Denis Mourard is a former fellow of the Ecole Polytechnique, Paris. He graduated from the University of Nice Sophia Antipolis in 1990 (team of Pr. Antoine Labeyrie) on the development and the scientific exploitation of the long baseline interferometry at visible wavelengths. His carreer started at Calern Observatory in the Southern Alps where he developed the GI2T interferometer and permitted for the first time an in-depth analysis of the rotating disk around a famous Be star. This has contributed to the opening and expansion of this research field which is now a mature technique used in the largest observatories in the World.

In 2005 he started a strong collaboration with the CHARA interferometer at Mount Wilson Observatory and installed a visible spectro-interferometer remotely controlled and producing unique spectral and angular resolution for the study of fundamental parameters of stars and planets, and their circumstellar environments. In parallel he continues to pursue his long-term goal shared with Antoine Labeyrie for the development of ambitious high spatial resolution imagers based on the hypertelescope principle.
In 2012 he has been nominated as Deputy director for Astronomy and Astrophysics at CNRS,National Institute for Sciences of the Universe.
