CNRS Researcher at Laboratoire d’Informatique de Grenoble (LIG)
Head of the MRIM research team
Worked until October 2016 on integrating language models on graphs for photograph description, in collaboration with Globe VIP
Participated in multimedia indexing and retrieval evaluation campaigns: NTCIR Lifelogging, CLEF Image Annotation
Co-managed (with Lorraine Goeuriot) a CLEF Tweet Contextualization Lab task on evaluating tweet indexing/retrieval quality from festivals

Background
Information Retrieval Researcher
Works on modeling and experimenting with indexing and retrieval of text and visual data
Currently focuses on continuous evaluation of Web search engines in the Kodicare project
Also works on explainable video retrieval
Collaborates with Schneider Electric on indexing and retrieval of normative documents
Previously focused on theoretical IR models (e.g., using Jensen-Shannon divergences) and hypotheses like the Document-Document Matching Constraint
Investigates whether such constraints apply to continuous representations (e.g., LDA, LSA, deep learning)
