about
Hi! I am an Associate Professor of Computational Cognitive Science. I work in the Department of Cognitive Science and Artificial Intelligence in the Donders Centre for Cognition and the School of Artificial Intelligence at Radboud University in the Netherlands.
My research interests comprise (meta)theoretical, critical, and radical perspectives on the neuro-, computational, and cognitive sciences broadly construed. See my list of publications for more.
I am committed to equity, diversity, and inclusion in (open) science, promoting access to technical skills training — including the broader decolonisation of cognitive and computational sciences. Relatedly, Christina Bergmann and I maintain a list of underrepresented cognitive computational scientists.
biography
I emigrated from Cyprus to the United Kingdom in 2006 to pursue an undergraduate degree in Computer Science (2009; University of York, UK). After that, I moved on to an MSc in Cognitive and Decision Sciences (2010; University College London, UK). I then undertook a PhD in Psychological Sciences (2014; Birkbeck, UK), specifically on computational models for semantic memory.
Since obtaining my PhD, I have worked in labs at the University of Oxford, University College London, and as an independent scientist at an EU-funded research centre in Cyprus. In 2020, I moved to the Netherlands to work with Andrea E. Martin, before starting as an Assistant Professor at the Radboud in 2021 where I still work.
research interests
If you are interested in working with me, feel free to contact me. Prior to that, it might be worth taking a look at my group's website and at the following themes of research that currently interest me:
- Critical perspectives on AI, its history, its current state, including projects about artificial neural networks, sans hype (e.g. Guest, 2026; Guest & Martin, 2023, 2025b).
- Metatheory and metamethodology in neuro-, cognitive, computational, and psychological sciences (e.g. Guest, 2024).
- Human categorisation and models thereof from a perspective of what is lacking in our framing of this cognitive capacity (e.g. Natalia Scharfenberg's PhD project).
