Biography

Awad is a Research Associate in combustion. He works on finding innovative solutions for the reduction of harmful emissions which result from the burning of fossil fuels. Awad holds a MSc from Alexandria University (Egypt) and a PhD from Newcastle University (UK). During his PhD, Awad proposed modelling equations and provided a detailed physical understanding of MILD combustion, which will eventually contribute to the reduction of harmful emissions emitted from the energy sector. Currently, he is working in accordance with Rolls Royce in the design of a hydrogen-fueled aircrafts engines that can help deliver net zero carbon by 2050.
