The IHP hosts or sponsors many events designed for the advancement of science through the interaction between scientists:
- Quarterly thematic programs, organized by a small team within the IHP: the Centre Emile Borel (CEB). They are coordinated by invited organizers, selected by the Scientific Steering Committee of the IHP on the basis of criteria of scientific excellence and relevance, as well as balance between themes. These programs bring together French and foreign invited scientists, who are provided with offices and housing assistance, thus providing an opportunity for the French community to enrich its expertise in new subjects. The CEB encourages the activities related to physics within mathematical programs and vice-versa, with the aim of increasing the interchange between these disciplines.
- A doctoral program, offering high-level complementary courses on various topics, taught by French and foreign researchers. These courses can take place at the IHP, in other institutes such as the CIRM or Les Houches, or in French universities, under the auspices of IHP wich provides logistical and financial support. This program starts in 2011 after a trial period in 2010.
- intensive short-term collaborations, gathering a group of researchers around a common project (program: RIP = "Research In Paris").
- Hosted activities, sometimes encouraged, supported and promoted by the IHP.
