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.

Research Opportunities

-I have a fully-funded PhD position in the Dept. of Aeronautics. 

The project is focused on Computational Fluid Mechanics, Nonlinear Hydrodynamic Stability Analysis and Control with a specific focus on high-speed flows as part of a collaborative effort between Imperial College (Dept. of Aeronautics) and ONERA (DAAA Meudon, France). More details hereDeadline for application: 8th July 2021 (or until filled).


- PhD. A scholarship is available at the Department of Aeronautics at IC. Interested applicants can contact me for more details on projects. See 'Aero Department Scholarship' at the department's website. Deadline: 1 March.

- PhD. Students with a strong track record in engineering/math disciplines are encouraged to apply for the IC President's PhD Scholarship. Three rounds, deadline: 8 Nov - 20 March.

- Post-doc. Various opportunities exist for fellowships at post-doctoral level from EPSRC, RAEng, Leverhulme, 1851, Marie Curie. More details and links here.
