I graduated with a first class honours degree in Mathematics from Liverpool University in 1991.I then went on to do a PhD jointly supervised by Roger Bowers in the Mathematics and Mike Begon in the Ecology departments funded by a Wellcome Trust prize studentship. I spent a year in Oxford Zoology department modelling the dynamics and control of Lymphatic filariasis. I started work as a lecturer in the Mathematics and Statistics group in Stirling in 1996 and went half time in 2001. I was promoted to Senior lecturer in 2003 and to Reader in 2010.
In January 2013 I started a new role as head of the new Aquatic Food Security Group. Reserachers in the Insititute of Aquaculture have been working on sustainable production of seafood for many years. The aim of the new group is to work with different groups in the Institiute and consolidate Stirling's position as world leading in Aquatic Food security research.
