Professor John Denton

After earning his Ph.D. in the UK in 1967, John was a lecturer at the University of East Africa, Kenya. He returned to the UK in 1969 and worked at the Central Electricity Generating Board, the main UK electricity utility.

In 1977 John became a lecturer at the University of Cambridge, based at the Whittle Laboratory. He undertook research on the aerodynamics of gas and steam turbines and continued the development of numerical methods, which became widely adopted around the world. He also supervised much experimental work.

John was promoted to Reader in 1989, Professor in 1991 and was Director of the Whittle Laboratory from 1984 to 1990 and again from 1999 to 2005. He retired from the University of Cambridge in 2005, but continues working as a consultant, and developing and using numerical methods.

Graham Pullan

Graham is a Professor of Computational Aerothermal Design at the University of Cambridge.

He obtained his MEng degree from Cambridge in 1997 and since then he has been based at the Whittle Laboratory, first during a PhD project, then as the Rolls-Royce turbines Research Fellow and now as a University Lecturer.

With strong links with industry Graham's work is grounded by real-world experiences and design challenges. His research is focused on the three-dimensional design of turbomachinery and on the computational methods required to achieve it.

Tobias Brandvik

Tobias is a Director of Turbostream Ltd. He obtained his MEng degree in 2007 and his PhD in 2012, both from the University of Cambridge. From 2012 to 2014 he was a Research Fellow at the Whittle Laboratory, where his research focused on how to best use emerging multi-core architectures for scientific computing.

His work at Turbostream Ltd is focused on the practical application of the computational power of multi-core processors to real design settings.

Alex Cranstone

Alex Cranstone is a CFD and aerodynamics specialist at Turbostream. He obtained his MEng degree in 2007 from the University of Cambridge and his PhD in 2012 for research into aggressive turbine design methodologies at the Whittle Laboratory.  

After graduating, Alex worked in fan aerodynamics at Rolls-Royce before joining Turbostream in January 2013.

Ewan Gunn

Ewan Gunn obtained his MEng and PhD degrees from the University of Cambridge in 2011 and 2015, respectively. His PhD research focused on fan-distortion interaction in novel aircraft configurations, combining experimental research with large-scale CFD calculations.

Ewan joined Turbostream in April 2015 after obtaining his PhD and works as an aerodynamics specialist.


Neil Paul

Neil Paul obtained his MEng from the University of Cambridge in 2014. 

Neil joined Turbostream in January 2020 where works as an aerodynamicist who specialises in simulations which feature conjugate heat transfer and fluid-structure interaction.

John Otter

John Otter obtained his MEng from the University of Cambridge in 2014 and his PhD from Cranfield University in 2018. During his PhD, John investigated propulsion system integration with a particular focus on the aerodynamic performance of separate-jet exhaust systems. From 2018 to 2021 John worked as a Research Associate at the Whittle Laboratory, University of Cambridge, where his experimental and computational research explored the impact of non-ideal gas dynamics on transonic turbine performance.

John joined Turbostream in March 2021 as  an aerodynamicist and he specialises in simulating turbomachinery that features non-ideal gas dynamics.
