Leading both the Query Understanding and the Ranking teams. Managing 4 senior scientists. I also served as a Scientific Director for the Search team, responsible for ensuring a proper scientific methodology across different teams.* I researched, designed, and implemented the Query Performance Prediction system that powers the new Qwant search engine.

Qwant is the privacy perserving search engine that doesn't know anything about its users.Applied IR and NLP research for improving Qwant's ranking quality and evaluation. Full-remote.* I standardised offline ranking evaluation methods and datasets using both implicit and explicit judgments* I pushed a new version of Qwant's ranking model to production.

Providing tailored machine learning solutions to clients.* Natural Language Understanding of text and audio messages. Sequence labelling with distant supervision (no human labels) through a contextual Bi-LSTM for tagging entities, followed by a fusion of ranked lists for item retrieval.* Time-series consumption forecasting of a water distribution network.

* Researching and analysing web logs data inorder to describe how people visit and consume online open access academic documents.* Analysis of web server logs to understand how people interact and consume the content of an open access platform for academic content.* Implemented predictive models of dwell time, session-based document embeddings, taxonomy of.

* Unsupervised identification of salient and relevant audio parts from multi-lingual news reports, with no other information than the audio signal.* Annotation interface for judging and ranking the relevance of the extracted audio parts.* Supervised learning to maximize informativeness.* Publication at CICLing.

Collaboration with Jian-Yun Nie and Josiane Mothe. Working on Learning to Rank approaches for identifying the best retrieval system configurations.* Reducing the combinatorial problem of finding the best parameters of an ad-hoc document retrieval system by learning to rank grids of parameter configurations according to their full retrieval performance.*.

Research scientist position as part of the Search & Relevance team, working on improving the performance of a businesses and points-of-interest search engine.* Zero-shot classification of out-of-vocabulary multi-word terms according to the labels of an in-house taxonomy.* Prototype for vertical search.

Worked as a postdoc on the EU funded SMART FP7 project, aiming at improving information access within smart cities.* Development of probabilistic and Learning to Rank models for recommending Points of Interest (POI).* Writing of project deliverables.* Publications in CIKM'14, CIKM'15, IIiX'14, ICWSM'15, CORIA'15.* Participated in TREC'14, CLEF/RepLab'14.

Working on my PhD thesis, trying to take contextual information and user-oriented resources into account to improve the accuracy and the effectiveness of search systems* Multi-word terms extraction methods for improved query models.* Unsupervised query-biased topic modelling (Latent Dirichlet Allocation), hyper-parameter tuning algorithms (published paper.

I worked as a member of the "Free Software" team, and I developped free web applications dedicated to collaborative work (http://gpl.univ-avignon.fr). These applications had to be generic, easy to use and easy to install because other french universities are currently using them. I first developped an application which allows to create groups of people in.

My work was related to the European research project LUNA (http://www.ist-luna.eu), an automatic speech recognition system which was specialized in hostel reservation. I improved a software which displays finite-state automata with and half-developed another which processes annotated corpus into graphic dependencies. These two softwares can directly.
