    How are humans able to combine concepts to form new ones? Why do unexpected (or ’emergent’) attributes arise in these combinations? I am using computational linguistics, conceptual spaces theory, and category theory to try and answer questions like these.

    This work is funded by my Veni fellowship on the project Metaphorical Meanings for Artificial Agents.

    Before the ILLC, I was a postdoc in the Quantum Group in the Department of Computer Science, University of Oxford, under the project ‘Algorithmic and Logical Aspects of Meaning’ funded by AFOSR. I did my PhD at the University of Bristol, in the Bristol Centre for Complexity Sciences, and before that the EASy MSc at the University of Sussex.
