Capabilities:
Extensive background in solving problems for industry
including transfer of technology from lab to full industrial scale-up. Geoff was an early
pioneer of the use of ion implantation for the fabrication of silicon chips as well as ion
beam treatment of metals and the use of semiconductors as radiation detectors.
- Type of work: Technology development, innovation;
project management
- Technical areas: Ion beam based processes, advanced
materials, physics and its application to materials. Geoff holds 71 patents in a
wide variety of fields relating to metals, semiconductors, ceramics and polymers together
with their surface-related properties including friction, wear, corrosion, catalysis and
biocompatibility.
Background:
- Fellow of the Royal Society of London
- Vice President, Materials & Structures Div., Southwest Research
Institute, San Antonio, Texas
- Chief Scientist, Surface Technologies Branch, AEA Technology, Harwell
Laboratory, UK
- More than 300 publications; two books.
- Education: BA and PhD (Physics), Cambridge University, England
Some representative projects:
- Development of a new form of diamond-like carbon (DLC) for low wear,
low friction coatings. The coatings are biocompatible and used to reduce wear in
orthopedic devices. The low friction DLC coatings also seal pores and strengthen anodic
oxides on aluminum, and have been successfully tested on heavy duty diesel camshafts.
- Head of a major program on development of metal, oxide, nitride or
carbide ion beam-assisted coatings. Such coatings are now applied in medical devices,
optical components, precision valves for nuclear power industry, etc.
- Design and construction of full-scale industrial equipment, some of
which is the largest of its kind in the world. Geoff is experienced in design projects and
modification of existing plant.
- Development of methods using ion beams for quantitative surface
analysis, with specific applications in nuclear reactors (corrosion analysis), studies of
hydrogen contamination in titanium, and studies of wear in coatings on medical devices.
- Development of catalytically-active coatings for fuel cells giving
superior electrical performance.
