Chris Gaffney was appointed to the staff at Bradford in October 2007. His link with Bradford goes back to the 1980s as he undertaken both undergraduate and postgraduate degrees at this university. Having completed doctoral research (in Earth Resistance) Chris formed a commercial archaeological geophysical company with John Gater. GSB Prospection became the largest group working in Britain. In the summer of 2007 Chris was awarded an Honorary Doctorate for popularising archaeological geophysics via Time Team and other media opportunities. He teaches both undergraduate and MSc students as well as developing commercial avenues in prospecting. Over the last two decades I have researched and published on many aspects of Archaeological Science. The articles reflect his interest in topics as diverse as geophysical prospecting, philosophy of science, TL dating, Trace Element Analysis and commercial aspects of prospecting.
