Welcome to my home-page.

I am a Research Associate within the Theory and Semantics Group of the Computer Laboratory, University of Cambridge working on the ERC Project ECSYM. I am also the Director of Studies in Computer Science at Emmanuel College. I completed my PhD titled Petri net semantics in 2009 under Glynn Winskel and am currently working on the relationship between process logics and independence models.  I have also previously worked at ENS/INRIA in Paris with Jérôme Feret and, long ago, was a student with Philippa Gardner at Imperial College. My specific interests include:


Set Theory for Computer Science - MPhil ACS course. Michaelmas term 2010-11.

Topics in Concurrency - Part II course. Easter term 2010-11. Lent term 2012-13, 2014-2016

Advanced Topics in Concurrency - MPhil ACS course. Easter term 2010-11.
