• Seminars given by internationally renowned researchers
• Technological conferences, to follow the progress of laboratory practices in connection with new equipments or new concepts
• "Trans-science" conferences for all staff to feed our curiosity outside our research areas.

For the general public:

• Events such as the national science festival, hosting patient associations or participating in open days of APHP hospitals,
