I’m astronomer at observatoire de la Côte d’Azur and involved in optical interferometry since many decades. Many colleagues call me the ‘homme orchestre’ and this picture illustrates clearly what this means! This one has been taken during our impressive developments of a prototype of an hypertelescope (an optical Arecibo interferometer) in a valley of the Southern Alps but this is another story… (http://lise.oca.eu, http://hypertelescope.org)

I have been working with Antoine Labeyrie from the very beginning and developed with him the GI2T (boules) interferometer on Plateau de Calern. Then I developed as PI the GI2T/REGAIN project and I have been coPI of the VLTI/AMBER instrument.

In 2005 we decided to stop the activities in Calern and I developed the VEGA instrument installed on the Mount Wilson (News). After more than 500 nights of observations and 50 papers, VEGA has been stopped in december 2020 to permit the preparatory work for the SPICA visible instrument and near infrared (Project Overview)
