Research interests
My main research interests lie in probability, especially its interface(s) with combinatorics or (not xor) statistical Physics. More concretely, most of my work is on stochastic dynamics and discrete probability. Namely, I primarily study interacting particle systems and probabilistic cellular automata. Currently, I am working on kinetically constrained spin models and the closely related bootstrap percolation, as well as on dimer model dynamics.
Open access statement
As a general rule, the last (or latest) version of all my papers can be found on arXiv. I generally do not display the published version anywhere, but instead use the final manuscript. I recommend reading the latter over the former, as it has the same content and is often better typeset. For that reason I disregard publisher price when submitting and encourage institutional libraries to invest in good printers instead of journal subscriptions.
Abstracts may differ from venue to venue due to length/citation restrictions. I recommend systematically using the one in the pdf of the latest arXiv version.
My papers can also be found below if I have updated my page recently enough. I only deposit them on HAL once they are published, so please refer to arXiv. I do not deposit full texts on ResearchGate or other platforms to avoid violating publisher copyright.
