About

PROFESSIONAL PROFILE
* Senior-level engineering analysis experience performing structural, response/vibration, dynamics, fracture and fatigue, and pressure vessel blast and fragmentation analysis in the aerospace industry
* Expertise in technical theory of mechanical engineering areas such as structural and dynamic analysis, fracture mechanics, material science, structural analysis methods as well as design for manufacturing
* Experience in practical fundamentals such as manufacturing processes, product design and
development, mechanical design, lifecycle testing and mass production techniques that reduce costs of goods while maintaining high levels of quality and reliability
* Background in product development for medical devices, particularly in the areas of assistive technology and wheelchair mobility. Experience includes mechanical design, design for manufacturing and assembly, product durability testing and clinical trial study development.
* Experience leading teams and projects through design cycles with a strong emphasis on team-based processes that promote collaboration through brainstorming sessions and peer reviews

Type of services I can provide:

• Structural/stress analysis of components/structures/systems using both linear and nonlinear analysis (using both FEA and analytical methods) to assess the structural integrity and/or provide redesign and optimization options

• Dynamic analysis of systems (rigid body motion) to assess functionality, derive loads or calculate kinetic or kinematics of the system.

• Lifecycle analysis including fatigue and fracture analysis (using FEA, NASGRO and analytical methods) of systems or components including both high cycle and low cycle fatigue, development of loads and load cycles as well as mitigation strategies

• Structural dynamics analysis (using the FEA and analytical methods) including vibration and modal response of components and systems

• Mechanical design and development of systems or components to meet functionality and structural integrity requirements

• Development of custom analytical tools using Python, Excel or Visual Basic/Excel to meet the needs of the user whether that be a method for reanalyzing system for basic changes in configuration and/or loading, for calculating more complex scenarios and systems or for processing data from testing.
