Designed a novel type of gas flow proportional counter for detecting low energy X-rays. This was patented and marketed commercially.
- 1972-78 Co-initiated catalysis studies in Harwell with Dr R.S.Nelson. Designed a new range of catalysts, (based on novel Fecralloy® steel substrates) for vehicle exhaust emission control. These are described in a series of patents. The resulting products were licensed to Johnson Matthey Plc.
Co-founded the Harwell Catalyst Unit with Dr R.S.Nelson
Worked on the use of sol-gel technology for producing new catalysts. Promoted to Principal Scientific Officer.
- 1978-81 Set up research team to study the basic processes involved in using RF gas plasma discharges to etch silicon integrated circuits. Promoted to Banded Grade Scientific Officer
- 1981-88 Became Head of Applied Chemistry Group at the Harwell Laboratory. Responsible for directing research of approx. 50 scientific and technical staff on a range of topics, including catalysis, ceramics, and semiconductor materials. Collaborated with a wide range of industrial companies, including Johnson Matthey, Rolls Royce, and IBM.
Assumed responsibility for the fundamental research on Chemical Effects at Surfaces for the United Kingdom Atomic Energy Authority.
Promoted to Senior Staff- the highest scientific level in the UK Atomic Energy Authority.
- 1989-2001 Professor of Microelectronics and Materials Science at the University of Dundee.
