About

Julien Girard is an instrumentation physicist/astronomer currently working as Operations Staff Astronomer at ESO spending his time between Santiago de Chile and Paranal Observatory (VLT telescopes). He joined ESO in 2009 as Adaptive Optics (AO) specialist to support the NaCo instrument as well as current/future AO facilities. He obtained a master's degree in Instrumentation Physics from the University of Utah after building a calibration system for the HiRes ultra-high-energy cosmic ray experiment. Back to the French Alps, he completed another master's in Astrophysics in Grenoble and tested integrated optics recombiners for long baseline interferometry. Appealed by high angular resolution instrumentation, he defended a PhD in 2005 at CRAL/Observatoire de Lyon for his contribution to the polychromatic laser guide star project ELPOA. Julien worked three years in Mexico City as a postdoctoral fellow at UNAM and as a professor at IPN. He helped developing a curvature based AO system in the laboratory and was involved in the robotization of telescopes for optical to infrared synoptic surveys and gamma ray bursts followups. His astronomical research interests are broad, from faint (brown dwarfs, planets) companion search to active galacti nuclei multi-wavelength characterization. Julien also enjoys participating to public outreach activities.
