Publications

Any software on this page is distributed “as is” under the GNU general public license. TL;DR: use at will, let me know if you want to modify the source code, don’t sue me if your computer explodes :-)

Copyrights of the published versions of the papers below belong to the publishers. Essentially, this means that publishing houses get to overcharge academic institutions for access to their employees’ research, even though all the work was carried out, reviewed and edited with no cost to the publishers. If you want to learn more about this ridiculous system, this 2017 long read by the Guardian has a ton of information on the topic.

If you’re wondering about the numbering scheme, “W” is for working/submitted papers, “J” is for journals, “C” for international conference proceedings, “S” for software, and “D” for dissertations. For the most part, publications appear in (roughly) reverse chronological order, but you can also navigate the various tags to see a list of publications by year, venue, or topic. You can also visit my author pages on arXiv, ResearchGate and HAL.

For admin use: author ordering is discipline-specific and often depends on whether there is a junior researcher involved.
