  MWL, Department of Aeronautical and Vehicle Engineering, KTH

  Sept 2008 - Mar 2013

  PhD student

  Programme: Technical acoustics.Department of Aeronautical and Vehicle Engineering Marcus Wallenberg Laboratory for Sound and Vibration Research (MWL)The PhD investigated the sound insulating properties of structures such as building construction double-walls and multi-layered panels featuring porous materials used in the car industry; the novel formulation of elements for the statistical energy analysis of those structures required me to devise original self-adjoint variational principles for non-conservative media, specifically porous materials either described by equivalent fluid theory or Biot's equations. These variational principles became useful for a better understanding of the underlying physics of the media and as a basis to formulate waveguide finite elements to reveal the wave motion in the coupled multilayered structures. Original acoustics measurements for defining some of the vibroacoustic properties of porous materials relevant to Biot's theory have been developed working closely with other colleagues in MWL; that and standard acoustic measurements allowed to obtain inputs for statistical energy analysis model and to have data to compare results with.The research path mixed theoretical studies to calculations to acoustic measurements, and focused both on the latest development of research in vibroacoustic and on the needs of industry.PhD partly funded by Vetenskapsrådet (Swedish Research Council) and EU-project Mid-Mod.

  Lloyd's Register Consulting

  Apr 2013 - Mar 2016

  Senior Consultant, Noise and Vibration, Marine

  Consultant for noise and vibration in the marine sector, dealing with measurements and predictions of various kinds of ships, from tankers to LNG vessels to cruise vessels to mega-yachts to cargo ships. Field tasks involve sea trial measurements for noise and vibrations in public, private and machinery spaces, troubleshooting, verification measurements for compliance to class rules or specifications. Office tasks involve noise predictions, finite element analysis (strength analysis and free/forced vibration analysis), room acoustic and outdoor noise propagation calculations, laboratory measurements of acoustic properties, review of noise reports and yard/owner's specifications, writing of proposals. Typical clients are both yard and owners in the global marine business.Safety leader of Copenhagen office (OHSAS 18001, safety culture, internal safety courses and briefings, PPE procurement).
