Summary

 

Summary

I am a Lecturer in the Department of Aeronautics at Imperial College London. Before joining IC in 2019, I was a Postdoctoral Scholar at Caltech and the University of Cambridge. I received a Ph.D. in Aeronautical Engineering from Imperial College in 2015.   

My research focuses on engineering science and technology at the intersection of fluid mechanics, control, energy, and environment. I am interested in the fundamental understanding and control-oriented modelling of transitional and turbulent flows encountered in the aerospace and automotive industry. I am particularly interested in the development and implementation of active and passive control schemes, which reduce noise, aerodynamic drag, structural fatigue. Control schemes are evaluated through high-fidelity numerical simulations and state-of-the-art experiments at the Imperial Aero Wind Tunnel facilities.
