Hello,

I am Arnaud, an academic at the crossroad between applied mathematics, physics and mechanical engineering. Between 2013 and 2024, I was an associate professor at the department of mechanical engineering of Sorbonne Université, Paris, France, conducting research at Institut Jean le Rond d'Alembert. Detached from Sorbonne since 2024, I am currently an invited associate professor in the Department of Mathematics at MIT, Cambridge, MA, USA.

Together with students and colleagues, I use mathematics, numerical methods, and model experiments to study stability problems in dynamical systems, wave mechanics, and elasticity. I’m especially interested in how geometry and mechanics interact in slender elastic structures, in phenomena such as dynamic stabilization, band gaps, and nonlinear couplings in systems whose properties vary in space or time. A key part of my research is Floquet theory, where I see many opportunities to uncover and explain new mechanisms in physics and engineering.
