Profile

Dr Spiridon Siouris is a research fellow in aviation fuel and lubricant thermal stability in the Low Carbon Combustion Centre/Energy2050 group.

He studied Mechanical Engineering at The University of Sheffield where he graduated with an MEng in 2004 and received best thesis award from IMechE where he studied aerodynamic optimisation of blended wing bodies.

He carried out PhD studies at Sheffield in numerical modelling and experimental investigation of aviation lubricant thermal degradation and deposition, including reaction rate optimisation.

Since the completion of his PhD, Spiridon has worked in several research projects in the Low Carbon Combustion/Energy 2050 and Aerodynamics groups, dealing with aerospace fuel and lubricant degradation, aerospace elastomers, turbulence modelling, aerodynamic flow control, and plasma modelling.

He has worked closely with several academic institutions and industrial partners such as Rolls Royce plc and Airbus.

Through these projects, Spiridon has developed expertise in large scale experimental testing for aviation gas turbines, and numerical modelling for Computational Fluid Dynamics and aerodynamics.

Spiridon has also been involved in teaching activities for undergraduates and postgraduates, and also in the delivery of Computational Fluid Dynamics modules in Chemical and Biological Engineering between 2016 and 2018.
