I am a Lecturer in Fluid Mechanics in the Department of Mechanical Engineering having joined at the end of 2021. I received a Bachelor of Science in Energy Engineering and a Master of Science in Nuclear Engineering from Politecnico di Milano, in Italy, where I also completed my PhD in 2013. Before joining the University of Sheffield, I was a postdoctoral researcher at the University of Leeds from 2013.
My research addresses mainly the development of computational models of the thermo-fluid dynamics of multiphase flows, with a specific focus on computational fluid dynamics and boiling flows. I am interested in nuclear thermal hydraulics and the prediction of boiling heat transfer, passive cooling and two-phase thermal hydraulic instabilities in reactor systems, and the fluid dynamics of bubbly flows in multiple devices. I currently hold an EPSRC Fellowship focused on the challenge of modelling multiple flow regimes and transition in gas-liquid flows.
