I teach 3 online courses at present: Jazz Piano, The Art and Science of Creativity (including songwriting) and Gambling (Craps). At present these courses have over over 350 students and counting.

Federal Aviation Administration (FAA)

Engineer responsible for safety review and design certification of large passenger transport aircraft. Sole Propulsion specialist charged with maintaining safety of the Boeing 737NG fleet consisting of 3300 aircraft, equaling a total passenger load of approximately 495000 souls. Duties included safety oversight, risk assessment, initiating and drafting Airworthiness Directives (ADs) (Code of Federal Regulations -14 CFR) to address safety problems, compliance issues, adjudicating public and industry comments, designating Alternative Methods of Compliance to existent Airworthiness Directives, maintenance and production oversight, certifying new and type design changes for aircraft, as well as examination and decision making in regard to industry certification test plans implementing design changes. Worked closely with members of European Aviation Safety Agency (EASA) to facilitate adoption of ADs in Europe and world-wide. Participated as a flight test engineer during aircraft system testing.

Tethers Unlimited

Tethers Unlimited is an aerospace company which specialized in the development of commercial spaceflight and planetary sensor systems. Primary role was that of design engineer/prototype build test engineer. Design/build experience included work on magnetoplasmadynamic (MPD) thrusters to optimize plasma flow to boost thrust in electric propulsion engines (NASA SBIR). Created test systems to quantify and validate friction and lift assist in the momentum-exchange/electrodynamic reboost (MXER) satellite tether system, used to deploy, boost or deorbit satellites without the use of propellant. Devised multiple sensor deployers, including a ballistic deployment system funded by NASA in order to deliver small sensor packages to remote/hazardous locations on other planets, a parachute mounted expanding sensor perimeter launcher, as well as quick acting pneumatic ball detents and NASA standard initiator powered gas generator deployment systems. Designed and built a sensor launch platform that released no external combustion gases, and produced safety report prior to offsite explosive testing. Other designs included climbing/rescue systems (pneumatic launcher/expanding grapnel). Design consult and machining of cube-satellite parts (presently in orbit).

Russell Lindbergh Aerospace

Primary work was on an automated control, data gathering, and scale-able rocket engine test stand initially capable of firing a 1000-lbf thrust restartable Liquid Oxygen/Kerosene engine incorporating a proprietary carbon-fiber regenerative cooling jacket. Contributions consisted of complete design and machining of a stainless steel pintle injector incorporating film cooling, cryogenic Teflon seals and high temperature Viton seals for the combustion chamber. Injector prototype was built utilizing a CNC lathe and 3-axis mill. Conceptualized, built and incorporated a propane/NOX ignition system into the injector, with integral thermocouple for positive ignition system feedback. Test stand accomplishments included design/build of the fuel flow and pressurization/vent systems for both the Kerosene and LOX sides. Modified existing aluminum tanks for storing LOX and kerosene into stack-able, expandable configurations. Designed and machined custom tank fittings and plumbing. Designed and built pneumatic control valve actuators. Routed control air from a computer controlled valve manifold. Designed and machined manifolds for a prototype cryogenic fuel level measuring system based on differential pressure within fuel tanks. Assisted in LOX cleaning of tanks and lines.

University Of Washington

Responsible for teaching design and machining to engineering students. Instrument work consisted of prototype design consultation and was the sole fabrication machinist for the Department of Mechanical Engineering. Duties also included instrument shop management, maintenance and guidance/supervision of students in all shop areas. Machined parts ranging in use from an Antarctic telescope mount to a prototype cryogenic molecular scanner.
