Damien Gratadour is the P.I. of the COMPASS project. He is an Associate Professor at Université Paris Diderot and research scientist at LESIA, Observatoire de Paris since September 2008. Dr. Gratadour holds a master degree in theoretical physics from Université Paris Diderot and a PhD in Observational Astronomy from the same university (2005). In the past, Dr. Gratadour has been responsible for the last stages of commissioning of the LGS upgrade to the Altair AO system on the Gemini North Telescope in Hawaii (2006) and assumed for almost 2 years, as an AO scientist, the responsibility of Instrument Scientist for GeMS, the Gemini MCAO System, a 15M US$ facility featuring 6 LGS and 3 DMs, actively participating to the various acceptance tests and integration of its sub-systems and first stages of technical tests of the full instrument and most notably the DSP-based RTC. Since 2008, at Observatoire de Paris, Dr. Gratadour is concentrating on high performance numerical techniques for astronomy for modeling, signal processing and instrumentation and on the development of observational programs, with AO equipped large ground based telescopes, for the study of star formation in merging galaxies.
Arnaud Sevin is a software engineer at LESIA since 2006. He is the project manager of the COMPASS project. He is also the coordinator of the ground based instrumentation team of the LESIA software engineering group. Mr Sevin holds two master degrees in engineering and management of information systems and digital imaging (2002 & 2005). His past experience includes the development and integration of data acquisition systems for several instruments (FLUOR, PERSEE, CAMICAz) as well as the integration and tests of the SPHERE XAO system RTC recently installed on the VLT.
Denis Perret is an electronics engineer at LESIA since 2004. He holds a master degree in electronics and signal processing including majors in FPGA programming for high speed acquisition systems and co-processing, real time computer programming and image and signal treatment and analysis. He has developed, designed and realized several analog electronics, for the servo-control of tip-tilt mirrors (on SPHERE and CANARY), the data acquisitioon on near-IR camera (CAMICAz) and the control of a coil and magnet based deformable mirror (MAOUSS). He has also an extensive experience in FPGA programming, especially for detector clocking (CAMICAz) and high speed communication, including the design of a 10 GbE interface to PCIe support the GigeVision protocol.
Julien Brulé is a IT systems administrator at LESIA since 2006. He holds a master degree in cooperative and distributed systems from Université Paris – Sud computer science laboratory. He is responsible for the deployment strategies and the long term maintenance of the COMPASS platform. At LESIA, as an IT systems administrator, he is notably responsible for the deployment of distributed / parallel computing solutions (MPI, RPC, RMI, threads POSIX) and the deployment and maintenance of GPGPU clusters. He has also been involved in the performance validation of high-speed interconnect through NVIDIA’s GPUdirect protocol in the context of the COMPASS project and is now leading innovative research on the use of the Jetson ARM+GPU system from NVIDIA for embedded applications in the ground based instrumentation team of the LESIA software engineering group.
Mathieu Puech is an astronomer at GEPI, Paris Observatory. He got his PhD in 2006 at GEPI, and after a couple of years at ESO-Garching in 2007-08, he went back at GEPI where he got a permanent position in 2010. His scientific interests are related to galaxy formation and
evolution. He was involved in the scientific exploitation of the first multi-integral field spectrograph FLAMES-GIRAFFE at VLT and a co-I of the IMAGES survey, which was the first 3D survey of distant galaxies. He is also strongly involved in instrument studies. In the past, he
was actively involved in the E-ELT Design Reference Mission as a member of the E-ELT Science Office at ESO, and afterwards as a member of the EAGLE and OPTIMOS-EVE consortia during the ESO E-ELT Phase A Instrument studies. He is now co-Project Scientist of MOSAIC, a new MOS concept proposed to ESO for the E-ELT. He is the scientific coordinator of the COMPASS project.
