Biography

I am a Greek computer scientist, having my DPhil thesis with title "Compositional Distributional Semantics with Compact Closed Categories and Frobenius Algebras" just submitted at the University of Oxford. My research is focused on Computational Linguistics, and specifically on Compositional-Distributional models of meaning. Before Oxford I've been working for many years as a software engineer and a translator/editor of CS textbooks and scientific journals. I have an MSc in Artificial Intelligence from the University of Edinburgh.

Collaborators

While in Oxford I mainly work with Mehrnoosh Sadrzadeh; I also collaborate with Stephen Pulman, Bob Coecke, Edward Grefenstette, and Nal Kalchbrenner. In the past I worked with Mark Steedman and Panagiotis Kanavos.
