My postal, digital and physical addresses are:

Université Paris Diderot - Paris 7
Bâtiment Sophie Germain
UFR d'Informatique
8 Place Aurélie Nemours
75013 Paris, FRANCE

Now if you want to meet me in real life, the most simple thing to do is to send me an email and we surely be able to find a good place to meet, since I have no room.

The old procedure was :

To see me, the first step is to find the building named “Sophie Germain”. It is located Avenue de France, 75013 Paris. Be careful, somebody already reported that there is also such a valid address in Adélie land, so if the ground looks too icy get back and try again. It is in-between “Porte de France / Bibliothèque François Mitterrand — RER” (take a breath) tramway stop, “Bibliothèque François Mitterrand” RER-C—line 14 subway station, and final stops of bus lines #325, #62 and #89. Beware, as the building is secured from floor #3 to the top (french people are are just like C arrays and start counting from 0), so you may need to call me before, wait until a gentleman let you enter or ask the guards. Whatever, you will find me on the 4th floor, room #447. If you make a mistake, don’t worry the building is full of humans enhanced with functional interactive vocal devices.
