Personal Webpage of Ons RAMEH

I am a PhD student in Probability Theory under the supervision of Max Fathi.
My interests lie at the interface between Probability Theory, Analysis, and Statistical Physics.

Research Interests: Interacting Particle Processes, Mixing Times, Hydrodynamic Limits, and Fluctuations.
