Professor Anthony Gachagan

Electronic and Electrical Engineering

Personal statement

Prof Gachagan has been Director of the Centre for Ultrasonic Engineering (CUE) since October 2010. This research Centre comprises approximately 55 staff and students and has a current funding portfolio of in excess of £5M. Prof Gachagan has line management responsibilities for all CUE personnel, reporting directly to the Departmental Head of Department. Interestingly, the research portfolio within CUE is diverse, with Electronic and Mechanical Engineers, Physicists, Mathematicians, Polymer Scientists and Biologists involved in the research teams. The research portfolio of the Centre has expanded in recent years, with robotics, metrology, bioacoustics and high power ultrasound building on the traditional fields of NDE and Sonar. Prof Gachagan has been directly involved in all of these areas and it is his interest in a broad, diverse range of scientific and engineering topics coupled with his strategic leadership that has seen CUE strengthen in terms of international profile, industrial engagement and funding profile.

Prof Gachagan is the Academic Chair and a member of the Management Board of RCNDE. He is also a member of both the Technical and Scottish Branch Committees of the British Institute of Non-Destructive Testing (BINDT). Within Strathclyde, he is the Deputy Head of Department for EEE, EEE Research Director and sits on the departmental Departmental Strategy Advisory Group and Departmental Executive Team.
