Sylvain CetreSylvain Cetre, Adaptive Optics Software Engineer, Durham University & Wakea Consulting

Sylvain Cetre started his career in astronomy in 2004 after a degree in applied mathematics at the Grenoble Laboratory. After developing a tool to research calibrators for interferometric observation at the Jean Marie Mariotti Center in Grenoble, he quickly joined, in 2006, the ALPAO founders team by writing the deformable mirror drivers and the base of Alpao Core Engine. After 5 years helping the company to grow to the world leading company for deformable mirrors, he joined the W.M. Keck observatory in 2012 to participate in a decade of AO developments at the twin 10 meters telescopes in Hawaii. During the next 10 years, he helped rebuild the laser guide star system on both telescopes, developed the new near infrared tip tilt sensor on Keck I and the infrared pyramid wavefront sensor of the Keck Planet Imager and Characterizer on Keck II (KPIC). He then took the technical lead of the Real Time Computer upgrade for both the telescope and the software lead of the Keck All-sky Precision laser tomography Adaptive optics system on Keck I (KAPA). In parallel, he was working with University of California Santa Cruz (UCSC) to help with AO developments in the Laboratory of Adaptive Optics (LAO). He now works at Durham University, building the Real Time Computer for HARMONI which will be a first generation instrument for the ESO European extremely large telescope. In parallel, he funded his own consulting company in Adaptive Optics Wakea Consulting to continue collaboration with Keck and UCSC.

Olivier GuyonOlivier Guyon, Astronomer, Subaru Telescope and the University of Arizona

Olivier Guyon is an astronomer at the Subaru Telescope and the University of Arizona. He is an expert in exoplanet imaging techniques: coronagraphy, adaptive optics, spectroscopy and interferometry. He leads the Subaru Coronagraphic Extreme-AO (SCExAO) instrument, where new approaches in extreme adaptive and high contrast imaging are prototyped and validated. Olivier develops coronagraph systems for future space-based exoplanet imaging missions and ground-based extremely large telescopes.




Stefan StröbeleStefan Ströbele, Systems Engineer, European Southern Observatory (ESO)

Stefan Ströbele joined the European Southern Observatory (ESO) in 1998 to develop a method for the alignment of the coplanarity of image-sensors in mosaiced CCD cameras.

He lead the systems engineering of the SINFONI Adaptive optics module over its full live cycle from preliminary design, system integration, commissioning the operation and maintenance up to its decommissioning.  As system engineer of GALACSI an Wavefront Sensor Module he contributed to the development of the ESOs Adaptive Optics Facility. As project engineer he leads ESOs DM development activities.
