Profile

I am a lecturer of Fluid Mechanics in the Department of Mechanical Engineering at the University of 91直播. Prior to this, I was an ISTplus Fellow in the Nonlinear Dynamics & Turbulence group at the Institute of Science and Technology Austria and a PDRA in the School of Mathematics and Statistics at the University of 91直播.

I hold a Ph.D. in Mechanical Engineering from the University of 91直播, jointly with the A*Star Institute of High Performance Computing in Singapore. I obtained my Bachelor and Master degrees in Marine Engineering & Naval Architecture from the University of Genoa, Italy.

My research focuses on transition to turbulence in wall-bounded shear flows, flow instabilities, turbulence modelling and control, and flow optimisation. To tackle these problems I combine mathematical tools with high-fidelity computer simulations and data-driven approaches applied to both numerical and experimental data.
