Profile Summary

Career has focused on space-based optical systems for defense, astronomy, weather and Earth resources. Have also participated in significant programs involving ground-based optical laboratory test equipment and several commercial industrial and medical products.

Have specialized in optical components and optical assemblies for NASA and DoD applications throughout my career. Have experience with lightweighted beryllium, glass, glass-ceramic, and other materials. Have also led a design team on the complete opto-mechanical design for a CCD camera and beryllium telescope used in a defense application. Managed strategic, tactical, civil space and other types of programs as a senior program manager. Have experience with design for ultra-high, long-term stability of mirrors and space-based structures as well as contamination controls associated with space optics.

Program manager for design and development of multiple lens designs used in the Clementine mission that mapped the moon. Managed program for geosynchronous weather satellite telescope and several programs for optical systems used in space-based, free-space laser communication. Deputy program manager for polishing of lightweighted beryllium mirrors for the Webb Space Telescope (JWST). Experienced with overhead persistent infrared reconnaissance optical systems.

Managed design and development programs for factory optical test equipment for a stellar sensor in an astro-inertial guidance system. Managed design and development of Hubble Stimulus, laboratory test equipment used to test the Wide-Field Planetary Camera 2 which corrected the aberrations of the Hubble Space Telescope.

Managed commercial programs that developed a high precision projection lens used in the development of the Digital Light Processor chip (DLP) as well as a first-of-its-kind X-ray-to-visible scintillator integrated with a Schmit Cassegrain Telescope containing a high-resolution CCD for digital mammography.
