### About Me

I am a PhD student in computational statistical physics under the direction of Gabriel Stoltz and Tony Lelièvre at CERMICS (École des Ponts) and MATHERIALS (INRIA Paris). Relevant topics include:

- overdamped/underdamped Langevin dynamics
- sampling of probability measures in high dimensions
- Markov Chain Monte Carlo methods (Metropolis-Hastings, Hamiltonian Monte Carlo)
- numerical analysis
- non-equilibrium systems: perturbed dynamics with non gradient flows, linear response, transport coefficients, computing free energy differences
- numerical integration (Julia)

Other topics I am interested in:

- machine Learning techniques
- solving PDEs/SDEs
- numerical tools for scientific programming

I transcribed in LaTeX some mathematics exercices (and answers) that I prepared during my studies (L2 or CPGE MP* level in France). Everything is in French (and there are definitely typos here and there). Content: abstract algebra, differential calculus, matrix calculus, linear differential equations, euclidean spaces, normed vector spaces, functions of a real variable, integration, inner product spaces, probabilities, matrix reduction, series, power series, sequences and series of functions.

An ongoing project is also to transcribe in LaTeX the physics course I followed the same year (L2 or CPGE MP* level in France). Everything is in French (and there are definitely typos here and there, again). Content (for now):

- Mechanics: non-inertial reference frames, friction between two solids
- Electromagnetism: electromagnetic field, electrostatics, magnetostatics, electric dipoles, Maxwell equations, electromagnetic energy, waves in a vacuum, dispersion and attenuation of waves
- Thermodynamics: open systems, heat transfers
