Interest and Expertise
- Design for
Manufacture and Assembly: Training, product analysis, conceptual design.
- Mechanical
Design and Analysis:
Creative design; probabilistic
methods, optimization, simulation; stress, dynamic, vibration, and heat transfer
analysis; expert witness
- Design Methods
and Systems: Training and application of design methods such as DFA, FMEA,

Design
for Manufacture Training
- Develop and
present customized workshops on Design for Manufacture and Assembly and related
topics to manufacturing companies, both large and small.
- More than 75
Design for Manufacture and Assembly (DFM/A) workshops have been presented
to more than 40 different companies such as Square D, Whirlpool, Chrysler,
Lockheed, Navistar, Siemens, Bell and Howell, and Northrop-Grumman.
- A variety of
specialized design methodology workshops have been developed for clients such
as Square D Company, General Electric, and Corning.
- A unique feature
of many of these workshops is the use of a "hands-on, brains-on"
approach that provides ample opportunity for participants to internalize the
concepts and to apply them to selected client products and sub-assemblies.
Expert
Witness
Expert
witness in a variety of patent infringement, trade secret, product liability,
and other legal cases. Advised U.S. Magistrate Judge in lawsuit involving complex
mechanical equipment.
