Education: Master of Science in Engineering, with research
emphasis in Materials Science, ASU, 1997Related Coursework:

AuditsAccomplishments:
Performed Source Approval evaluation and Substantiation of power
shaft P/N 2-141-340-03 forHoneywell electron beam weld vendor
Middleton Aerospace. Used metallography to determineconformance to
AMS2680. Implemented a shorter pump down cycle to improve
productivity by50%. Reduced weld porosity by reducing weld traverse
speed, which allows more time forgases to escape the molten pool,
reducing scrap by 65%.
Performed Special Process audit of Bennett Heat Treat, a
Honeywell supplier of brazed diffuserassemblies. The brazed
diffuser assembly had been exposed to excessive time and
temperaturein the braze cycle, resulting in braze erosion. To
mitigate braze erosion, I implemented a shorterand cooler braze
cycle and used tooling with reduced thermal mass. Productivity
increased90%.
Resolved braze cracking issue at Ace Precision in the Combustor
Liner Assembly, P/N 2-131-110-63. Prior to this design change, the
part cracked in the solidified braze filler metal due tothermal
stresses. The pie pan concept was implemented which allowed a more
robust designwith more mass to reduce thermal stress. The crack
issue was resolved, the Combustor LinerAssembly was substantiated ,
and went into production saving Honeywell approximately$150,000
annually.
Provided Honeywell-Mora in the Czech Republic with the technical
expertise to qualify foreffusion (laser drilling on the fly) hole
drilling of combustors to enhance cooling and increase
service life of combustors. Used metallography to determine hole
size, alignment, and remeltlayer thickness to insure conformance to
PNCP52574. This allowed us to reduce manufacturingcosts without
compromising part integrity. Annual savings of $325,000 were
achieved.
Professional Experience:Principal Materials Engineer, Orbital
Sciences Corp, Chandler AZ, 2009
Performed audits of orbital welds (GTAW) used in Attitude
Control System of ground basedmissile and launch vehicles.
Performed assessments of launch vehicle components to identifyand
mitigate corrosion by intergranular attack, stress corrosion
cracking, and galvanic couples.Developed course and test materials
for Weld Certification of 28 design engineers, given11/18/09.Senior
Materials Engineer, Honeywell, Phoenix AZ, 1998-2009
Performed process approval and substantiation of welded and
brazed components (diffusers,nozzles, combustors, curl assemblies)
for Honeywell-Mora (Czech Republic) and Honeywell-
Chihuahua. Processes transferred include brazing, laser hole
drilling, electro-dischargemachining, orbital welding, automated
and manual GTAW, RSW, electron beam, laser, andinertia
welding.Metallurgical Engineer, IMC Magnetics, Tempe AZ,
1993-1998
Copper furnace brazing per AMS2670, GTAW, and heat treat of
magnetic Fe materials invacuum.Supervisor of the Metallurgical Lab,
Chromalloy (Jet Services West), El Cajon CA, 1990-1992.
Prepare and evaluate metallurgical specimens. Pratt and Whitney
LCS reporting to MarkCrevier. Created parameters for brazing,
welding, EDM, ECM, RSEW, RSW, heat treat, andplasma spray.
