Main areas of research

My research is primarily concerned with applied aeroacoustics & aerodynamics. I aim to gain a physical understanding of the noise-generating flow mechanisms, develop improved noise prediction models, and lead to the application of innovative noise mitigation solutions in aircraft.

Specific research interests are:

Airframe noise signature abatement
Drone noise modeling
Cavity flow and noise control
Bio-inspired aerodynamics/aeroacoustics
