about
Hi! I am an Associate Professor of Computational Cognitive Science at Radboud University in the Netherlands.
My research comprises (meta)theoretical, critical, and radical perspectives on the neuro-, computational, and cognitive sciences broadly construed. See the publications section below or my group's website 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 am originally from Cyprus and all my higher education took place in the United Kingdom. I hold an undergraduate degree in Computer Science (2009; University of York, UK), an MSc in Cognitive and Decision Sciences (2010; University College London, UK), and a PhD in Psychological Sciences (2014; Birkbeck, UK) on computational models for semantic memory.
Since obtaining my PhD, I have worked at the University of Oxford and at University College London, as well as for 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).
