I graduated with a first class honours degree in Mathematics from Liverpool University in 1991. I then went on to do a PhD in Mathematical Ecology 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. In January 2013 I started a new role as Professor of Aquatic Food security. We set up the Centre for Aquatic Food Security which is a virtual interdisciplinary centre which looks at the role of Seafood in the wider food security picture. More recently I have led the University Research Programme on Global Food Security which brings together colleagues from across the University who are applying their research to problems in food security. In April 2019 I took on the 0.4FTE role of Institutional Dean of Research Engagement and Performance alongside my departmental role. In my Dean role I am keen to ensure that we provide a positive and collaborative research environment which helps all people to reach their potential. I am currently President of the Edinburgh Mathematical Society.
