Knowledge-Driven Engineering Executive with success in developing cross-functional engineering teams to reliably deliver working designs before major capital investments are made.

  • A proponent of data-driven design: applying known laws of physics and engineering to product development; utilizing analysis, modeling and simulation in formative design followed with direct-testing at the sub-system level to prequalify functional design; resulting in more reliable, well-characterized products with predictable success: an increased certainty of performance, robustness, and schedule-of-delivery. 

  • A proponent of active client engagement — understanding and delivering to my clients' core values. 

  • A master and lifelong student of technologies in diverse areas such as solid mechanics, micro-fluidics, thermal management, transdermal sensing, in-vitro technologies, packaging for environmental protection to computed tomography and x-ray source development, and more.

  • Expert at integrating knowledge-driven design; developing and managing multi-disciplinary teams and processes; designing/planning/prioritizing/standardizing/budgeting/managing engineering organizations at the resource, team, departmental and infrastructural levels.



  • Triple Ring Technologies.  Built a productive, respected mechanical engineering team from 0 to 10+ FTE with variable staffing of 2 to 6 consultants and contractors. Led the design of a novel, robust, x-ray system C-arm.

  • MAP Pharmaceuticals. Finalized Metered Dose Inhaler (MDI) based breath actuated inhaler design for clinical trials. Established fundamental forces using simple fixtures and tests and corrected fundamental design flaws related to MDI valve actuation.

  • Aradigm. Managed SBIR Phase II project —“Pulmoshield”(for measles vaccination in the third world). Conceived of and developed a successful, all-mechanical, version of Aradigm’s AERx. This included a new architecture for the AERx electromechanical extrusion engine. Utilized thorough analysis of architectures and a staged program of simple prototypes and careful testing.

  • Abbott Laboratories. Led radical redesign of IV pump to reduce parts count and cost.



  • Disciplined (sub-functional) building-block approach to problem-solving and design.

  • Thorough understanding of phased medical device development and design controls. Ability to identify key design elements and areas requiring focused effort for speedy development. 

  • Expert mechanical engineer with hands-on experience in: robotics and mechanism design – motor, human, and stored energy powered; plastic, metal injection molded and powdered metal part design; managing stresses and deflections by appropriate deployment of materials; machined and sheet metal component design; classical analytical methods – kinematics, stress/strain, etc.; mechanical CAD and Finite Element Analysis (FEA); conductive and convective heat transfer; percutaneous, pulmonary, and transdermal drug delivery.

  • Flexible, adaptable approach to problem-solving has enabled me to make mission-critical contributions in designs from handheld devices (using high-volume manufacturing methods) to large capital equipment (using weldments and other appropriate low-volume manufacturing methods). 

  • Adept with laboratory and assembly tooling and fixtures; good laboratory and data analysis skills, including DOE; and hands-on-capable computer skills with team-relevant applications: PTC Creo and Windchill, Solidworks, Mathcad, Matlab, Mechanica, Comsol.  MS Excel, Word, Powerpoint, Project, and Visio.
