ABOUT THE PRESENTER
Colin Humphreys is the Goldsmith’s
Professor of Materials Science at the University of Cambridge since
1990. He also serves as the Director of the Rolls-Royce-Cambridge
University Technology Center in Gas Turbine Alloys and also the
Research Director of the Joint UK-Japan International Research Program
on Atom Arrangement, Design, and Control for New Materials. He received
his B.Sc in physics, at the Imperial College, London and his M.A.
from Oxford University and Ph.D. from Cambridge University.
Prof. Humphreys has conducted creative and original work on semi-conductors,
ceramic super-conductors and inter-metallic compounds and has received
eight awards recognizing his contributions to the field of materials
science. He was awarded the Rosenhain Medal and Prize of the Institute
of Metals in 1989. He was Selby Fellow of the Australian Academy
of Science in 1997 and is a member of Academia Europaea.
He is the author of more than 350 publications and is a member of
10 UK National committees in the materials field. His breadth of
knowledge of materials research is reflected in his presence on
the Editorial Board of seven high quality international journals,
including Journal of the Physics and Chemistry of Solids and the
Journal of Materials Science – Materials in Electronics.
One of Prof. Humphreys particular skills is the communication of
the excitement and creativity in materials science to young people.
He is currently Fellow in the Public Understanding of Physics at
the Institute of Physics and is a member of the BBC’s Independent
Advice Panel on Engineering and Technology Programs. He has appeared
on television and radio many times to promote science and engineering.

Designing Materials: From Turbine Blades to Brilliant Light Emitting
Colin Humphreys, University of Cambridge
About the topic:
Our understanding of physics, chemistry, and materials science is now
sufficiently good that we can increasingly design and create man-made
materials to meet specific needs. This lecture will focus on two very
different examples of materials design. The first concerns complex, multi-element
structural materials for turbine blades for power plant, which are too
complex to be designed from first principles. The second shows how we
can design, from first principles, new semiconductor materials and devices
based on gallium nitride. These devices have a huge range of applications,
from traffic lights to home and office lighting to medical. Both examples
illustrate the huge economic importance of designing new and improved
materials, and also both examples demonstrate how materials science can
be used to reduce global warming.
