Expert is a multidiscipliarian managing development & commercialisation from start-ups to sales in electronic displays, lamps & electronic materials. He has spent nearly a decade developing hot, cold & sintered cathodes for gas discharge lamps including use in signage, automotive lamps, avionic LCD back lights & analytical instruments at Masonlite & Cathodeon. He worked also on field emission cathodes for CRTs & field emission displays/lamps leading an industrial consortium with Oxford University, & also on carbon nanotubes for clients. Cathode work included ruggedisation, low noise designs, production troubleshooting & patents.

In terms of commercialisation, he has over 20 years experience winning new business by developing new products & presenting them to customers. Thus, he brought Lite Array, Inc. into worldwide sales of thin film electroluminescent display modules, & also developed OLED displays there winning the Eastman Kodak license & contributing to the business plan that led to establising a pilot plant in China using a novel method for reducing cost. He has prepared & presented proposals winning government funds at Smiths Industries, & avionic display contracts at Ferranti interfacing customers such as British Aerospace & Embraer in deals worth $9m (using novel features such as universal fitting for cost reduction or active contrast filters). Several products were developed & improved at Cathodeon for lamps & laser applying new techniques such as advanced cathode designs & methods of sealing. At Lite Array & Ferranti he prepared sales brochures, product specifications, company brochure & press releases; also he managed the web site & participated in international exhibitions.

Regarding competitive intelligence, he has monitored competitors & their technologies whilst at Lite Array & BBV Digital including prices & performance. As an example he found new blue LEDs as an opportunity & threat for billboard video displays subsequently visiting suppliers in Taiwan & China securing LED modules as second generation products. He also compared OLEDs & thin film electroluminescent technologies for medical & industrial instrument markets. Another example was the analysis of the window of opportunity for a gas ion laser compared to products from existing players, & ROI possible before replacement by solid state lasers.

Product development of devices over 20 years included CRTs & flat panel matrix displays such as LCDs, EL, OLEDs & VFDs for industrial, automotive, avionic & medical instrumentation.
