Current interests

Pierre Gélat is an expert in the mathematical modelling of acoustic and ultrasonic phenomena. His work has involved the simulation of hydrophone transfer characteristics; bubble dynamics; nonlinear wave propagation in heterogeneous media; finite element modelling of ultrasonic and audio transducers; and acoustic emission modelling. He has contributed towards characterising the NPL reference cavitating vessel and cavitation sensors, and aided the design of the new generation of foetal heart-monitoring transducers for Huntleigh Healthcare.

Biography

Pierre obtained the BEng degree in Elecroacoustics with First Class Honours in 1994 from the University of Salford, UK, and the MSc in Sound and Vibration Studies with Distinction in 1996 from the University of Southampton, UK. He then completed a research assistantship in conjunction with Peugeot-Citroën at the University of Southampton investigating vehicle engine vibration using statistical energy analysis and finite element methods. He joined NPL in 1997.

Pierre is also currently studying for a part-time PhD with University College London, investigating boundary element methods in view of modelling and optimising acoustic fields for ablative therapies of tumours in the upper abdomen.
