Michael Kelly has been the Prince Philip Professor of Technology since September 2002. This is a new post to honour the 25 years service of Prince Philip as Chancellor of the University of Cambridge. He is also a Fellow of Trinity Hall and a Visiting Professor at the University of Surrey. During 2003-2005 he was also the Cambridge Executive Director of the Cambridge-MIT Institute, and 2006-9 he has been part-time Chief Scientific Advisor to the Department for Communities and Local Government. Since 2006 he has been a non-executive director of the Laird plc.


He came to the UK from New Zealand in 1971 to complete a PhD in solid state theory at Cambridge, and stayed there for a decade researching the electronic structure of metal and semiconductor surfaces and of amorphous materials. Between 1981 and 1992, he was based at the GEC Hirst Research Centre. His main research interests there concerned the practical exploitation of quantum transport phenomena in semiconductors, in particular in the area of new generation, high performance, microwave devices. Between 1992 and 2002 he was Professor of Physics and Electronics at the University of Surrey, first in the Department of Physics, and then heading the School of Electronics, Computing and Mathematics from 1996-2001, stepping down to Direct the Centre for Solid State Electronics in the School.


He is a Fellow of the Institute of Physics, Institution of Electrical Engineers, the Royal Society, the Royal Academy of Engineering and an Honorary Fellow of the Royal Society of New Zealand. He is a Chartered Physicist and Chartered Engineer. In 2002, he was awarded DSc (honoris causa) from his alma mater, Victoria University of Wellington. In 2006 he was awarded the Royal Society’s Hughes Medal and Prize for his work on electronic transport that became exploited in new semiconductor devices for advanced systems. In 2009 he was elected a member of Academia Europaea.


During his time advising Government, he became aware of the size of the challenge to retrofit today’s buildings, 87% of which will form 70% of the UK building stock in 2050, to meet the challenges of energy security, sustainable consumption and resilience to future climates. Recently he served on the Oxburgh Review of the climate science at the University of East Anglia and on the Royal Society revision of its public statement on climate change.


Research Interests


At present he is examining the manufacturability (or otherwise) of whole families of devices that rely on tunneling effects and on hot electron injection, and the use of ion-implantation in fabricating novel devices in semiconductor multilayers.


Teaching Interests


At present he teaches a final year option on advanced electronic devices, but has taught electrical science to first year electrical engineering students, statistical mechanics to final year physicists and calculus to first year mathematicians.
