Curriculum Vitae

You can have a look at the complete list of my peer-reviewed publications, and my complete CV can be accessed here (HTML file) (PDF file).

You can also access a list of peer-reviewed publications in the ULg ORBI repository (with access to pdf version of the papers by request)

Also in ORBI, there is a more complete list of all my publications and communications

Research Interests and Recent Work


Daily Mediterranean Sea SST reconstruction using DINEOF at

Geophysical data sets, such as those obtained from satellites, often contain gaps (missing values) due to the presence of clouds, rain, or simply due to incomplete track spatial coverage. There is a rising need, however, for complete data sets at the global, regional and local scale: several analysis methods, input for hydrodynamic models and data visualization are examples of applications where complete data sets are preferred or even necessary.

DINEOF is an EOF-based method to fill in missing data from geophysical fields, such as clouds in sea surface temperature. Based on Empirical Orthogonal Functions (EOFs), DINEOF uses an iterative procedure to calculate the values at the missing locations. The source code is open and available for everybody (see links below).

Help pages (download, installation instructions, etc)
An example of an operational application: Daily reconstruction of the Western Mediterranean SST

Cariaco Basin model

Cariaco 3D hydrodynamic model on Venezuela (more info to come)
