Emmanuel Pietriga
Chargé de Recherche - CR1, interim leader of INRIA team In Situ.
Full-time research scientist working for INRIA Saclay - Île-de-France.
I previously worked for: the World Wide Web Consortium (W3C) and Decentralized Information Group at MIT's Computer Science and Artificial Intelligence laboratory (formerly LCS) as a post-doc; Xerox Research Centre Europe and INRIA Rhône-Alpes where I prepared my PhD in Computer Science; and Nuxeo as a software engineer.
I am working on novel interaction techniques, including multi-scale/zoomable user interfaces in structured graphics environments; wall-sized displays; visualization and editing of structured data, such as that found on the Semantic Web; visual language environments; applications in the domains of astronomy, bioinformatics, GIS and more.
