Hi! I am Antonin Callard and I am a postdoctoral researcher in symbolic dynamics and its connections to computability and complexity theory. I am currently part of the MC2 team at the LIP laboratory (ENS Lyon, France). If you want to learn more about me (or get my email address), you can visit this page. If you want to read my personal blog, you can go here. In any case, welcome!

Spring is always a beautiful season, but this year it is also applying-to-assistant-prof times! Fortunately, there is still some science to keep my sanity intact: with Léo Paviet Salomon and Pascal Vanier, we developed sufficient conditions for the soficity of multidimensional shift spaces. They are phrased in terms of $S$-adic shifts, in which the increasingly large alphabets of the intermediate substitutions allow to quantify the amount of “useful information” in the configurations of a shift. This is a much more flexible formalism for the second half of my thesis, and a preprint is available here!
Before submitting it, we would like to improve the paper by gathering feedback: if you are interested by computational topics in symbolic dynamics, and have anything you think would improve these results, please send us an email!
