tl;dr
My name is Antonin Callard. I am a second-year PhD student at Université de Caen (France) under the supervision of Pascal Vanier. I am in the AMACC team of the GREYC lab.
I study symbolic dynamical systems (e.g. subshifts) based on their computational, dynamical and topological properties. For my PhD, I try to understand some computational similarities between subshifts and group theory.

Some background
I studied theoretical computer science at ENS Paris-Saclay between 2018 and 2021. During my studies, I completed research internships with Mathieu Hoyrup (2019), Pascal Vanier (2020) and Benjamin Hellouin de Menibus (2021). I graduated from M2 MPRI during summer 2021, and I was a research visitor supervised by Ville Salo at the University of Turku (Finland) for the academic year 2021-2022. I feel deeply indebted to all of my previous advisors for their very kind supervisions.
I started my PhD at Université de Caen (France) in September 2022. My research focuses on subshifts which are deeply fascinating objects that I study through a computational lens. Aside from (un)decidability results and somewhat creative constructions, it has lead me to consider finitely and recursively presented groups, as some group invariants (related to growth) seem to exhibit interesting computational parallels to entropies of subshifts.
Random trivia
Outside of research, my interests lie in movies, books, music, tabletop and video games (Celeste, Outer Wilds and Hollow Knight are all awesome, by the way), (Void) Linux-related stuff, long walks and (even longer) discussions with friends. I have deep gratitude for those who indulge with me in the time-consuming yet very enjoyable activities. 😃
