measure individual and age differences in glutamate and GABA levels to test these predictions and understand the degree to which they contribute to agerelated changes in cognition.

Weisong Ong is interested in the basic mechanisms of social awareness and interactions. As social creatures, our everyday decisions are rarely made in a vacuum. Critically, deficits in social awareness and interactions are a hallmark of various psychopathologies, most notably in autism. To study the effects of social attention on social interactions, Weisong uses novel behavioural paradigms based on game theory to study cooperation in a setup that allows us to look at twoparty interactions and carry out intracranial neuronal recordings at the same time. This setup also allows us to study the changes of neural activity in response to oxytocin, which has been used therapeutically on individuals with autism.

Alistair Perry completed his PhD in 2017, under the supervision of Wei Wen (UNSW, Australia) and Michael Breakspear at QIMR Berghofer (Brisbane, Australia). His PhD focused upon the macroscopic changes in structural and functional brain networks that are tied to phenotypic differences in both normal ageing and psychiatric conditions, particularly those teased apart with multivariate analyses. Alistair’s interest has extended towards characterising the neural circuitry linked to interoceptive and reward-based processing. This has led to recent investigations of the neural mechanisms underpinning those with affective disturbances, and neurodegenerative disorders characterised by dopaminergic dysregulation. To address these important research questions, advanced neuroimaging methods have been leveraged, and implemented within translational settings (i.e. Deep Brain Stimulation).

Nicolas Schuck is the leader of the Max Planck Research Group NeuroCode – Neural and Computational Basis of Learning, Memory, and Decision Making. Before joining the Max Planck Institute for Human Development as a group leader, he was a predoctoral LIFE fellow at the Max Planck Institute for Human Development and Humboldt-Universität zu Berlin from 2010 to 2013, and a postdoctoral researcher at Princeton Neuroscience Institute from 2013 to 2017. He studies how memory and decision-making functions interact in the human brain. His work seeks to address questions about how humans use previous experiences to inform their future choices by applying computational models and pattern recognition algorithms to experimental data from functional magnetic resonance imaging (fMRI). This approach allows him and his team to decode the information hidden in the complex brain activation patterns of humans while they make decisions, and to understand which variables are encoded in different brain areas and in what way. Most recently, his work has focussed on investigating task representations in the orbitofrontal cortex and fast sequences of hippocampal memory representations (replay) in humans using fMRI.

Philipp Schwartenbeck is a postdoc at the Wellcome Centre for Human Neuroimaging (UCL), and Wellcome Centre for Integrative Neuroimaging (University of Oxford, UK), after completing a PhD in Cognitive Neuroscience at UCL and the Centre for Cognitive Neuroscience in Salzburg (Austria). His research focuses on computational models of decision making in behaviour and brain function. The focus of his PhD was to investigate the neural computations of inferring hidden states in the world and comparing different representations of the environment, as well as to understand how these processes might break in psychiatric conditions, such as addiction. Currently, he works on understanding the neural mechanisms of learning the structure of the environment, which provides the basis for inference on choices and states, and how individuals differ in these computations. He is particularly interested in how subjects learn and generalise abstract relational knowledge about the world.

Yuki Shimura is an MPhil student in the Computational Psychiatry programme at the Max Planck UCL Centre, London. She received her BA from University of California, Los Angeles, where she worked in the Social Cognitive Neuroscience Laboratory at UCLA that is directed by Matthew Lieberman. Following graduation, she spent two years at the Harvard Intergroup Neuroscience Lab working as a research assistant for Mina Cikara. Yuki aims is to understand how environmental conditions and subjective feelings modulate state-based learning and decisionmaking strategies, such as optimism or pessimism biases. Her current project describes the relationship between mood and learning and the link to optimism in healthy and depressed participants using a combination of computational modelling, large-scale smartphone-based data collection, and neuroimaging.

Wouter van den Bos received his MA in Philosophy, and MSc in Cognitive Neuroscience at the University of Amsterdam. He received his PhD at the Department of Psychology of Leiden University in 2011. From 2011 to 2013 he was a postdoctoral fellow in Psychological Sciences at Stanford University working in Sam McClure’s Decision Neuroscience Lab. He has been a visiting researcher at NCC lab in Princeton and the Institute for Human Development at UC Berkeley. Currently he is a Research Scientist at the Max Planck Institute for Human Development in Berlin, and a member of the Center for Adaptive Rationality (ARC). Wouter has a broad background in both neuroscience and developmental psychology and his research investigates the relation  between the developing brain and changes in behaviour during adolescence. More specifically, his research is focused on how changes in brain function  and structure relate to typical and atypical development of judgment and decision making. To approach these questions, he uses computational models and methods from experimental economics. These models are used to quantify behaviour and the complex processes underlying decision making. The parameters from these models support spanning of the bridge between developmental theories and neurobiology, and enable the identification of more specific processes that underlie developmental change. Using these techniques has enabled him to investigate the neurocognitive development of risky and intertemporal choice, social decision making, rewardbased and social learning. His work has been funded by the NWO, NIH, DFG and Volkswagen Foundation.

Diego Vidaurre is currently a postdoctoral researcher at the Oxford Centre for Human Brain Activity (OHBA), where he has been working since 2012. He isinterested in the development and application of computational methodology for characterising and understanding the complex dynamics of activity in the brain, and for relating these to behaviour in a meaningful way. In particular, he aims to combine data from different sources (fMRI, MEG, EEG, anatomical data) using novel modelling techniques and state-of-the-art machine learning technology. His goal is to use this computational approach to eventually gain new insights into disease mechanism, as well as exploring ageing and developmental processes. Diego obtained his graduate degree in Computer Engineering at the Rey Juan Carlos University, in Madrid, receiving the National Award in that year. After some years working on (non-academic) engineering, he obtained his PhD at the Polytechnic University of Madrid. His thesis explored the use of regularisation techniques in regression and supervised classification.

As a Research Associate at the Max Planck UCL Centre and WCHN, G. Elliott Wimmer’s research uses behaviour and functional brain imaging to look at the neural systems that support learning and decision making. In particular, his research looks at how both episodic memories for positive and negative experiences and well-learned value associations influence the choices people make in the future. Before joining UCL, at Columbia University, the UKE in Hamburg, and Stanford University, Elliott had identified interactions between the hippocampus and the striatum during learning and generalisation,  demonstrated how single rewarding episodes are reinstated to affect decision making, and established that long-term training is necessary to go beyond transient, working memory-supported reward learning to establish robust and lasting value associations. Currently at UCL, one of several projects focuses on understanding mechanisms of episodic memory replay for valenced experiences using MEG.
