About

I am a PhD researcher in experimental fluid dynamics at City St George's, University of London. Working within the National Wind Tunnel Facility’s Gaster Low-Turbulence wind tunnel, I investigate the behavior of laminar separation bubbles.

My research concentrates on the effect of sweep on boundary layer transition.

I primarily utilise hot-wire anemometry and pressure measurements to characterise bubble topology and behaviour. Beyond my core research, I have developed a broader experimental background through projects in other facilities, including the departments transonic wind tunnel, employing a wider range of diagnostic techniques across different flow regimes.
