The meeting will be held at Institut Henri Poincaré, 11 rue Pierre et Marie Curie, in the 5th district of Paris. This is really at the heart of the Latin Quarter. It is easy to reach from the Luxembourg RER (express regional train) station, on the line B. This station is well connected to Charles de Gaulle and Orly airports, and also to the stations Gare du Nord and Gare de Lyon (take RER line A and change at Chatelet). There are many small restaurants in the vicinity of the meeting place available for lunch.
