Ph.D. in Mathematics Currently postdoc at @bonsaiseqbioinfo.bsky.social, in Lille. Investigating patterns (substructures) in structured data (sequences, trees, graphs) of predominantly biological origin. More at https://fingels.github.io/
PREPRINT ALERT I heard you craving for more combinatorics, here are some more for y'all !
Florian Ingels, Antoine Limasset, Camille Marchet, Mika\"el Salson: Vigemers: on the number of $k$-mers sharing the same XOR-based minimizer https://arxiv.org/abs/2602.03337 https://arxiv.org/pdf/2602.03337 https://arxiv.org/html/2602.03337

Preprint Alert! We present new strategies to accelerate large-scale document comparison using MinHash-like sketches. A thread:
Compressed inverted indexes for scalable sequence similarity https://www.biorxiv.org/content/10.1101/2025.11.21.689685v1
Preprint alert! We introduce new ideas to revisit the notion of sampling with window guarantees, also known as minimizers. A thread:
Minimizer Density revisited: Models and Multiminimizers https://www.biorxiv.org/content/10.1101/2025.11.21.689688v1
His book "Mathematica" is a real eye-opener. David Bessis describes accurately and vividly the way we perceive and manipulate mathematical objects. Colleagues who read it also felt he put into words what they had not been able to formulate about the mathematical process. Highly recommended.
The mathematician David Bessis believes that mathematical skill is not innate, but learned. “Genius is not an essence. It’s a state. It’s a state that you build by doing a certain job.”
Okay, #SeqBim is over, let's get crackin' and speak about our recent preprint (joint work with @imartayan.bsky.social, Lucas Robidou, @camillemrcht.bsky.social and @npmalfoy.bsky.social) 1/

Wait ! That's me !
And now Florian Ingels present multiminimizers and various results about density at #Seqbim Once again thread (I'm pretty late) incoming and for those you absolutely can't wait the preprint is already out if you want to spoil yourself :p
Slowly converting innocent colleagues to the joy of using LaTeX fonts in matplotlib. Soon, they will be ready for Tikz.
Un article très intéressant, qui montre que la très grande majorité des salariés trouvent que l'IA générative n'a pas d'utilité pour leur travail (voire que ça produit de la merde), alors que les chefs ont des attentes souvent irréalistes www.blogdumoderateur.com/ia-generativ...
IA générative : 97 % des entreprises peinent à prouver sa valeur business
Toutes les entreprises, ou presque, peinent à prouver la valeur business de l'IA générative. Malgré cela, 87 % des organisations annoncent une hausse de leurs investissements.

Stay tuned 👀 More combinatorics is coming
🎶 Last Christmas,i gave you m̶y̶ ̶h̶e̶a̶r̶t̶ 40 pages of delicious combinatorics 🎶 Choose any word W of size m. How many words of size k>m admit W as their smallest lexicographical subword of size m ? Find out in my latest preprint!
Absolutely phenomenal video about the links between artistic creativity and mathematics (also, combinatorics and enumeration, which are kind of my brand) This video really captures what I like doing when doing combinatorics www.youtube.com/watch?v=_BrF...

Achievement unlocked: defend your habilitation thesis on the same day than your partner. That was quite a science + celebration day, thanks to all involved 💙✨
can’t stop imagining Good Will Hunting but instead of solving graph theory problems on the blackboard he’s writing stuff like 4+3=7
Hi, I am a mathematician in a movie. I have written some non-sense equations on my (black)-board, will use fancy terms that are supposed to make me look smart, and will probably serve as a caution that whatever magical thingy happens in the movie is actually science.
Hi, I’m an highschool teacher in a movie. I start my class with a random question on a topic I’ve never discussed before so the new girl can show off. Then if I say something relevant about the main conflict, the bell rang and the students leave even if the class started 5 minutes ago.

I do not recommend staying up late until 3 a.m. because your brain can't accept that you can postpone solving that one collegue's problem he sent you via email during the evening and that you read around midnight but it's solved!

NEW PREPRINT OUT arxiv.org/abs/2506.04926 The Burrows-Wheeler transform of a string is, in general, more compressible than the original string, especially when it contains lots of repeated subtrings. The extended BWT allows to deal with multisets of strings. 1/7
Decomposing Words for Enhanced Compression: Exploring the Number of Runs in the Extended Burrows-Wheeler Transform
The Burrows-Wheeler Transform (BWT) is a fundamental component in many data structures for text indexing and compression, widely used in areas such as bioinformatics and information retrieval. The ext...
