The overarching goal of Chalifoux's group is to enable next-generation space telescopes by developing new methods of precision fabrication, mounting, and alignment of lightweight optics, especially mirrors. The group uses both experimental and analytical/numerical techniques to understand and improve on the behavior of these processes.Show Less
