Skills and Experience
Production & Test Engineering -- in my positions with TRW, Pyramid Technology, and Echelon Corp.
• Technical writing -- within MIL-Q-9858 and ISO 9001 environments, I wrote test plans, policies, procedures,
work instructions, process deviations and engineering changing orders
• Existing products -- serviced and supported the product lines such as monitoring quality and reliability, investi-
gating and fixing problems, and implemented changes to product design or parts lists or approved vendor lists
as required
• Improvement -- re-designed subsystems for improved reliability and cost reduction
• New products -- devised production plans and test plans for computer peripheral boards and control networking
modules
• Equipment -- specified and purchased the instruments and tools necessary to implement the test plans
• Custom apparatus -- designed and fabricated special mechanical and electronic fixtures and tools; wrote cus-
tom test software
• Vendor management -- managed multiple contract assembly houses by monitoring quality via incoming in-
spections and directly working with vendors to maintain required level of quality
• Manufacturing technologies -- supported production of products utilizing multilayer double-sided surface
mount, ceramic substrate, and chip-on-board
• Product reliability -- tracked field failures, investigated root causes, communicated with customers to resolve
their usability and reliability issues
• Training -- trained assembler personnel and technicians on the production lines and receiving inspection
• Team meetings -- participated in product design team meetings with peers and participated in project readiness
meetings with the CEO and VP’s
• In-house quality -- established and managed a equipment calibration program and a production ESD program;
handled the product agency audits (UL, CSA, TUV, VDE)
Research -- in my position with the University of Oregon
• Theoretical and numerical study -- participated in creation of models for carbon dioxide capture from coal
power plant flue gases by cryogenic and oxygen enriched techniques
• Apparatus -- designed and fabricated custom electronic instrumentation and mechanical equipment which I uti-
lized in the research lab (including analog, digital and embedded micro-controllers)
• Data collection -- designed and assembled computers, data acquisition subsystems and sensors; executed the
experiments to collect the raw data
• Data reduction and analysis -- designed methods, and wrote custom software, to pull information and conclu-
sions from the raw data
• Technical writing -- wrote grant progress reports, white papers and peer reviewed published scientific papers
• Training -- trained undergraduate and graduate students to run the experiments
Product design -- in my position with TRW
• analog -- designed and prototyped a power supply board for an early laptop computer
• digital -- designed and prototyped a controller board for an encrypting facsimile device
Programming language proficiency -- C, Fortran, Perl, Common Lisp, LabView, Maple, Octave (matlab clone), as-

2. sembly, and various specialized scripting languages
Test equipment proficiency -- DSLR cameras, machine vision cameras, digital and analog oscilloscopes, spectrum
analyzers, lock-in amplifiers, motor controllers, voltmeters, signal generators, universal counters, cryogenic tem-
perature controllers, DAQ cards, GPIB interfaces, various sensors
Software tool proficiency -- MS/Office, Openoffice, Maple, Photoshop, Gimp, Inkscape
