 Research Interests

Current project
I am currently working with Glynn Winskel on Events, Causality and Symmetry — the next generation semantics thanks to the European Research Council.
I am also involved with Ehud Lamm’s Conceptual Biology Lab.
Past projects
During 20132014 I worked with Peter Sewell on Semantic Foundations for RealWorld Systems, with close interaction with the participants of Rigorous Engineering for Mainstream Systems thanks to the Engineering and Physical Sciences Research Council.
During 20122013 I worked with Sam Staton on algebraic theories, computational effects, and concurrency, thanks to the Isaac Newton Trust.
During 20092013 I worked with Gordon D. Plotkin on my PhD thesis an algebraic theory of type and effect systems, thanks to the Scottish Informatics and Computer Science Alliance and the University of Edinburgh Informatics Graduate School.

2014
 PC member, 3rd ACM SIGPLAN Workshop on HigherOrder Programming with Effects (HOPE’14).
2013
Liberated Robin Gandy’s thesis On Axiomatic Systems in Mathematics and Theories in Physics from the trees.
This deed was made possible with the kind help of Martin Hyland, the eager consent of the copyright holder, the literary executor Mike Yates, and the generous financial support of Barry Cooper.Coorganised the Haskell Symposium’s ``Future of effects in Haskell’’ panel with Sam Lindley.
Coorganised the Agda Course in Cambridge with Dr. Dominic Orchard.
Liberated algebra valued functors in general and tensor products in particular by Prof. Peter Freyd from the trees.
I was unable to obtain Prof. Freyd’s permission to put this scan up, but the book that included it did not contain any copyright notice. If you know I am infringing on his copyright, please let me know.
2011
 Liberated Algebraic Theories (1969) by Prof. Gavin Wraith from the trees.
With the kind permission of Prof. Wraith, this scan of his Aarhus University Lecture Notes can be freely circulated. A 2upped version.  Organised the SICSA Agda Course by Conor McBride.
