Peter Excell is Professor of Communications and Deputy Vice-Chancellor at Glynd┼Ár University, whose predecessor he joined in September 2007.He was previously at the University of Bradford, where he had worked since 1971 and where he obtained his PhD. He obtained his first degree (BSc Engineering Science) at the University of Reading and then spent six months at the University of Ife in Nigeria.He has industrial experience as a consultant to the oil and gas industry, working on assessment of hazards due to electromagnetic fields, and to the computing and mobile phone industries, working on electromagnetic interference and safety assessments.

His managerial brief at Glyndwr University is to deputise for the Vice Chancellor at both internal and external events as appropriate.More generally, he aims to apply his broad university experience to strengthen the academic culture, motivation and morale of staff and to project the enthusiastic, innovative and dynamic culture of the University to external audiences.

In addition, he maintains his own research work in electromagnetic fields, antenna design and mobile applications, and he also delivers some teaching through specialist lectures and through supervision of projects at levels from bachelor to PhD. The research work is verified in a continuing steady output of publications, of which he has produced about 450 over his career.

He chose to come to this part of North Wales because his mother was from this area and he drew immense strength and richness from the Welsh half of his family:he had a great aunt in Corwen who was a very early example of a woman who got a university degree and she was a powerful force for education in the family.

He speaks German and Italian reasonably fluently and also has a more limited knowledge of Russian and Welsh.

What do you like to do in your spare time? You don't get much spare time as an academic, but such as I get is mostly spent writing up my research and career experience. However, see below.

What are your hobbies/interests? I would say "real engineering". The preserved steam railways of North Wales are major attraction for me: they have built themselves up to be world leaders in their field and they constitute a great educational resource that I would like to see developed more. The traditional engineering skills that are maintained by them at, in particular, Llangollen and Porthmadog are a wonderful resource and the bedrock of the advanced stuff that we pursue in our research. At a personal level, my corresponding activities are looking after my antique Land Rover and my late father’s model railway.

I also have a deep interest in traditional Welsh music, especially the traditions of the Cymanfa Ganu (four-part harmony hymn singing in chapels) and Plygain (a folk carol tradition going back many centuries).

What’s your favourite animal? / Do you have any pets? No pets now: it wouldn't be fair to them, given modern work pressures. We used to have Scottie dogs when I was young: they were fun - small but incredibly tough. I used to enjoy riding horses, but haven't had time for it for a long time.

What’s your favourite book? The Ascent of Man by Jacob Bronowski. Long out of print, it was linked to his television series of the same name. He was a wonderful man who showed how science and technology could be combined with interest in the arts and humanities, thus bridging "the two cultures".

Fill in the blank: If I won the lottery I would… Probably use it to try to build confidence in Welsh culture and what it can contribute to the world.

Inspirational quotes? "Er gwaetha pawb a phopeth, Ry'n ni yma o hyd!" (Dafydd Iwan)

"Return unto thy rest o my soul, for the Lord hath dealt bountifully with thee; I will lay me down in peace and sleep until I awake in the morning of the Resurrection" (Inscription on the tombstone of Joseph Priestley, known as the discoverer of oxygen, among many things, and frequent visitor to Wrexham)

What’s your favourite film? The Gospel According to St Matthew by Pier Paolo Pasolini.

Which career would you choose to go into if you weren’t in this job? Traditional engineering, e.g. on the Ffestiniog Railway.
