• Associated Researcher in Applied Statistics
    Jan 26, 2014 to Apr 30, 2014


    Three partners, l’Institut IRAMAT - CRPAA in Bordeaux, the Laboratoire de mathématiques Jean Leray in Nantes and the Laboratoire Geosciences in Rennes, involved in Chronomodel project (ANR 2011-2015), developed an original software, named chronomodel, which is dedicated to the chronological modeling with a Bayesian statistical approach. This software provides support for the development of chronological scenarios from a large number of data involving time, using models more or less complex (via the stratigraphy, the phasing, the correlation data, the calibration functions,…).

    Job Description

    The associated researcher should develop, with the chronomodel software, Bayesian statistical methods and tools for data processing involving time in the Archeology, Archaeometry and Earth Sciences areas.
    In particular, the associated researcher will be responsible to:
    • Develop new tools for statistical Bayesian chronological modeling;
    • Integrate additional modules to the chronomodel software;
    • Develop an interface between the R software and chronomodel software;
    • Conduct statistical studies asked by laboratories or local government;
    • Assist the users of chronomodel software.
    During the appointment, the associated researcher could have the opportunity to participate in other projects of Lebesgue Center on applied Statistics.

    The successful candidate will be placed under the scientific responsibility of Anne Philippe, Professor in Mathematics at the Laboratoire de mathématique Jean Leray.


    • PhD in Mathematics in the area of Statistics;
    • Skills in Bayesian statistics;
    • Computer programming skills (C + + / R);
    • Interest in archeology;
    • Fluency in English.

    Conditions of employment:

    The appointment is fixed term for 12 months, from September 1st 2014 to August 31st 2015, with a 3-month trial period. It is subject to the French public law, and renewable thereafter for up to another year. The successful candidate will be appointed to the “Ingénieur de recherche” Grade position, according to qualifications and experience. The monthly salary will be between 1 900€ and 2 200€ net. The associated researcher will be recruited by the University of Nantes on behalf of Lebesgue Center. His workplace is the Laboratoire de mathématiques Jean Leray, whose rules will be applicable.

    Information and application

    The applicant should complete the online form and join the following documents:
    • A detailed curriculum vitae;
    • A copy of the doctoral degree, the report of PhD, and the PhD defense;
    • A letter of motivation;
    • One or two letters of recommendation.

    The position is expected to start: September 1st 2014.
    The deadline for application is: April 30th 2014.

  • Spring school - Classical and p-adic Hodge theories
    May 12, 2014 to May 23, 2014

    Rennes, from May 12th to May 23rd, 2014
    Contact: C. Mourougane
    Scientific board: X. Caruso, F. Charles, M. Gros, C. Mourougane

    We organize a spring school on complex and p-adic aspects of the Hodge theory with a view towards deformation theory.

    The first week is devoted to constructions of complex and p-adic Hodge theories, for a single smooth variety or for a smooth family of smooth varieties. In the complex setting, construction of moduli spaces thanks to Torelli type theorems will be the main target. In the p-adic setting, the first aim will be the constructions of cohomological tools and the second aim the statement and the proof in a special case of comparison theorems between p-adic cohomologies.

    Hodge theories of deformations with singular fibers will be the topic of the second week. In the complex setting, one leading theme will be the use of Hodge theory in the description of properties of moduli spaces like hyperbolicity. Similarly, some properties of étale cohomologies and more surprisingly complex cohomologies will be derived from p-adic Hodge theory.

    Each course will be given in English and divided into three lectures of 90 minutes.

  • Conference - Effective moduli spaces and applications to cryptography
    Jun 10, 2014 to Jun 13, 2014

    Rennes, from June 10th to June 13th, 2014

    Moduli spaces are parameter spaces for mathematical objects equipped (or not) with extra structures. The cases of spaces classifying curves and abelian varieties have been widely studied in their theoretical aspects which entailed dramatic advances in arithmetic geometry. Nonetheless, more effective aspects for instance related to rationality questions or depending on the characteristic of the base field are less well understood. Certain field of applications require tools and algorithms to manipulate efficiently these moduli spaces. This is case for instance of public key cryptography since certain cryptosystems have public parameters which naturally live inside certain moduli spaces.

    This conference aims at gathering specialists of moduli spaces of curves and abelian varieties, algorithmic and cryptography so as to explore the deep link and the possible interactions between theoretical and practical aspects of moduli spaces.

Practical information for the meeting WS3

How to come to Rennes

If you arrive in Paris either by plane or train, the simplest is to use the french high-speed train (TGV) to go to Rennes (2h15' from Montparnasse station, 3h from the Airport station).

For those landing at Charles-de-Gaulle airport, you may also use a connecting flight to Rennes.

How to reach your accomodation place

To go to the Adagio hotel from the railway station: take the subway (direction J.F. Kennedy) from station "Gares" to station "Saint-Anne", and then walk on "rue d'Antrain" street (see the map below) from "Place Saint-Anne" to the hotel.

To go to Résidence universitaire from the railway station: take bus n°1 (direction Cesson-Sévigné) from stop "Gares" to stop "Mirabeau". Then walk down to builiding D (see the map below).

How to come to the conference place

The conference will take place in amphitheater N of ESIR building (ESIR=école supérieure d'ingénieurs de Rennes) on Beaulieu Campus (campus map).

From the Adagio hotel: take bus n°31 (direction "Beaulieu Chimie") from the stop "Hôtel Dieu" to the stop "Beaulieu Chimie" . You then have to walk to ESIR building (see the map below).

From Résidence universitaire: you can walk to ESIR building (see the map below).

From the railway station: take the subway (direction J.F. Kennedy) and stop at "Republique". Then take bus n°4 (direction Beaulieu Atalante) and stop at "Beaulieu Chimie". You then have to walk to ESIR building (see the map below).

Timetables, PDF maps of the bus lines are available on the Star website (only in french sorry).
