I am an associate professor (Maitre de
confĂ©rences) at Ecole Normale Superieure (ENS) and a
researcher at the Laboratory of Physics of ENS
(LPENS), in the Nonlinear Physics group.

Since September 2020, I am a junior member of the
Institut Universitaire de France (IUF), and I am
entitled to supervise research [HDR] since 2018.

Aside from research, I teach fluid dynamics,
instability, statistical physics and experimental
physics (undergraduate and master).

# Research interests

My research focus on non-linear and statistical physics, mostly within the framework of fluid mechanics. In particular, my current research interests lie in the field of magnetohydrodynamics, i.e. the study of the dynamics of electrically conducting fluids. I combine laboratory experiments, theory and numerical simulations to study various phenomena such as flow instabilities, magnetic field generation, dynamical systems, chaos, pipe flows and turbulence. Below are some typical examples of my current interests:

## Waves and instabilities

## Astrophysical Fluid dynamics

## Turbulence

## Chaos and nonlinear dynamics

Waves are ubiquitous in both nature and industrial
systems. Most of the time, they are closely related to
the generation of instabilities in the flow. We use
laboratory experiments to study the stability of such
flows and the associated wave dynamics

Astrophysical fluid dynamics deals with the
application of fluid dynamics to the motion of fluids
encountered in space, such as planetary or stellar
interiors, accretion disks and galaxies. Thanks to the
growing amount of telescope observations and space
missions in recent years, whole sections of the theory
of such flows are now actively debated. In our group,
we combine laboratory experiments, theory and numerical
modeling to understand the mechanisms involved in some
of these astrophysical systems

The study of turbulence is one of the most active
research area. We developed several laboratory
experiments in order to adress various questions
related to turbulence, like the transport properties of
turbulent flows, the dimensionality of turbulence or
its statistical properties.

In several physical problems, a modelization using a
few coupled differential equations is very useful to
understand the non-linear dynamics of complex
systems. I am interested in fluids dynamics situations
in which a low dimensional behavior is observed,
despite the apparently large number of degrees of
freedom. It is still unclear why and how some very
complex and turbulent systems can be correctly
reproduced by extremely simple models.
