Before coming to Portsmouth, I taught for 15 years at Edinburgh University, where I was Co-Director of the ESRC Regional Research Laboratory and a Member of the Edinburgh Parallel Computing Centre.  In the 2004/5 Session I was Scholar-in-Residence at the Pennsylvania Historical and Museum Commission.
