Assistant Professor -- Maître de Conférences Laboratoire Jean Kuntzmann (LJK) , Université Grenoble Alpes Full CV : Français -- Google Scholar Profile Contact : firstname.lastname |a|_ univ-grenoble-alpes.fr or imag.fr News June 2017 : The conference CAp 2017 (Conférence sur l'apprentissage automatique -- 19th annual meeting of the francophone Machine Learning community) held in Grenoble June 28-30 was a great success. It was co-organized by the AMA team at LIG and our team DAO at LJK, the general chair was M.-R. Amini. Mar. 2017 : Our course project on Distributed Optimization for Big Data was granted a development funding from IDEX Grenoble Alpes. The Goal is to raise our Convex and Distributed Optimization to the next level with state of the art technologies (Python/Jupyter, Spark, Docker) and to a wider audience. Nov. 2016 : I gave a tutorial talk about Gossip algorithms at the Machine Learning seminar SMILE in Paris. Slides: Part I -- Gossip algorithms , Part II -- Gossip and Optimization. (The animations may not work with all PDF viewers, they should do fine with Adobe's) Sept. 2016 : Jerome Malick and I taught a concentrated (6h per day during 3 days) Refresher course on Numerical Matrix Analysis and Optimization for students of different Master at Grenoble (MSIAM, MoSig, MSCIT). Details can be found in the introduction presentation. Apr. 2016 : The website of our new team DAO ``Optimization and Learning for Data Sciences'' is online! Sept. 2015 : I joined the Laboratoire Jean Kuntzmann (LJK) , Université Grenoble Alpes as an Assistant Professor (Maitre de Conférences) Feb. 2015 : I joined the Université Catholique de Louvain as a Post-Doc, in the ICTEAM Institute working mainly with Julien Hendrickx Mar. 2014 : I have designed a small script to visualize the contraction properties of alpha-averaged operators (necessits the support of HTML5 by your browser). This is still a beta version, email me if you have remarks/comments/...! Jan. 2014 : I joined the Alcatel-Lucent Chair on Flexible Radio as a Post-Doc with funding from the ERC More (Advanced Mathematical Tools for Complex Network Engineering) . working mainly with Romain Couillet and Merouane Debbah Dec. 2013 : I defended my Ph.D. thesis entitled Distributed Estimation and Optimization in Asynchronous Networks and prepared at Telecom ParisTech .
