Luca Reggio's Homepage

Since February 2022 I am Senior Research Fellow at University College London, where I work on Samson Abramsky’s EPSRC project “Resources in Computation”. Before that, I was a Marie Skłodowska-Curie fellow at Oxford University, where I carried out my project D-FINED. I am mainly interested in logic and its categorical, algebraic and topological facets.

Before moving to the UK, I was a postdoc researcher at the University of Bern, working on George Metcalfe’s project “Hidden Quantifiers”, and at the Institute of Computer Science of the Czech Academy of Sciences in Prague.

I obtained my PhD in Mathematics at Université de Paris in September 2018, under the supervision of Mai Gehrke. I spent the first two years of my PhD studies at IRIF (Paris 7), and the third one at the Laboratoire J.A. Dieudonné in Nice. In that period I held a scholarship from Sorbonne Paris Cité, and worked on Mai Gehrke’s ERC Advanced Grant DuaLL. My PhD thesis, entitled “Quantifiers and duality”, can be found on the Publications page.
