Hello, since Nov. 2018, I am on an “advanced research position” at Inria, in the WIDE team.
“Maybe, not content to be alienated by observation, maybe does the object deceive us? Maybe it invented original answers, and not only the ones we ask for? May not be does it not want to be analyzed and observed at all and taking this for a challenge (which is true), does it respond with another challenge? […] the object analyzed today triumphs everywhere, by its object position, over the subject of analysis.” (Jean Baudrillard, Fatal Strategies.)
My main current research activity is trying to disprove that quote, by studying black-box algorithms in the context of recommender systems, neural-network models, or decision-making algorithms in general. I am also interested in algorithms for the distribution of machine learning (deep networks, GANs).
I was a senior research scientist at Technicolor R&I (2009-2018), where I worked on scalable storage, processing and machine learning for data analytics and monitoring of home devices. I own a PhD on distributed systems from University of Rennes 1, and a background on peer-to-peer systems, and graph mining/algorithms. My Ph.D. thesis was financed by Orange Labs (where I stayed btw 2004-2007). I obtained my habilitation (HDR) on November 2016 from University of Rennes 1. I am the president and sysadmin of the gozdata association, that provides the gozmail service, built from free software.

As my main participation to scientific events, I was co-chair of Middleware 2018 industry track, in Rennes, and AlgoTel 2019 program co-chair. Co-organizing WOS with INRIA and Interdigital (ex Technicolor), a workshop on storage, cloud processing and data analytics, in every year Rennes: WOS archive.
I have co-authored 8 granted patents, and around 39 pending demands.
I have contributed to produce a document on “Transparency and audit of algorithms” regarding the GAFAM, for the French DGE. In general, I am broadly interested in the impact of technology on society.
