Background information

• Ph.D. in Applied Mathematics
  The University of Sheffield
  Starting date: 01-02-1997
  Finishing date: 28-11-2000
  Subject: Shallow water predictions and HF radar measurements of waves in coastal waters
  Supervisor: Prof. L. R. Wyatt

  My thesis involved research in three main areas: calculation of directional wave spectra from high frequency radar measurements; dynamical modelling of ocean waves; statistical methods for the comparison of data sets.

• M.Sc. in Naval Architecture and Ocean Engineering
  The course resulted from an agreement between Instituto Superior Técnico and the University of Glasgow, and comprised a period of 18 months in Lisbon and a period of 6 months in Glasgow.
  Starting date: 01-01-1995
  Duration: 2 years
  Subject: Onboard wave forecasts
  Supervisors: Prof. C. Guedes Soares, Dr. K. S. Varyani.

  The final output of the MSc. thesis was a method enabling a simple and effective way of forecasting wave conditions on board of ships. This involved running an assimilated wave model on a ship-based PC, making use of ship wave observations and possibly other data, and was shown to be useful for providing wave forecasts along different ship routes.

• Degree in Naval Engineering
  Instituto Superior Técnico
  Starting date: 15-01-1990
  Duration: 5 years
