I am a Cognitive Scientist examining how people make decisions. I studied Computer Science (BSc, Athens, 2006), then completed an MSc (Edinburgh, 2007) and a PhD in Cognitive Science (UCL, 2008-2012). I was a postdoc with Chris Summerfield at University of Oxford (2012-2015), held a Wellcome Trust Career Development Fellowship at Birkbeck (2015-2016), and pursued a Marie Curie IF in Tobias Donner's lab at UKE Hamburg (2016-2018). I led an ERC Starting Grant (2018-2024), initially at UKE  and then at Bristol, where I moved as Senior Lecturer/Associate Professor (2021-2025). In 2025, I joined the Institute of Neuroscience & School of Psychology at Trinity College Dublin as Research Professor, where I lead an ERC Consolidator Grant project.

PhD student co-supervised by Sean Froudist-Walsh investigating how perceptual decision making may depend on brain structure differences cross species. Previously in Tim Behrens’ lab working on TDLM and compositional planning in humans.

My research investigates how people weigh information and make decisions under uncertainty. In particular, I focus on how priors, preferences, and goals guide decisions, and on the metacognitive monitoring of those decisions, combining psychophysics, computational modelling, and MEG. I completed my PhD with Elisa Filevich at HU Berlin, where I examined the role of priors in perceptual decisions and confidence. As a postdoc with Floris de Lange at the Donders Institute, I extended this work to curiosity-driven information sampling, asking how priors, uncertainty, and expected information gain shape what we choose to learn. At the Irrationality Lab, I investigate how preferences dynamically shape multi-attribute decisions and confidence.

I am a computational cognitive scientist interested in attention, memory, and decision making. I use generative models of behavioural and neural data, together with Bayesian methods, to investigate the mechanisms underlying these cognitive processes. I have undergraduate degrees in Psychology and Law (Groningen, 2014-2018), an MSc in Cognitive Neuroscience (Amsterdam, 2020), and a PhD in Psychology supervised by Clay Holroyd and funded by the Flemish Research Foundation FWO (Ghent, 2021-2026). As a postdoctoral researcher at Trinity College Dublin, I will investigate the dynamics of changing preferences during decision making.
