The LMM is organizing the last two weeks of May 2024 (from May 21 to May 31, 2024) an important event in probability, statistics and risk for its 30th anniversary. The first week (of 4 days) will include two “statistics and probabilities” days (May 21-22) and two “risk” days (May 23-24). The second week (May 27-31) will be devoted to two summer schools (ANRs DREAMeS and EFFI). These two weeks will above all be an opportunity for CHL researchers and international researchers invited to this occasion to discuss their research themes.
