SUMMARY
Accomplished Principal Engineer / Senior Project Engineer in the medical device, semiconductor,
automation, and aerospace industries for over 15 years. Led engineering teams to deliver a number of
successfully released innovative products, product features and automation processes. Creative and well
versed in various forms of technical analysis, having over 20 granted patents in many different fields
covering a number of released medical device, aerospace, and automation products.
NozTek LLC (Startup), Elyria, OH 2009 – Present
Manager/Owner
Started a manufacturing company with innovative products for the high speed automated packaging market
• Invented and filed a US patent application on a novel 90 degree nozzle assembly for molten
thermoplastic adhesives
Designed, analyzed, built, and successfully brought through verification tests two different product
•
lines of high temperature thermoplastic nozzle assemblies
Executing high volume pilot production of the product line at this time to verify product cost targets
•
and product performance from the high volume production process at customer beta sites
Generated initial business plan including the marketing & sales plan, competitor analysis, financial
•
plan, product development plan, intellectual property plan, and manufacturing/quality plan
Refining a new product design for field test in order to file a patent application by year end
•
ASYMTEK (Nordson Corp.), Carlsbad, CA 2006 – 2009
Principal Engineer
Led a team of up to 5 engineers to develop new semiconductor manufacturing technologies, products, and
automation processes.
• Invented the dot weight statistical control algorithm being used in the system control software on all
Asymtek semiconductor under-fill platforms (work cells). This algorithm was then adapted for flux
dispensing systems and is currently being used in the industry. The algorithm is a trade secret and
was not patented intentionally.
• Led a team in developing new isothermal dispenser designs that were the only performance
enhancements in the newly released DJ9500 (under-fill), and DJ2200 (flux) dispensers for
semiconductor packaging. (1 patent pending)
• Developed a new circuit board conformal coating method for higher product throughput, and better
coating edge definition. (1 patent pending)
• Led a team in developing a new ultra light weight high pressure fluid pump for mounting on the Z
head of a 3 axis robot. The pump was designed and used to handle caustic materials and pressurize
them safely up 1600 psig.
• Designed, organized and led many successful large scale Design Of Experiments (DOE) and process
variability tests.

ETHICON ENDO-SURGERY (JOHNSON & JOHNSON), Cincinnati, OH 2002 – 2006
Principal Engineer
Led a team of up to 4 engineers to develop, design, build and test implantable electric gastric banding
devices, and surgical instruments.
• Invented a disposable 5 mm articulating laparoscopic surgical dissector. Released as the Disposable
Goldfinger. (US20070185519)
• Lead technical engineer in developing electrically powered gastric banding bariatric implants.
Focused on developing an inductive (TET) implant power system, implant packaging compatible
with TET, implantable sensors, electromechanical actuators compatible with MRI imaging, and an
ultra-low frequency implant telemetry link. (US7191007 (pat.), US7481763, US7390294,
US7374565, US7351240, US7351198)
NORDSON CORPORATION, Westlake, OH 1994 - 2001
Senior Project Engineer
Led a team of up to 5 engineers in developing new high speed automated liquid coating technologies
• Led a team in inventing, and developing a piezoelectric high speed (>1kHz) valve technology for
dispensing a wide range of viscous materials. (US6157115)
• Led a team in inventing, and developing a high speed, low voltage solenoid valve technology for
dispensing filled coating materials. This technology was released as the MEG™ gun product line,
which saved the container division of Nordson (US5791531)
• Invented the electromagnetic portion of a new electric hot melt valve that became the E350™ series
of hot melt guns. (US5875922)
• Created and taught a well received corporate wide course on solenoid valve design
ETHICON ENDO-SURGERY (JOHNSON & JOHNSON), Cincinnati, OH 1992 – 1994
Technology Assessment Manager
Performed the technical evaluation of possible company and IP acquisitions for Ethicon. Worked within a
cross functional acquisition team. Generated and evaluated new medical device concepts.
• Successfully led the technical portion of the acquisition of the optical trocar patent that allowed
Ethicon to develop, and sell optical trocars (This has turned into a >$40 million/year product)
• Lead engineer in inventing and developing a new family of articulating 5 mm laparoscopic
instruments. (US5374277, US5330502)
• Invented and developed new electrosurgical methods and trocar devices (US5674184, US5540684,
US5445142)
•
PARKER HANNIFIN, Irvine, CA 1983 - 1992
Senior Project Engineer
Led a team of up to 8 engineers to develop new aerospace and automation technologies.
• Led a large engineering team in inventing and developing a multi-channel fiber-optic position
sensing system for use in flight controls. This system was successfully tested on a F18 aircraft at
NASA Dryden. (US5541405, US5693935)
• Invented and led a team in developing the Phototrak™ absolute encoding system released for
production by the Compumotor division. (US5258931, US5095632, US4954931, US4892416)
• Developed and taught a highly successful corporate wide course on developing, and programming
computer automated testing systems.
