My current research is related to data visualization, human computer interaction, visual data mining, 3D data and interfaces, data mining with proximity graphs, clustering, optimization using meta heuristics (often related to visual and interactive approaches). My favorites applications domains are Medicine and Biology, Digital Humanities. 

This project is funded by the ANR. We developp methods to detect Autism Spectrum Disorder (ASD) in children from eye tracking data. The machine learning problem we have is to automatically design features (with various ML algorithms and representations). Then we want to propose visual analytics to mine those results, so as to explain the classifiers/representations performances, and to compare them to expert-based features. 

The PhD of Hélène Walle is centered on this contribution (with co-supervision of my colleagues Pascal Makris, Yassine Mofid, Frédéric Rayar). This project is performed in collaboration with the iBrain Lab (project leader). 

With the PhD of Ben Crulis (co-supervised with my colleague Cyrl De Runz), we study two properties of CNNs: one is to reduce their size, so as facilitate their use on mobile devices (for blind people). The other topic is the incremental learning of images, with the aim of letting a person add new objects to recognize. 

I'm also studying other topics, like HCI for visually impaired people, including virtual reality in a game environment. 

In this project funded by the ANR, we study the automatic generation of dashboards in a Business Intelligence context where users are novices (in BI, in dataviz). Our work  package consists in designing a user assistant that will suggest complete dashboard to users. We will use our previous experience with Vizassist.  The overall project is described here. 

The PhD of Praveen Soni is ongoing, with the co-supervision of my colleagues Fatma Bouali and Cyril De Runz.

This project is funded by the AND (France) and DFG (Germany) and consists in studying specific sculptures and their origins. Our contribution will be the scanning of sculptures and the detection of tools traces (as a future way to determine the origin of the artwork). 

This year we have developed several interactive devices to extend the work of Laurence Dréano into the digital world. Among other things: an interactive lighting organ, several holograms, an Augmented Reality app, other interactive sculptures. See what the local press says (here also, or here). Those devices were presented during an exhibition. We also prepared an exhibition "Rêves de lumières" at The Chateau Royal de Blois (see the photographs below).
