John Coull joined the Oxford Thermofluids Institute in 2019 as Senior Research Fellow in Gas Turbine Aerodynamics.

Dr Coull completed his undergraduate degree in Engineering at the University of Cambridge in 2005, before studying for his PhD under the supervision of Prof Howard Hodson at the Whittle Laboratory. He held the post of Rolls-Royce Senior Research Fellow at Magdalene College, Cambridge from 2010-19.

John’s research interests cover many aspects of turbine aerodynamics and heat transfer, including profile design, endwall loss, tip leakage flows and the impact of manufacturing variability. He uses combinations of experimental and computational approaches to tackle problems, in close collaboration with industry. In addition to this core research he has published widely on aerodynamic measurement techniques, in particular the design and application of Micro-Electro-Mechanical-Sensors (MEMS).
