Mathematical software

For my research, I often use the free* mathematical software systems PARI/GP and Sage. I regularly contribute to Sage by implementing new features, fixing bugs and improving existing code. I have also made a few small contributions to PARI/GP.

* Free as in "free speech", not only as in "free beer"; see the GNU project.

Sage Days, 22–26 July 2013

Together with Maarten Derickx and Michiel Kosters, I organised an edition of the Sage Days, titled Algorithms in Arithmetic Geometry, in the Lorentz Center in Leiden, 22–26 July 2013. For further information, see the workshop webpage and
