Denis Politis holds a Master of Engineering (2010) and Ph.D. (2014) degree from Imperial College London. His background combines engineering design, modelling and experimental testing to develop laboratory technologies for industrial applications. Research interests include the use of forging and sheet metal forming of lightweight components for the automotive, aerospace and commercial sectors. Research laboratory work includes the investigation of the effects of temperature, speed, tooling and material contact conditions as well as process modelling to identify defects in part production and reduce manufacturing time, material consumption and cost. Dr Politis has published more than 70 articles in peer reviewed journals and conference proceedings and has worked on research projects in collaboration with industrial companies that have been sponsored by European FP7 and H2020 grants.
