has a degree in electrical and mechanical engineering, and a doctorate in applied sciences (mechanics). His research interests focus on the development and use of unstructured-mesh models for simulating geophysical and environmental fluid flows, as well as the related ecological processes. His domains of interest comprise most of the hydrosphere, i.e. lakes, rivers, estuaries, coastal regions, shelf seas and the World Ocean.
He is coordinating the SLIM project (Second-generation Louvain-la-Neuve Ice-ocean Model, www.climate.be/slim) and he is the co-founder of the Constituent-oriented Age and Residence time Theory (CART, www.climate.be/cart)
He has held research or teaching positions in Belgium and abroad. He currently is a reader at the Université catholique de Louvain (Louvain-la-Neuve, Belgium), where he is lecturing on several aspects of mechanics. He is also an honorary researcher with the Belgian Fund for Scientific Research (FRS-FNRS, www.fnrs.be). On October 1st, 2014, he accepted a five-year, part-time professorship in applied mathematics at the Delft University of Technology (Delft, The Netherlands, www.tudelft.be).
Additional pieces of information may be found on his website (www.ericd.be).

PhD and Post-doc researchers under my supervision:


Modelling and diagnosing transport processes in a tropical river-lake-delta-sea continuum Application to the Mahakam River (Borneo Island, Indonesia)
Insaf Draoui

The project aims to model and diagnose transport processes in the Mahakam delta using a coupled 1D-2D model. The model will be based on SLIM. Advanced diagnostic methods will be inspired by CART and pertain to both water and sediment. In addition, an attempt will be made to apply the newly-introduced concept of partial age to sediment.


Development of the 3D model of SLIM
Ange Ishimwe

SLIM is a simulation software which resolves the hydrodynamical equation with the use of finite elemnts. My goal is to developpe and improve the 3D model of SLIM. The two criteria are the precision of the results and the computation speed.
