My expertise is in the field of coastal morphology and wave transformation processes. This involves (1) understanding of the relevant physical processes, (2) skills to apply state-of-art models to answer relevant questions, (3) the ability to communicate results of research and consultancy projects in a clear and concise way and (4) pro-active attitude to initiate new research, acquire challenging projects and motivate other researchers. This communication takes place through reports, scientific papers and presentations. Most projects at Deltares focus on coastal morphology. This involves the assessment of the coastal impacts of structures (e.g. harbour moles or offshore wind farms), dredging in navigation channels, morphology of estuaries, bed composition changes in the marine environment and the stability of natural and artificial beaches. Furthermore, I have participated also in a variety of projects which aimed at the assessment of (design) wave conditions for coastal structures, wave penetration into harbours or the effect of ship waves. In the recent years, projects were also carried out which focused on the development of rapid assessment tools for policy makers to streamline and improve the process of policy making for the Dutch coast. Also software development part of the work. Sate-of-art models and data processing techniques are used to come up with relevant answers for these projects. One can think of mophodynamic modelling with Delft3D, Xbeach, ShorelineS and UNIBEST-CL+ (for which I am the principle developer), wave modelling (SWAN and PHAROS) and the application of a CFD model (ComFLOW), but also field measurements and physical scale models are made. Countries of work experience are The Netherlands, Belgium, Germany, United Kingdom, France, Portugal, Spain, Italy, Bulgaria, United States, Colombia, Dubai, Abu Dhabi, Iraq, Oman, S-A, Namibia, Senegal, South-Africa, Vietnam, India.
