A few words about me¶

Greetings traveler, and welcome to my website! I am Lilian Besson, teacher-developper in Computer Science, and I was an assistant professor at ENS de Rennes from 2019 to 2021. I am now a full-time professor of Computer Science in Classes Préparatoires, in charge of the MP2I class at Lycée Kléber, in Strasbourg in France.

Before occupying these teaching-focused positions, I pursued my PhD in Telecommunications and Machine Learning in CentraleSupélec in Rennes and Inria in Lille, and I graduated in Mathematics and Computer Science at ENS de Cachan, with a Master degree in Machine Learning, and a Master degree in teaching Mathematics (along with « agrégation », the French national exam to become a civil servant teacher).

From August 2019 to August 2021, I was a junior professor (agrégé) at ENS Rennes, in charge of the class preparing the « agrégation » national exam, with a major in mathematics and a minor in computer science, level M2, and in charge of lectures for introduction and advanced algorithms, and other teaching activities.
In February 2021, I had fun adding these applications there on my site, to be able to write small codes, give quick explanations without having to install anything on his computer: ocaml.besson.link for OCaml 4.12, jscpp.besson.link for C/C++, python.besson.link and notebook.besson.link for Python 3.8, turing.besson.link for Turing machines, and tableaunoir.besson.link for an interactive and super functional blackboard! Note: I did not develop these applications myself, they are all free under the MIT or GPLv3 license.

I was also an associate researcher with the PANAMA team at IRISA in Rennes. My research interests were on innovative technologies for modern teaching, Python and OCaml programming, machine learning in general, and other directions.

Between September 2016 and August 2019:

I was pursuing my PhD at CentraleSupélec (SCEE team, IETR lab) in Rennes (France), with Christophe Moy and Emilie Kaufmann (SequeL team, CRIStAL lab, at Lille). My PhD was on multi-players multi-arms bandits models applied to radio-telecommunication, especially I-o-T problems. I now hold a PhD in telecommunications. My PhD thesis is here and the slides used for my defense are there.
And I was teaching theoretical computer science at ENS Rennes (for a class preparing for the agregation national exam, level M2) and ENSAI (complexity and calculabilty, level L3), thanks to this mission.

The last three years (2016-19)¶

I was doing my PhD. Please read this page to learn more! I now hold a PhD in telecommunications. My PhD thesis is here and the slides used for my defense are there.

In 2015-16¶

I was a research intern in the BIG/LIB team at EPFL (Lausanne, Switzerland), from April to August 2016, under the supervision of Julien Fageot and Michael Unser. Check out the git repository for my internship (my Master thesis is finished) !
I obtained the MVA master program (at ENS de Cachan, now ENS de Paris-Saclay), in applied Maths, mainly in machine learning and numerical optimization. Cf. my documents written for the MVA, and 6 projects: PCS, PGM, RL / GML, Kernel, Brain Imaging, Neuro-Sciences. I ranked first for the MVA master in 2015-16, with 13 courses valided and the final grade of 18.43 / 20 (« summa cum laude »).
I was also teaching in Maths. and in Computer Science in a prep” school for national competitive exams for French Engineering Schools (« Grandes Écoles »), at « Lycée Lakanal » in Sceaux (near Paris).

Studies and past jobs¶

From mid-July 2014 to mid-May 2015, I lived and worked in India, on the campus of the new Mahindra École Centrale (a new Engineering College born from a partnership between the (Indian) Mahindra group and (French) École Centrale de Paris). I was the first French faculty to work there full-time, and I have been involved as a teaching assistant, in charge of mathematics (MA101 and MA102) tutorials, and in charge of the Computer Science CS101 course for the second semester!
In 2013/2014, I prepared and obtained the (French) agregation of Mathematics exam (national competitive exam for « Prep Schools » teacher recruitment, with a major in Maths and a minor in Computer Science). I have been ranked 23rd, for 275 available positions, for 795 candidates allowed to pass the oral exam (second step) in June and July 2014, and almost 1200 persons registered in October 2013. I also did the second year of my Master of Science in Fondamental Mathematics (major) and Computer Science (minor), with a speciality on teaching. A list of useful references (and other ressources) for this exam is here.
In 2012/2013, I did the first year of the MPRI (Master of Science specialized in theoretical research in Computer Science, in Paris) and also the first year of the Master of Science in fondamental mathematics of ÉNS Cachan (again both magna cum laude).
From 2011/2012, I studied at ÉNS Cachan, and in July 2012, I completed two Bachelors of Science, one in Mathematics and one in Computer Science, both magna cum laude.
During two years, 2009/2010 and 2010/2011, I studied in Marseille, at Lycée Thiers, first in MPSI 2 and after in MP*1.
