Research Themes

As Mitsubishi Heavy Industries (MHI) Senior Research Fellow, I am based at the Whittle Laboratory, part of the Department of Engineering, and I research new technology for power and propulsion applications such as electricity generation and zero-carbon flight. The aim of my work with Mitsubishi Heavy Industries is to make large compressors used in power generation more efficient, flexible and reliable so they can be used in the zero-carbon energy transition. We do this by studying the complex flow phenomena found in compressors using experimental tests performed at the Whittle Laboratory and at MHI’s R&D centre in Japan, and with computational simulations run on the University’s supercomputer.

Alongside this work, I co-lead a group at the Whittle Laboratory working on “electric jet engines” for future, zero-carbon flight. This work is supported by the UK government and a British SME, called Green Jets, who we are collaborating with to commercialise this new, exciting technology.

Away from power and propulsion, I am very interested in the aerodynamics found in sport and have recently finished supervising a PhD on “The Aerodynamics of Cricket Balls Swing”.


Teaching is an important part of my work and something I hugely enjoy. I currently supervise Girton undergraduate engineers in first year Mechanics and Thermofluids, and second year Mathematics. I am also the second year Director of Studies for Engineering and I lead Engineering Admissions for Girton.

I give lectures for the CDT in Future Propulsion and Power and MPhil in Energy Technologies and I supervise fourth year Masters Projects and PhDs.


Away from work I enjoy playing hockey and cricket (though I’m starting to slow down…) and I’m involved in coaching, umpiring and administration with Cambridge University Hockey Club (CUHC).
