Alexis Langlois-Rémillard
Hausdorff postdoc at the Hausdorff Center for Mathematics, Universität Bonn
Since October 2023, I am a Hausdorff postdoc at the Hausdorff Center in Mathematics in Bonn under the mentorship of Eveliina Peltola.
From May 2023 to September 2023 I was a postdoc at Center for Scalable Data Analytics and Artificial Intelligence (ScaDS.AI) Leipzig, Universität Leipzig, and a visitor at the Max-Planck-Institut für Mathematik in den Naturwissenschaften, Leipzig, Germany.
From April 2019 to April 2023, I was a PhD student at Universiteit Gent under the supervision of Hendrik De Bie, Roy Oste and Joris Van der Jeugt. My thesis was on the representation theory of the Dunkl total angular momentum algebra.
From September 2014 to January 2019, I did my bachelor and master degrees at Université de Montréal, the latter under the direction of Yvan Saint-Aubin with a thesis on the representation theory of seam algebras, a generalisation of Temperley-Lieb algebras.
Where will I be in the near future?
In July 2025, we are organising a CIMPA school in Ouagadougou, Burkina Faso website of CIMPA.
For the rest, outside conferences and trips, I will be in Bonn from October 2023 to 2025+.
Research interests
I am interested in: algebra, representation theory, mathematical physics. More specifically, I study and work with: diagrammatic algebras and categories, centraliser algebras, rational Cherednik algebras, reflection groups, Dunkl operators, Lie (super)algebras, and Temperley-Lieb algebras. I have also recently been interested in complexity theory and extremal combinatorics through chess-inspired mathematical problems.

News from 2023 onwards (old news)
2024/11/18 Our preprint Insights from a workshop on gamification of research in mathematics and computer science written with Élise Raphael and Érika Roldán is available arXiv:2411.10207! It is an exploration of the idea of using game to let people experience mathematical research and initiate a feedback loop to contribute to it in the best scenario. It goes over some example and present the experience of collective creation of a gamification instance that happened in Les Diablerets in October 2022 at the conference Let's talk about outreach!

2023-09-08 My Master student Stijn Dezeure successfully defended his Master's thesis titled Moving towards practical quantum decoders for the classical-quantum channel. Srdan Lazendic and me were his mentors for his Master's thesis under Prof Aleksandra Pizurica.
2023-09-01 Our preprint The double dihedral Dunkl total angular momentum algebra with Marcelo De Martino and Roy Oste is finally out online arXiv:2308.16366! It extends the last part of my PhD thesis in which we focus on the representations of the TAMA for two dihedral group, using a subalgebra admitting a triangular decomposition to give out necessary condition for finite-dimensional representations.
2023-08-31 I was in Nyon until 18 September and was travelling around Switzerland for research and work.
2023-08-01 My next conference in 02-11 August 2023 will be the LMS-Bath Summer School and Symposium on Geometric and Categorical Representation theory, Bath, England Summer School website and Workshop website.

2023-01-21 Our mini-course webpage is up! You can visit this relay page for more information, or go directly register on the website https://sites.google.com/view/kleine-seminar-mini-course/home.
2023-01-17 My PhD thesis has been submitted! The internal defence will take place on the 06 March 2023. It is bad form to plan the public defence before the end of the internal, but let's say it would be wise to keep the 24 April free would you want to attend my public defence.
Public fundings
I believe that we, as researchers receiving public fundings, should be transparent in their management. My first step in this direction is to disclose the funding received below (with more details in my CV).
My current funding is by a Hausdorff postdoc position. Starting from March 2024, I also hold a 2-year postdoctoral scholarship from the Fonds de Recherche du Québec -- Nature et technologies (grant number 326641). Previous fundings include:
My postdoc at Leipzig was funded with financial support by the Federal Ministry of Education and Research of Germany and by Sächsische Staatsministerium für Wissenschaft, Kultur und Tourismus in the programme Center of Excellence for AI-research „Center for Scalable Data Analytics and Artificial Intelligence Dresden/Leipzig“ (project identification number: ScaDS.AI).
My PhD research was publicly funded by the Fonds de Recherche du Québec - Nature et technologies (grant number 270527) and from the Excellence in Science research project PRIMA (grant number 30889451).
My Master's thesis was funded by the Fonds de Recherche du Québec - Nature et technologies and the Natural Sciences and Engineering Research Council of Canada.
Mundane and trivia
I pronounce my first name Aleksi but also quite like Alexeï. I speak French, English, Dutch, and I am learning German; you can contact me in any of these languages. I pass the time, amongst other activities, by reading, writing, playing chess, learning languages, starting random hobbys, and swimming. Topics that might make me speak for too long include: typography, government systems, the late medieval European period, the Cathar heresy in Occitan, chess history, books, Émile Zola, Québec gins, Belgian beer, Simone de Beauvoir and stories from Dwarf Fortress.
