CURRICULUM VITAE

Daniel Sage is a specialist of open-source imaging software for various modalities of microscopy, including super-resolution, deconvolution, image restoration, tracking, segmentation, and image quantification. He is involved in numerous image-processing and image-analysis projects dealing with life cell imaging. He is also engaged in the development of methods for computer-assisted teaching.

Daniel Sage was born in Annecy, France. After his university degree, he did a Ph.D. in image processing at the TIRF laboratory, Institut National Polytechnique de Grenoble (INPG). From 1989 to 1998, he was a Consulting Engineer developing vision systems for quality control, then Head of the Industrial Vision Department of Attexor S.A. During his career, he has developed some vision systems oriented to the quality control in the industrial sector. In 1998, he joined the Biomedical Imaging Group (BIG) at Ecole Polytechnique Fédérale de Lausanne (EPFL) as responsible of software development. He is in charge of both the coordination of software development and of setting down the computing infrastructure of the laboratory.
