Career Highlights

My years of experience has given me the opportunity to:

  • Reduce welding-costs a factor of 4 through introduction of automated welding-processes for joining stainless steel in thicknesses from 0.049” to 5.0”, and transferred the technology to two commercial fabricators.
  • Lead a team in the development of friction-stir welding of thick-walled Al alloy pressure vessels
  • Resolve stainless steel and structural steel weld-cracking problems in conjunction with private industry without loss in manufacturing cost or schedule.
  • Develop ultrasonic inspection equipment for non-destructive examination of thick steel  welds and transferred the technology to two commercial fabricating shops.
  • Serve as an “expert witness” in cases involving failures of trucks and pressure-vessels.
  • Use fracture-mechanics codes to determine the lives of large structures, lifting fixtures, and cranes.
  • Manage design, construction, and operation of a cryogenic mechanical-testing facility and an aqueous corrosion  test-facility.
  • Teach materials science and processing at University of California-Berkeley, San Jose State University, University of Maryland, and George Washington University.
  • Be an advisory editor for “Cryogenics”, a scientific journal.
  • Chair, Structural Materials section of the International Cryogenic Materials Conference Journals.

I have developed extensive projects for:

  • Lawrence Livermore National Laboratory
  • Department of Energy,
  • U.S. Steel Corporation
  • United Aircraft Corporation
  • Republic Aviation Corporation
  • Grumman Aerospace Corporation
  • I.T.E.R. Fusion Reactor projects
