Interests

I am interested in the broad idea of composition: how parts make up a whole. My favourite tool to study this phenomenon is the mathematical field of category theory, with a particular emphasis on monoidal categories and their cousins.

At the moment, my research focuses on giving an algebraic account of how graphs, simple combinatorial objects made up of vertices and edges between them, compose. Using finitely presented PROPs I am trying to formulate a convincing syntax for open graphs whose models can shed light on various essential graph-theoretic notions: decompositions, factorizations, vertex-colorings, flows etc.

-----

In my master's thesis I investigated the mathematical structure of contextuality and ambiguity in various models of linguistic meaning. I tried to clarify how meaning emerges out of composing discourse fragments (from words to sentences, sentences to text) and how we resolve ambiguity by refering to a broader context (from text to sentences, sentences to words). 

Biography

After a degree at HEC Paris I studied mathematics at Université Pierre et Marie Curie (Paris VI) and completed a masters degree in computer science at the University of Oxford. My MSc. thesis explored models of lexical ambiguity in compositional distributional semantics.
