Welcome to IRIF IRIF, the Research Institute on the Foundations of Computer Science, is a research laboratory of CNRS and université Paris-Diderot, also hosting two INRIA project-teams. The research conducted at IRIF is based on the study and understanding of the foundations of all computer science, in order to provide innovative solutions to the current and future challenges of digital sciences. IRIF hosts about 200 people. Six of its members have been distinguished by the European Research Council (ERC), three are members of the Institut Universitaire de France IUF), and two are members of the Academia Europæa.

Topics include sequent calculus, differential logic and probabilistic computation. 19.4.2019 Iordanis Kerenidis (IRIF) explains what we can expect from Quantum Computing in this interview of the CNRS journal. 16.4.2019 Ali Charara, director of INS2I at CNRS, visits IRIF on the morning of April 24th. The research conducted at IRIF will be presented as well as 6 specific scientific talks. The visit will be followed by a light buffet lunch. 15.3.2019 From March 20th to May 22nd, Uri Zwick (Univ. of Tel Aviv) will give a series of 7 courses related to his FSMP Chaire of Excellence on the topic of Games on Graphs and Linear Programming Abstractions each Wednesday 2:15pm - 4:15pm at IRIF, room 3052. 19.4.2019 Université Paris Diderot has opened several teaching assistant positions (ATER) in Computer Science on the research topics of IRIF. Deadline to apply : May 6, 2019. 5.4.2019 Penny Haxell from University of Waterloo (Canada), a world wide expert in extremal combinatorics and graph theory, is visiting IRIF March 28th to May 2nd. Extremal combinatorics Extremal combinatorics studies how large or how small a collection of finite objects can be, if it has to satisfy certain restrictions. For instance, in an n-element set, what is the largest number of subsets of which none contains any other? The question is answered by Sperner's theorem, which gave rise to much of extremal set theory. Another kind of example: How many people can we invite to a party where among each three people there are two who know each other and two who don't know each other? Ramsey theory shows that at most five persons can attend such a party. 17.3.2019 The Paris Region PhD2 program will grant 30 PhD projects on Digital Sciences and with an industrial partner. IRIF is an eligible hosting lab. Call for application is open until May, 15th 2019. 1.2.2019 IRIF has the great pleasure to welcome Uri Zwick, professor at the Blavantik School of Computer Sience (University of Tel-Aviv), who is visiting for four months. His stay is financed by an FSMP chair. Uri is an expert in algorithms, data structures and games.
