Professional Experience
Walleye Technologies, Inc. Somerville, MA 2005 to present
As Chief Technologist, I invented a (patent pending) Millimeter-Wave imaging system offering diffraction limited resolution at ~1% of the cost of a conventional MMW system. The technology consists of a holographic scanning antenna operating in a confocal geometry. The camera can be built for under $50 and is currently being configured brought to market as an inspection tool. (4 patents pending)
Resonetics, Inc. Nashua, NH 2002 - 2005
Optical Engineer
Resonetics manufactures excimer laser micro-machining systems. I designed, implemented and sustained approximately 20 different optical configurations ranging from R+D evaluations to million piece production runs. A central theme was to increase photon collection and transmission efficiency to increase throughput and lower costs. A new type of optical beam delivery method was invented that homogenized a long-line beam and improved machining speed 300%. 1 patent issued, 2 patents pending.
TwinPhoton/ Minigram 2001 - 2002
Key contributor in two start-up efforts.
TwinPhoton, Inc., a BU Photonics Center spin off, developed quantum optical metrology and compensation technology to eliminate polarization mode dispersion in long haul fiber links. 1 patent
Minigram, Inc. developed wireless PDA technology providing low cost internet. 4 patents pending.
