My research is concerned with the process-microstructure-property relationships in structural materials. Engineering applications require materials to display a balance of mechanical and environmental properties, which can only be achieved by tailoring complex microstructures. Additionally, it is essential to determine the ability of these materials to advance from concept to production, as specific microstructures can only be obtained through sophisticated manufacturing processes. My work aims at optimising material properties, whilst ensuring their appropriate manufacturability using modelling and experimentation. I am interested in studying advanced alloys such as Ni- & Ni-Co-based superalloys, steels, titanium and magnesium alloys. 

Modelling and simulation of properties in metallic materials

The continuous demand for more efficient engineering components requires materials to improve their performance. For instance, more efficient gas turbine engines require designing high-pressure discs with higher temperature of operation. This results in Ni-based superalloys, materials employed in these components, not only holding high strength but also high creep and oxidation resistance. The use of mathematical modelling can help in identifying optimal microstructures for various properties. My work in this area consists in defining physics-based models linking microstructure with properties in modern structural materials. Classical theories describing deformation in pure materials or simple systems have shown limitations in their application to commercial alloys. 

Thermomechanical processing of engineering materials

My work in this area is focused in understanding and predicting microstructure evolution during the hot processing of metallic systems. A number of metallurgical processes operate simultaneously during the manufacturing of an engineering component. This includes recrystallization, grain growth, dislocation recovery and precipitation. I employ different simulation techniques to describe these processes. I am also interested in developing holistic approaches linking material process and component design using computational methods.
