I am a PhD candidate in the Department of Aeronautics at Imperial College London, supervised by Prof. Yongyun Hwang. I work on data-driven resolvent analysis of coherent motions in wall-bounded turbulence.

Research interests

• Resolvent analysis of turbulent shear flows under the triple decomposition framework
• Data-driven modelling: optimal forcing/response pairs extracted from DNS via phase averaging and a generalised eigenvalue problem
• Eddy-viscosity closures for the linearised operator — including anisotropic, component-dependent corrections to isotropic models
• Coherent structures and the self-sustaining process across scales in wall-bounded turbulence
