Pavlos Aleiferis studied Mechanical Engineering with a Diploma thesis in Computational Fluid Dynamics (CFD) and obtained a Master of Science (MSc) in Thermal Power and Fluids Engineering from the University of Manchester with a dissertation in turbulence modelling (1996). He then joined Imperial College where he studied for a PhD (1997–2000) and conducted postdoctoral research in optical techniques and numerical simulations applied to engine flows in collaboration with Honda R&D, Japan. Subsequently he moved to University College London (UCL) as a Lecturer in 2003, where he was promoted to Reader in 2011 and Professor of Thermofluids in 2015. In 2016 he was appointed as Chair in Thermofluids in Imperial’s Department of Mechanical Engineering. In 2013 he established with Jaguar Land Rover the JLR Centre of Excellence in Spark-Ignition Engine Research.


Pavlos's research is in the fundamentals of fuels and engine systems for low-carbon green vehicles. The focus of his work is both experimental and computational using Laser-based optical diagnostics and numerical modelling of turbulent multiphase flows. Research sponsors include the EPSRC, Jaguar Land Rover, Shell, MAHLE Powertrain, BP, Lotus, Ford, Delphi. Pavlos is on the Editorial Board of Fuel published by Elsevier. He has received prizes by the Combustion Institute (Sugden Award), the Institute of Physics, the Institution of Mechanical Engineers (Dugald Clerk Prize) and the Society of Automotive Engineers. Current projects and research interests include:

• Sustainable fuels and their properties.

• Sprays, cavitation, flash boiling, supercritical conditions.

• Turbulence and mixture formation in engines.

• Flame growth and cyclic variability under heavy dilution.

• Premixed compression ignition (CAI, HCCI, PPCI, GCI).

• Hydrogen direct injection and underexpanded jets.

• Lubrication and oil transport through piston rings.

• Engine efficiency, advanced propulsion systems.

Pavlos also maintains a strong interest in F1 engines and aerodynamics.
