I am currently Maitre de Conférences (Associate Professor) at the University of Toulouse 1 Capitole and I am a member of the IRIT lab (SIG team). I am also an external member of the LI of the University of Tours where I received my PhD in 2013.

My research topic is mainly focused on the field of database analysis, in particular: recommender and personalization systems, similarity measures, log mining, datawarehouses, OLAP. I had also the opportunity to work on use cases of data mining algorithms (especially frequent patterns) applied for cultural heritage and logs of car configurations. I am also interested in the hadoop systems.

A resume is available here (in french) and my list of publications here.
