Peter Wizinowich, Chief of Technical Development

About Peter

Peter Wizinowich has been with the W. M. Keck Observatory `ohana since 1991. During this time he has played a lead role in the installation and alignment of the telescope optics, the design and implementation of the Keck adaptive optics systems and Keck Interferometer, the development of engineers and postdocs, and the management of the observatory’s technical projects. Peter actively collaborates with astronomers using Keck AO (Adaptive Optics) and groups developing adaptive optics systems around the world.  He has been Principal Investigator for fourteen Federal and Foundation funded projects totaling $42M and co-Principal Investigator for another $10M of funding.
