Alex developed a strong background in soil mechanics and rheology during his MSc degree in Civil Engineering (cum laude). After his graduation, Alex conducted multidisciplinary PhD research in Applied Geophysics at TU Delft, where he developed novel geophysical surveying methods. Later, he carried out postdoctoral research, testing cost-effective maintenance strategies for ports and waterzays with mud. Currently, Alex is working as a Researcher/ Adviser at Deltares, bridging the gap between applied research and practice.

At Deltares in the Netherlands, a research team is developing a portfolio of technologies dedicated to the management of the finest and most challenging fraction of soft sediments. These technologies may unambiguously be called nature based because they make use of natural processes to enhance dewatering and strengthening, induce flocculation and the settling of fines, and protect the muddy bed from erosion.DOWNLOAD PDF Document | 2,7 MB
As regular maintenance and relocation of sediment deposits are highly expensive, Port authorities seek more efficient solutions for reducing the costs and CO2 emissions of maintenance dredging. One solution, water injection dredging (WID), is carried out for maintaining the sediment deposits which predominantly consist of clay and silt. WID has been proven to be a cheaper solution by leaving the sediment in place, eliminating substantial costs for relocation of the dredged sediment.DOWNLOAD PDF Document | 4,1 MB
Safe navigation through ports and waterways is determined by the space available under a ship's keel, but a seabed of fluid mud can get in the way.DOWNLOAD PDF Document | 2,76 MB
