Hi! I'm Pier Giuseppe Ledda

I am a Tenure-track Assistant Professor at the University of Cagliari, Italy. I obtained my PhD degree at the Swiss Federal Institute of Technology in Lausanne (VD), Switzerland.

My research focuses on fluid flows governed by complex boundaries and interfaces. In these systems, free surfaces, geometry, microstructure, permeability, and solid deformation can fundamentally alter transport and trigger nonlinear behaviours, instabilities, and bifurcations. These effects can also be harnessed as mechanisms for flow control. I combine mathematical modelling, numerical simulations, and experiments, mostly at small scales, to uncover the physical mechanisms and key parameters governing these phenomena. My goal is to derive reduced, predictive laws that capture the essence of these complex flows and can be transferred across biological, engineering, and environmental contexts.

Core research themes

Permeable and microstructured interfaces: Homogenization, transport around and through microstructured bodies, interactions with surrouding aerodynamic flows, passive flow control.

Free-surface and thin-film flows: rivulets, drops, bubbles, coating problems flows over complex geometries.

Soft hydraulics: fluid-elastic instabilities, deformable boundaries, snap-through, buckling, passive flow control.

Application areas: Biological and biomedical flows, environmental fluid mechanics.
