I have collected here, for convenience, the links to the pages I created for various conferences that I (co)-organized since 2008. All those which were held in Zürich were supported by FIM.

Random matrices, L-functions and primes	This was co-organized in 2008 with A. Nikeghbali (UZH).
Exponential sums over finite fields and applications	This was co-organized in 2010 with N. Katz (Princeton), Ph. Michel (EPF Lausanne) and R. Pink (ETH).
Group actions in number theory	This was a special semester co-organized with Ph. Michel (EPF Lausanne) during the Spring Semester 2011 at the Centre Interfacultaire Bernoulli at EPFL.
Hot Topics workshop: thin groups and super-strong approximation	This was co-organized in February 2012 with E. Breuillard (Paris-Sud), J. Ellenberg (Wisconsin), A. Gamburd (CUNY) and H. Oh (Brown).
The 2012 Number Theory Days	This was the 9th edition of the EPFL-ETHZ Number Theory Days, co-organized with Ph. Michel.
Equidistribution in number theory and dynamics	This was co-organized, in March 2013, with M. Einsiedler (ETH), E. Lindenstrauss (Hebrew University) and Michel (EPF Lausanne).
Twenty five years of number theory seminar	This was co-organized in 2013 with G. Wüstholz (ETH).
Analytic number theory, in honor of É. Fouvry's 60th birthday	This was co-organized in 2013 with R. de la Bretèche (Paris), Ph. Michel (EPFL) ,and J. Rivat (Marseille).
