    EMPLOYMENT HISTORY

    June 2018 – Present     Research Fellow II at the University of Surrey funded by an EPSRC Fellowship won under the program “EPSRC UKRI Innovation Fellowships” with a project titled “From Virtual Vibration Testing to a Digital Test Facility for Spacecraft”. This involves virtualisation of the thermal and thermal optical tests for spacecraft in addition to vibration. The Fellowship is fully funded for 3 years.

    Mar 2015 – June 2018   Research Fellow I at the University of Surrey working on a European Space Agency/Airbus Project “Virtual Shaker Testing for Spacecraft Structures – Feasibility and Preliminary Modelling Approach”. A tool based on virtual testing concepts was developed and validated against real spacecraft test campaigns using Nastran, Matlab, Simulink and Isight modelling capabilities. Co-Supervisor of several PhD students in the “Structures and Mechanisms Group” at the Surrey Space Centre.

    Oct 2014 – Mar 2015      Contractor for Surrey Satellite Technology Limited (SSTL) working on: structure qualification of Artes, vibration analysis of Alsat and FE modelling (Patran/Nastran) of UrtheCast.

    Jan 2013 – Mar 2013     Contractor for Surrey Satellite Technology Limited (SSTL) working on microvibration analyses for the satellite SSTL 300 S1 (Break from PhD studies when moving from Southampton to Surrey)

    Oct 2010 – Dec 2014     Research Assistant at the University of Southampton in the Astronautic Research Group, registered as a PhD student (moved to University of Surrey in April 2013) under the supervision of Professor Guglielmo Aglietti, working on the project “Modelling Micro-Vibrations Transmissions in Spacecraft Structures”, an ESA project awarded to SSTL and University of Southampton. In charge of structural analysis (Static and Dynamics) using FEM and Stochastic FEM. Responsible for carrying out vibration testing for internal and external clients using shaker / slip table at the University of Southampton. Demonstrator for the “beam bending and beam torsion” lab for second year undergraduates. Teaching assistant for the “mechanics of solids” course for first year undergraduates.

     

    TECHNICAL SKILLS AND EXPERIENCE

    Strong skills in structural dynamic analysis with expert use of Nastran and Patran software, including DMAP Programming to create bespoke Nastran functions.

    Extensive experience in vibration testing, both with smaller structures in University laboratories and full-size spacecraft.

    Extensive knowledge of numerical-experimental correlation criteria and finite element model updating, also including optimisation techniques (good use of I-Sight software).

    Good knowledge of acoustic testing and analysis.

    Strong skills in Matlab & Simulink, including SDTools functions for Nastran interface.

    Good use of CAD software, such as SolidWorks.

    Strong presentations skills.

     

    ACADEMIC ACHIEVEMENTS

    Strong publication record (see list attached) and reviewer for papers in most reputable engineering journals as an expert in the field.

    Developed novel methodology for faster Monte Carlo Simulations for spacecraft structures, named Craig-Bampton Stochastic Method (CBSM).

    The work produced during my postdoc underpinned the Keynote Talk on virtual testing given by Prof Guglielmo Aglietti (at the time my supervisor for the project) at the ECSSMET international conference in Toulouse (2016) and the ATS conference in Los Angeles (2018).
