I am a freelance archaeologist specializing in the medieval period. I have worked as a field archaeologist for the Department of Environment (Northern Ireland) and the Museum of London. I have been involved in continuing education for many years and have taught for the University of Oxford Department for Continuing Education (OUDCE) and the Universities of London, Essex, Ulster, and the London College of the University of Notre Dame, and I was the Archaeological Consultant for Southwark Cathedral. I am the author of and tutor for an OUDCE online course on the Vikings, and the programme director for the Oxford Experience Summer School.
