Assaad Masri is currently an ARC-Australian Professorial Fellow in the School of Aerospace, Mechanical and Mechatronic Engineering, Faculty of Engineering at the University of Sydney and Chairman of the Australia and New Zealand section of the Combustion Institute. He is internationally known as a leading scientist in turbulent combustion of gaseous and liquid fuels and laser diagnostics in combustion. He is on the editorial board of three prestigious journals and a founding member of the International Workshops on Measurements and Computations of Turbulent Nonpremixed Flames (TNF) as well as the International Workshop on Turbulent Combustion of Sprays (TCS). He has published over 150 papers, attracted over eight million dollars of research funding and established one of the most advanced combustion laser diagnostics systems in the world.

The burning of fuels to produce useable energy is a very old process but one that is not yet perfectly efficient, as it also produces waste and pollutants. Professor Assaad Masri leads a team of researchers who are working to devise methods leading to 'clean' combustion - both of fossil fuels and of renewable fuels such as biofuels and biodiesels - thus improving energy-conversion efficiency and reducing the emission of pollutants from engines, industrial furnaces and other combustion devices. "When we introduce new fuel alternatives into the market, we need to ensure that these fuels can be burnt efficiently, safely and cleanly, in that they do not produce harmful emissions such as nano-sized particles that will have negative long-term health effects. "My colleagues and I design burners that allow us to better understand turbulent combustion and hence devise tools that assist engineers to achieve this. "Numerous burners that we have designed are now used by both industry and academia as international benchmarks for developing and validating advanced predictive methods for combustion. "Our research uses the latest numerical tools in conjunction with state-of-the-art experimental laser-based techniques to probe flows. We work with laboratory flame as well as engines, and are also researching methods of developing micro-combustors that can be used for micro-power generation. "Our aim is to transform combustion science in order to facilitate the optimisation of combustors by design engineers."
