Laure Saint-Raymond joins Laboratoire Alexandre Grothendieck in September 2021
Thomas Gauthier joins LMO in Septembre 2021
My research is concerned with holomorphic and arithmetic dynamical systems. More precisely, I study interactions between these two fields of research, using tools from pluripotential theory, complex analytic geometry, arithmetic geometry, combinatorics and measure theory.
I defended my PhD Thesis in the Université Toulouse 3 Paul Sabatier under the direction of François Berteloot. I then was an ATER (temporary assistant professor) at the Université Toulouse 2 le Mirail. I then was Maître de Conférence at the Université de Picardie Jules Verne in amiens from 2012 to 2018, period during which I visited the Institute of Mathematical Studies at Stony Brook University, NY for a semester. I then was Professeur Monge at Ecole Polytechnique from 2018 to 2021. Since September 2021, I am pleased to be a Professor at the Laboratoire de Mathématiques d’Orsay, at the Université Paris-Sacaly.
Muriel Boulakia joins LMO in Septembre 2021
I am working in the field of Partial Differential Equations. My works focus on the mathematical analysis of fluid-structure interaction problems and on the analysis and the numerical methods for inverse problems. Part of these works is motivated by the field of biomedical applications, in particular cardiac electrophysiology and hemodynamics.
After a PhD thesis at UVSQ under the supervision of Jean-Pierre Puel and a postdoc at Inria Paris in the REO project-team with Jean-Frédéric Gerbeau, I have joined the LJLL at Sorbonne Université as assistant professor in 2006. Since 2021, I am professor in the mathematics laboratory of the University of Versailles St-Quentin.
Bruno Duchesne joins LMO in Septembre 2021
Geometric group theory is my research field. It aims at revealing relations between some algebraic structures and geometry. One specific point of this field, and which is really exciting, in my opinion, is the manipulation of mathematical objects coming from many different areas of mathematics. Functional analysis, probabilities or algebraic geometry appear along proofs.
My Ph.D. thesis was defended in 2011 and written between Geneva and Lyon. Thanks to a grant from the Swiss National Foundation, I spent one year in Jerusalem as a postdoc. Then, I have been assistant professor at Élie Cartan Institute in Nancy. Since 2021, I’m professor in the department of mathematics at Orsay.
Claude Viterbo joins LMO in Septembre 2021
My main interest is in symplectic topology in a very wide sense, going from fundamental aspects, like Floer cohomology and Fukaya category all the way through applications, ranging from Hamiltonian dynamics and Hamilton-Jacobi equations, real algebraic geometry, functions of several complex variables, or microlocal theory of sheaves. I am always fascinated by the depth and number of these applications.
I started my career as Chargé de recherches at Ceremade (Paris-Dauphine) from 1985 to 1991, then was a Professor at Orsay (1991-2001), at Ecole polytechnique (2011-2021), Ecole normale supérieure (2011-2021) and I am finally back at Orsay where I am delighted to reconnect with old acquaintances and also meet many new colleagues.
Jérôme Casse joins LMO in September 2021
My research interests are at the frontier of Probability, Discrete Mathematics and Statistical Physics. I am particularly interested in quasi-reversible interacting particle systems, in probabilistic cellular automata and in iterated Brownian motion ad libitum.
I did my PhD thesis in LaBRI (computer science department of University of Bordeaux, France) from 2012 to 2015 under the supervision of Jean-François Marckert. Then, during one year (from 2015 to 2016), I was a research and teaching assistant in Mines Nancy and in the probability and statistics team of IECL (mathematics department of Nancy, France). After that, during three years (from 2016 to 2019), I was a postdoctoral researcher in the mathematics department of NYU Shanghai (New York University of Shanghai, Chinese branch of NYU) in China. Then, I was a CNRS postdoctoral researcher in the probability and statistics team of LMO (mathematics department of University Paris-Saclay) during two years (from 2019 to 2021) financed by the ANR MAlIn (Interacting Random Walks). Since 2021, I am assistant professor in the same team and I teach math in the IUT of Sceaux.
Maud Delattre joins MaIAGE in January 2021
I am interested in parametric estimation in models with Markovian dynamics and latent variables (mixed effects models, diffusion models, ...). I study the theoretical behavior of estimators and I develop algorithms (EM, stochastic EM, ...). I am also working on questions of selection of variables in these models. Most of my research is motivated by applications in pharmacology, epidemiology or even plant biology. I developed most of my research within the UMR AgroParisTech / INRAE "Mathematics and Applied Computing" where I was a maître de conférences from 2012 to 2020. I am now a research fellow in the INRAE lab Mathématiques Informatique Appliquée, du Génome à l'Environnement (MaIAGE) in Jouy-en-Josas.
Jean-Marie Mirebeau joins Centre Borelli in October 2020
My research is devoted to the design of numerical schemes for the resolution of partial differential equations, often related to optimal control and optimal transport, and to their applications. My specialty is the resolution of strongly anisotropic equations, which locally favor certain directions of space, by addressing the resulting numerical difficulties using computational geometry tools. These works are motivated by applications to mathematical image processing, seismic tomography, and trajectory planning or detection.
I defended a PhD thesis in 2010, under the supervision of Albert Cohen at Pierre and Marie Curie University, on the subjet of approximation theory with anisotropic triangulations. In 2011, I joined Paris-Dauphine University as a CNRS researcher, and started a collaboration with Laurent Cohen on mathematical methods for medical imaging. I joined the Orsay mathematics department at University Paris-Saclay in 2015, then the Borelli center at ENS Paris-Saclay in 2020 as research director.
Ester Mariucci joins LMV in October 2020
My research interests lie at the frontier of mathematical statistics and applied probability, with a special focus on nonparametric statistics (both from a frequentist and a Bayesian perspective) for stochastic processes, especially for jump processes.
I am also interested in the comparison of statistical models in the Le Cam sense and I love to work on distances between continuous or discrete observations of stochastic processes.
After defending my Ph.D. thesis in Grenoble in 2015 under the supervision of Sana Louhichi and Pierre Étoré on asymptotic equivalences for nonparametric models, I joined Aad van der Vaart's research group in Leiden, where I started working on Bayesian nonparametric statistics. I then moved to Markus Reiß’s research group in Berlin where I focused on (minimax frequentist) statistics for jump processes, a topic I continued to work on during my stay in Magdeburg. In 2018-2019 I was a visiting professor at the University of Potsdam and since 2020 I am a professor in the mathematics laboratory (LMV) of the University of Versailles St-Quentin-en-Yvelines.
Pierre-Guy Plamondon joins LMV in Septembre 2020
In my research, I work on links between algebraic structures, combinatorics and geometry. On the algebraic side, my main interest lies in the representation theory of associative algebras and in abelian, exact and triangulated categories. I am interested in applications of these structures to the geometry of polytopes such as the associahedron, to the combinatorics of triangulations and dissections of surfaces, and to the theory of cluster algebras.
After obtaining a degree in mathematics in Sherbrooke (Quebec, Canada), I have defended my thesis at Université Paris-Diderot 2011, followed by a one-year postdoc in the LMNO at Université de Caen. In 2012, I have joined the LMO at Université Paris-Sud/Université Paris-Saclay as a lecturer. I am currently a professor in the LMV at Université de Versailles Saint-Quentin, since September of 2020.
Guillaume Kon-Kam-King joins MaIAGE in January 2020
Je travaille à l’interface entre la statistique bayésienne non-paramétrique et la modélisation de données biologiques, notamment les données “omiques” et les données de bio-essais. Mes contributions scientifiques concernent les données censurées, la modélisation hiérarchique bayésienne, l’analyse de survie, l’estimation bayésienne non-paramétrique de densité, les processus bayésiens non paramétriques dépendents et l’inférence sur des processus de diffusion dans le cadre des modèles de Markov cachés.
J’ai étudié la physique à l’ENS Cachan et à l’Ecole Polytechnique Fédérale de Lausanne, où j’ai travaillé dans le laboratoire de Giuseppe Foffi en collaboration avec Davide Fiocco et Hans-Joerg Limbach, ainsi que dans le groupe de Félix Naef en collaboration avec Jonathan Bieler.
En 2012, j’ai rejoint le groupe de Vittoria Colizza où j’ai collaboré avec Michele Tizzoni et Paolo Bajardi. J’ai ensuite rejoint le Laboratoire de Biométrie et de Biologie Evolutive à Lyon pour un doctorat sous la supervision de Sandrine Charles et Marie-Laure Delignette-Muller. En 2015, j’ai débuté un post-doctorat à Turin dans le groupe d’Igor Prünster et de Matteo Ruggiero. Depuis 2020, je suis chargé de recherche dans l’unité Mathématiques et Informatique Appliquées du Génome à l’Environnement (MaIAGE) d’INRAE à Jouy-en-Josas.
