General Electric Lighting, Cleveland, OH, Principal Engineer, 1987 - 2016

  • Conceived product designs, and led concept development, of several of GE Lighting's flagship LED lamp product lines.
  • Novel optical, thermal, system, and aesthetic breakthroughs resulted in tens's of millions in sales.
  • Managed programs and teams across every major legacy lamp technology within GE Lighting including automotive; High Intensity Discharge (MH and CMH); fluorescent; halogen thin films; and incandescent.


  • PAR LED replacement lamp exceeded the performance and aesthetic of halogen lamps, enabled by a low-glare optic with a smooth beam and unique lighting appearance achieved world wide.
  • The first Energy Star qualified A-line LED replacement lamp (Energy Smart brand), enabled by breakthrough optical and thermal designs, also resulting in the world's first LED replacement lamp to achieve 100 LPW.
  • GE's first BR30 LED replacement lamp.
  • The first color-preference-enhanced LED replacement lamps (reveal%uFFFF brand) A19 and BR30 lamps, and luminaires (reveal%uFFFF TriGain%u2122 brand), enabled by my co-development of a new state-of-the-art color preference metric, the Lighting Preference Index (LPI-worldwide).
  • LED display lighting exceeded all visual and performance attributes of the incumbent Low-watt Ceramic Metal Halide lamps (reveal%uFFFFWhiter White brand) combining optical brightening for whiter whites with reveal%uFFFF technology for enhanced colors (first worldwide).
  • GE's first lighting to promote circadian health (Align%u2122 and C-sleep brands); primary author of "GE Lighting - Lighting and Sleep."
  • Established and led a lamp development team, and a production and sales operation.
  • Led the growth of that engineering and production operation increased staff resulting in $2 million sales.
  • Developed advanced, innovative new lamp products through the invention, engineering, and production phases, in the areas of metal-halide lamps, halogen lamps, and thin film technology.
  • Provided innovative leadership in the technical training of GE employees, in corporate volunteer activities, and in the recruiting and hiring of new employees.

GTE Sylvania Lighting, Danvers, MA, Research Physicist, 1985 - 1987

  • Developed laser-based diagnostics for arc discharge and halogen lamps, including laser absorption, laser-induced fluorescence, and Rayleigh scattering measurements of gas and plasma parameters.
  • Conceived and initiated the development of several novel concepts for new lamp products.

Sandia National Laboratories, Albuquerque, NM, Member of Technical Staff, 1981 - 1985

  • Developed and implemented several novel, advanced, laser-based diagnostics on terawatt pulsed-power accelerator experiments in the Ion Beam Nuclear Fusion program, with nanosecond resolution, using Ruby, Nd:YAG, and HeNe lasers.

Princeton University, Princeton, NJ, Ph.D. Research Associate, 1977 - 1980

  • Independently discovered and investigated a new plasma instability in a Q-machine plasma. Published all the essential linear and non-linear, experimental and theoretical properties of the instability as it related to plasma transport in Tokamak nuclear fusion reactors.
