    Curriculum Vitae

    D.O.B.: 14/01/61

    Skill summary:

    Over 20 years experience in applied FE analysis (mainly MSC-NASTRAN) in Spacecraft structures and sub-systems. Principal expertise focused in structural dynamics spanning frequency response, random vibration, SRS based methods, transient and non-linear static and dynamic analysis.

    My personal perception is as a practical engineer with experience of engineering hardware, design, specification and testing who is able to support practical experience in design and manufacture with an analytical capability.

    In my current role, as Snr Specialist, I am technically responsible for a group of Spacecraft Prime mechanical analysts and have recently been promoted to the EADS technical experts roster (EADS 2%) having been Systems Team Leader for over 8 years. I take pride from an ability to work with other people and see myself as a team member / player who can when necessary work on his own initiative to meet business, team or personal goals.
