I have completed my Ph.D. in mathematics and computer science under the supervision of Professors Srecko Brlek, from Université du Québec à Montréal, in Canada, and Laurent Vuillon, from Université de Savoie, in France.

Since August 1st, 2014, I'm a regular assistant-professor at Université du Québec à Montréal, in Canada.




As it says on the home web page, Sage is a free open-source mathematics software system licensed under the GLP. Its main mission is to create a viable free open source alternative to Magma, Maple, Mathematica and Matlab. Below is an animation created by Sébastien Labbé and Xavier Provençal using Sage:

During Summer 2008, Arnaud Bergeron, Amy Glen, Sébastien Labbé and Franco Saliola have created the initial version of the Words library which has been merged in Sage. The next year, Sébastien and Franco redesigned and improved the architecture of this library in order to simplify many of its aspects. Note that it is possible to deal with infinite words and to extract many important information on words. On the other hand, there is still room for improvement and anyone interested in the matter is invited to contribute.

So far, I have been involved both as an author and as a reviewer in tickets about graph theory and combinatorics on words.

  • On September 1st, 2010, I was one of the three organizers of Sage Day 25.5;
  • Together with Sébastien Labbé and Franco Saliola, I was an organizer of LaCIM Sage Fridays for the Falls 2010 and Winter 2011 semesters.
