John M. Hughes is an embedded systems engineer with over 30 years of experience in electronics, embedded systems and software, aerospace systems, and scientific applications programming. He was responsible for the surface imaging software on the Phoenix Mars Lander, and has worked on digital engine control systems for commercial and military aircraft, automated test systems, radio telescope data acquisition, and realtime adaptive optics controls for astronomy. Hughes has been using Python for many years in a variety of applications, including the software for a multiwavelength laser interferometer system for verifying the alignment of telescope mirror segments on the James Webb Space Telescope. He is currently using Python for imaging systems simulation and analysis at the University of Arizona.
