Biography

Biography

Dr Tizzard joined Middlesex University in 1986 when it was Middlesex Polytechnic. He was previously a Teaching Company Associate with Imperial College and Phillips (UK) Ltd working on an innovative automated television assembly line. Prior to that he was a Manufacturing Engineer and then a Design Engineer with a Ministry of Defence contractor. During that time he worked on a number of projects including Nimrod ground replay systems and early thermal imaging devices.

His first degree is in Mechanical Engineering from Brunel University with Biomedical Engineering Specialsm in the final year. He gained a masters from Imperial College in Computing and his PhD from Middlesex.

He is a Chartered Engineer with the Institution of Engineering Designers.
