I am a Royal Society University Research Fellow in the Laboratory for Foundations of Computer Science, University of Edinburgh, working in the areas of databases and programming languages.From September 2004 until October 2008 I was a postdoctoral research associate in the Database Group. I have also been involved with the Digital Curation Centre and during 2008-2009 I organized a Theme Program on Principles of Provenance for the eScience Institute. From January to May 2003 I visited Cambridge University's Computer Laboratory. In the summer of 2001 I worked at Intertrust on a summer internship.
