Dr Peter Armitage obtained a BSc degree in Engineering in 1976 from Middlesex Polytechnic. After working for a number of years in geophysical research and exploration world wide (mainly Antarctica, Europe, Indonesia and Africa). he continued his studies at the University of Wales Institute of Science and technology obtaining a post graduate diploma in Electronics in 1986, specializing in communications and Electro-Magnetic theory.

After a few years developing Geophysical and advanced Sonar instruments, returned to study and obtained a PhD in Engineering, Computing and Mathematics from the University of Exeter in 2009, for work involving the application of non-linear acoustic methods to detect defects in metals and composite materials. This research led to a spin off company at the university and the foundation of Theta Technologies Ltd.
