Accelerator Engineer
Design, test and prototype devices for an electron beam accelerator. Activities include: designing and performing experiments at room and cryogenic temperatures (LN2 77K & LHe 2K); performing mechanical and electrical assembly of experimental apparatus; interfacing experimental assemblies with computer-aided data acquisition; performing data analysis; documenting designs using CAD software; writing papers on results of experiments; developing procedures for experiments and assembly. In addition to my test responsibilities I also, work on facilities for supporting production that included Ultra Pure Water (UPW), Cleanroom facilities (I served as cleanroom technical lead), I produced the software for monitoring particle counts for both the UPW and cleanroom using Igor Pro (the cleanroom particle and usage display won an award for the innovative use of Igor from Wavemetrics the maker of Igor) and I was responsible for all maintenance and upgrades to the most critical piece of production equipment the High Pressure Rinse (HPR). My work on the HPR included replacing the pump with a pump that is much cleaner (cleanliness is critical in the production of cavities), designing and having made a simple alignment system for the wand, rebuilding the controls, daily monitoring of the particle counts and the particle counter status and making upgrades to the cabinet. I also, was consulted nationally and internationally for my expertise on cryogenic seals (seal patent pending), water quality, particle counting and High Pressure Rinsing. Return to Experience.

Simulator System Engineer
Designed hardware for Boeing 757 and High Speed Research (HSR) flight simulators. Created signal lists, cabling diagrams and system diagrams. Directed Technicians in the construction of the hardware and cabling and set work priorities. Interfaced with contractors, suppliers, researchers and internal organizations to ensure that all the requirements were met and that problems were resolved in a timely manner. Used CAD and electrical drawing software to produce drawings of the hardware. Wrote software for the flight simulators and provided a resource base for the software group for dealing with the hardware designed. Return to Experience.

Adjunct Faculty
Teach skills to workers being displaced. Courses taught Include Mechanical Diagnosis and Repair Methods, Non-destructive Testing, Vibration Analysis, Basic Lubrication, Basic Bearings, Shaft Alignment, Pneumatics and Hydraulics.

Mechanical Engineer/Programmer
Write computer software for modeling oil spills and the response to clean up oil spills. Dealt with ABS, USCG and commercial standards as they applied to oil spills. Provide a modeling knowledge base and expertise. Wrote software that resulted in a savings of $1,000,000.00. See resume sections on Design and Analysis, Administration & Management, Project Management and Computer Skills. Return to Experience.

Mechanical Engineer
Designed the plumbing and heating, ventilation and air conditioning systems for commercial and government buildings that complied with building codes and ADA requirements. Reviewed shop drawings, interfaced with contractors, prepared specifications and cost estimates. Designs covered systems using DX coils, cooling towers, closed circuit coolers, boilers, furnaces and piping systems for both new work and the renovation of existing buildings. See Project List for a complete list of projects. Return to Experience.

Principal Test Engineer
Responsible for developing and managing the Thermal Structures Laboratory and the connected machine shop. Performed experimental research and testing in the laboratory. Wrote test and operational procedures. Authored or co-authored papers on the results of the tests. Handled data acquisition, data reduction and data analysis. Developed test procedures and designed test set-ups and apparatus. Interfaced with machine shop on the construction of test apparatus. Coordinated the purchase, installation, maintenance and use of new and existing equipment. Managed and coordinated the activities of project engineers and the technicians. Scheduled and planned equipment use and laboratory activities using MS Project. Maintained knowledge base of laboratory projects and research center capabilities. Designed and oversaw the installation of new systems and system upgrades. Developed hydraulic, cooling water and electrical plans to support the laboratory. Interfaced with the contractors performing the work and handled trouble shooting. Prepared cost estimates for new facilities and reviewed cost estimates prepared by other engineers. Provided reports to support environmental compliance. Return to Experience.

Project Aerospace Engineer (Test)
Responsible for creating and managing the Thermal Structures Laboratory and the connected machine shop and for reactivating the Actively Cooled Test Stand for structures research. Performed testing, handled data acquisition, data reduction and data analysis, wrote test and operational procedures. Authored or co-authored papers on the results of the tests. Designed test set-ups and apparatus. Coordinated the purchase, installation, maintenance and use of new and existing equipment. Managed and coordinated the activities of the technicians.
