I'm a researcher in algebraic combinatorics and also an assistant professor in Computer Science in Universite Paris-Sud Orsay. PyCon 2015 is going to be my second PyCon. I'm a big fan and contributor to the open-source python-written mathematical software Sage which I have been using since the beginning of my thesis in 2010. I've attended many Sage days and try to share my love of programming and Python with other mathematicians. And now I'm here to share my love of math and computer exploration combinatorics with other pythonistas!
