About me

I am currently a senior lecturer in School of Electronic Engineering and Computer Science in Queen Mary University of London.

My research is focused on developing high-level logical and mathematical models for computer systems, learning their parameters from data, e.g. via machine learning, automating the reasoning using proof theoretic and algebraic tools, and applying the results to mainstream and industrial tasks. My current interest is Natural Language Processing (NLP), previously I led work on Multi-Agent Systems (MAS).

Groups: Joint leader of the natural language lab, Member of the theory group, Associate member of the cognitive science group.  

Topics of Interest: Compositional Distributional Semantics, Category Theoretical Models of Natural Language, Pregroup Grammars, Vector Space Models, Dynamic Epistemic Logic, Algebra, Coalgebra, Proof Theory, Verification of Multi Agent System Protocols.

News

17th of June 2019: I was awarded a Royal Academy of Engineering Industrial Scheme Fellowship for the second time! This will start in September and end for a year and I will work on “Cross Domain Unified Representations for Content Similarity” with the BBC R&D’s Chris Newell and Andrew McParland. We are going to find a representation for different types of information encoded in a programme (TV, Radio, News) so that they correlate with the viewers’ behaviours.

12th of June 2019: Our paper “A Type-Driven Vector Semantics for Ellipsis with Anaphora using Lambek Calculus with Limited Contraction”, has just appeared in Vol. 26 .Issue 2 the Journal of Logic Language Information. Thanks Roussanka and Michael for all their efforts.

May 2019: We accepted 13 submissions for our workshop Vector Space Semantics for Dialogue and Discourse in IWCS 2019! We have three keynote speakers, lightening talks, poster sessions, and a panel discussion. Check out the programme here.

May 2019: Watch the video of my colleague Sanjaye Ramgoolam from Centre for String Theory in QMUL, talking to the Plusmaths.org about joint work on the applications of methods from statistical physics to analyse natural language data.

10th of April 2019: Our paper “A Generalised Quantifier Theory of Natural Language in Categorical Compositional Distributional Semantics with Bialgebras” has just appeared online in the journal Mathematical Structures in Computer Science, check it out here.

27-28th of March 2019: I am chairing the third Symposium on Compositional Structures (SYCO 3) in Oxford. We have a very nice and even spread of topics on the theory and practice of category theory, do come by if you are around.

12th of March 2019: Our volume of papers, edited with Glyn Morrill, on Statistical and Logical Models of Meaning has just appeared as a special issue of Journal of Language Modelling. Check it out here.

22nd of February 2019: Our paper “Evaluating Composition Methods for Verb Phrase Elliptical Sentences: has just been accepted for NAACL 2019! I will talk about it in my invited talk in IWCS 2019 in May in University of Gothenburg!

31st of January 2019: I am giving a talk on our recent work on density matrices for entailment in compositional distributional semantics in Sussex’s Data Science seminar series today. The paper has appeared in Annals of Maths and AI, check it out here.

6th of January 2019: I have been invited to give a talk in MFPS XXXV-CALCO 2019, to happen in London in June 2019.

4th of December 2018: I have been invited to give an Evening Lecture in ESSLLI 2019 in Riga! Martha Lewis and I are also teaching a course on Vector Space Models of Meaning there, proceeded by an advanced workshop on applications of vector space models in different fields, see more here.
