Welcome on my web page ! I am a PhD student at Institut Fourier, under the supervision of Vincent Beffara.
I'm part of the 'Probability' group and I'm particularly interested in statistical physics, where I study models of interacting particles and percolation.
At the same time, I teach at Univ. Grenoble Alpes at undergraduate level.

Detailed CV.

Research

In statistical physics, we aim to understand the macroscopic behaviour of physical systems on the basis of microscopic interactions between particles. A particularly interesting phenomenon is the phase transition, which consists in an abrupt change in the behaviour of the system around a certain critical parameter (e.g. temperature). In 'real life', these include solid-liquid and liquid-gas transitions, as well as the so-called Curie point, which is the temperature at which a ferromagnetic material loses its magnetisation. Mathematically, this last phenomenon can be interpreted in the formalism of the Ising model, which is probably the reference model in statistical physics presenting a phase transition (in dimension d ≥ 2).
If the phase diagram of the Ising model is very well known today, it is mostly thanks to the existence of correlation inequalities of the 'FKG' type. In my PhD thesis, I am interested in non-FKG methods that can be applied to models that are not positively correlated, as is the case for Ising at negative temperature, the random-cluster model with q<1, or even disordered systems with the addition of random coupling constants, used to model spin glasses.

Teaching

Since 2021, I give a course for first year maths-IT students, about mathematical language, complex numbers, functions, sequences...
I am also teaching fellow of introduction to probability for second year maths and physics students.

I organise a working group at the Institut Fourier, in which every week (or so!) a PhD student from the probability team or an M2 intern presents a research article recently posted on arxiv, on various topics in probability. You can find the list of talks here.
On Philippe Caldero's youtube channel, you'll find a series of videos I made (in French) on the sensitivity conjecture, proved by Hao Huang in 2019, on the complexity of Boolean functions.

Miscellaneous

Here is a manifesto for limiting the use of planes in maths labs (in French), initiated by colleagues in Lyon and Grenoble.
