John Chew

John Chew has been awarded a five-year Research Fellowship from the Royal Academy of Engineering. John's Fellowship will allow him to develop and extend the technique of fluid dynamic gauging (FDG). This technique exploits carefully controlled fluid flows to study the behaviour of soft surface films immersed in a liquid environment, such as protein gels, biofilms and swollen polymers. John's PhD work with Bill Paterson and Ian Wilson developed the technique of fluid dynamic gauging measuring film thickness in real time to study film strength and rheology, applying it to study fouling layers of food materials, mineral scales and in polymer reactors. The fellowship will allow him to develop the technique further, both in studying surface rheology of soft solid materials, developing FDG devices and combining the technique with the imaging technologies available in the Department. Applications in medical devices, biopolymers and biofilms are planned.

Iain Burns has been elected to a Research Fellowship at St. John's College to begin in October 2005. This will allow him to continue his research in the Department on the development of diode laser systems for gas phase sensing. Such instruments are being used to probe turbulent reacting flows, for example in flames and engines. Iain's PhD research, supervised by Clemens Kaminski and Johan Hult, involves the development of a device, based on blue diode lasers, for measurement of combustion temperatures with high temporal and spatial resolution. He is planning to travel to Sweden in May 2005 to apply this sensor to making measurements in a running diesel engine. The fellowship is for three years.
