The world little knows how many of the thoughts and theories which have passed through the mind of a scientific investigator, have been crushed in silence and secrecy by his own severe criticism and adverse examination.

Welcome to my webpage!
I have recently started a permanent position at ONERA The French Aerospace Lab after one year of post-doctoral research within the same institution and after having completed my PhD in Mechanics at EPFL.
During my PhD in the Laboratory of Fluid Mechanics and Instabilities, I have worked on the theoretical modelling of self-sustained dynamics and forced resonant oscillations in various flow problems ranging from cross-junction jets to liquids sloshing.
Specifically, I have used linear stability analysis and asymptotic techniques to provide comprehensive theoretical frameworks based on reduced models, such as amplitude equations, that can rationalise some of these complex nonlinear oscillatory dynamics. To achieve this, my work drew upon direct numerical simulations and dedicated experiments, which were performed and designed in collaboration with other experienced researchers.
More info will be available soon under Research & Tutorials.
Background
After obtaining my Scientific High School Diploma in 2013, I left my hometown, Narni, located in the heart of Italy, and I moved to Pisa for a Bachelor’s Degree in Aerospace Engineering until 2016. During my Master’s Degree in Aeronautical Engineering at Università di Pisa, I had the pleasure of attending the course Computational Fluid Dynamics (CFD) held by Prof. Simone Camarri, who quickly made me passionate about CFD. He played a significant role in my moving to Lausanne in September 2018, where I first met Prof. François Gallaire, who introduced me to the fascinating field of hydrodynamics instabilities during a seven months Research Internship at LFMI-EPFL. Such a stimulating experience pushed me to join again LFMI in 2019 for a 4-years PhD in Mechanics, which I completed in September 2023.

In this @PhysRevFluids paper, we quantify numerically the Stokes drift and Eulerian viscous streaming contributions to the Lagrangian mean flow generation, offering new insights into orbital sloshing wave dynamics beyond traditional inviscid models. https://t.co/NuAUddtgr1 pic.twitter.com/Zk8YXd4u27

Check out our @PhysRevFluids paper, where we present a physics-inspired mathematical model based on linear eigenmode projections to solve the nonlinear relaxation dynamics of liquid oscillations with hysteretic contact line motions. @lfmi_epfl @APSphysics https://t.co/oJEOmBp9YN pic.twitter.com/CqPtX7suUF

Our @JFluidMech paper proposes a gap-averaged Floquet theory that considers inertial effects. We reveal a modified damping coefficient affecting the wave response and emphasise the significance of accounting for frequency detuning. @lfmi_epfl #OpenAccess https://t.co/z4yyGfQL6B pic.twitter.com/eyG0zE2Rwq

Planar, irregular and swirling motions are well-known features of longitudinal resonant sloshing. A. Marcotte, F. Gallaire and @BongarzoneAle showed how nonlinearities trigger similar dynamics far below the first natural frequency. @JFluidMech #OpenAccess https://t.co/7JFjwEuAKB pic.twitter.com/tWIwQV5DWu

Give your next cup of coffee/tea a swirl and watch the liquid dance around. You might expect the sloshing waves to move in the same direction as the swirling. Here. Marcotte et al. show the counterintuitive case where they move in the opposite direction! https://t.co/ng5uV1Xgbw pic.twitter.com/UMvK4VFhTK

PRFluids Editors' Suggestion: A Von Kármán vortex street is a classic image of fluid dynamics: from water passing a bridge pier to winds blowing around small islands. Here, Lombardi et al. demonstrate the effect of permeability on vortex shedding. More @ https://t.co/JDJbLHFktO pic.twitter.com/LI5V2MgWRe
