Distinctions
  • Christian Le Provost was a french oceanographer with an impressive legacy in the area of tides and operational oceanography. A "Christian Le Provost, Oceanographe" award was created in 2009 to reward the work of a young french oceanographer. I was particularly happy to receive the Christian Le Provost award in 2010. I was one of Christian pupils in the course he was giving about tides at ENSTA, and I particularly enjoyed his teaching.
  • I have been collaborating with the CSIR-National Institute of Oceanography (Goa, India) since 2003. I am particularly proud and happy to have been appointed as  CSIR-NIO  "Adjunct Scientist"  for a period of 3 years starting from 29 September 2016.
