Recently, I completed my PhD at the University of Southampton, where my research focused on the role of surface texture in the hydrodynamics of aquatic locomotion. This project advanced understanding of the multiscale interactions involved, addressing whether fish’s scales might actually make them better swimmers. I am joining Prof. McKeon’s group as part of the Shear Stress And Propagating Pressure measurements in High Reynolds number Experiments (SAPPHiRe) project. The project investigates the impact of large-scale fluctuations on sub-convective pressure and wall shear stress, advancing understanding of noise and drag in high Reynolds number settings. My research interest lies in resolvent analysis and its potential to form low-order representations of these phenomena.

Modelling the impact of large-scale fluctuations on sub-convective pressure and wall shear stress.
- **Project Focus:** Examining and modelling the impact of large-scale fluctuations on sub-convective pressure and wall shear stress.
- **Objectives:**
- Analyse linear and nonlinear contributions to sub-convective pressure fluctuations.
- Investigate the origin of sub-convective shear stress fluctuations, particularly wall-normal velocity gradients at the wall.
- Understand the spatial origins and underlying nonlinear interactions that excite these fluctuations.
- **Methodology:** Utilise a hybrid approach combining scaled mid-Reynolds number DNS results with high Reynolds number experimental data.Location
