Department of Applied Mathematics and Theoretical Physics

I am an EPSRC Early Career Research Fellow in the Waves group.

My research focusses on analytic prediction of the noise generated by aerodynamic structures in flow, with a view to developing novel surface treatments which permit noise control. Such treatments may include adaptations to the physical geometry of the structure such as serrations, or variation of the material properties of the structure by using specially designed acoustic metamaterials.

I currently supervise four of PhD students who work on different aspects of noise control analytically and with low-order numerical models.
