Stéphane completed his Ph.D. studies at the University of Galway (Ireland) working on an Information Retrieval engine for Linked Data and became deeply interested in that field. He then transitioned to working for Siren, a spin-off of that research endeavor. From that point on, he worked on Federate, an Elasticsearch plugin for computing joins between inverted indices, and was responsible for maintaining and developing various parts, e.g., from the query planner to the interactions with Lucene like with the query cache.
