Profile

I am a research associate in the Thermofluids group. My research focuses on computational modelling of boiling heat transfer in nuclear reactors.

I hold an MEng in Aerospace Engineering from the University of Sheffield, graduating with first-class honours, and also studied at the Aerospace Department at the University of Michigan, USA, as part of a Global Engineering Exchange program. I recently completed my PhD at the University of Sheffield in data-driven turbulence modelling. My PhD research focused on combining Computational Fluid Dynamics (CFD) with machine learning techniques to enhance turbulence models, particularly for improving the prediction accuracy of complex aerodynamic flows.

Research interests
  • Computational fluid dynamics
