I graduated from the University of Leeds in 1982 and completed a postgraduate Diploma in Cartography at the University College of Swansea in 1983. I then joined the staff at Portsmouth as Map Librarian and became Head of the Geographical Information Services Unit in 1987 before my appointment as lecturer in 1991. I was awarded my PhD in 1996 and was made Principal Lecturer in 1997.

Research Interests

My recent research has concentrated on the application of GIS to the study of landscape evolution with a specific focus on the analysis of historical landscape change in the Rother valley of West Sussex. I have particular interest in using archival material to reconstruct past landscape with a view to infroming policy on landscape restoration projects. I have published and presented several papers on the application of GIS to the study of agricultural productivity in the nineteenth century using a variety of modelling techniques. I am currently working on the tithe surveys of West Sussex in collaboration with West Sussex County Record Office, South Downs National Park and the National Trust.

I have also published works on the history of cartography in the twentieth century, particularly international mapping. I have contributed to the Exploratory Essays Initiative funded by the National Science Foundation of America on the history of cartography in the twentieth century. I was a major contributor to Volume VI of the History of Cartography edited by Mark Monmonier which was published by University of Chicago Press in May, 2015. I have also published papers with Prof. Michael Heffernan of Nottingham University on the globalisation of cartography during the 20th century.
