Alfred Roubos is currently a researcher at TU Delft in the field of maritime structures. In 2019, he finished his PhD research which aimed to improve port performance by performing reliability-based assessments of quay walls. His research contributes to a better understanding of uncertainties, hidden safeties and reliability in hydraulic engineering. One of the objectives is to acquire more insight into the actual performance of maritime structures in order to ensure safety and support decision making processes. Alfred is also employed at the Port of Rotterdam Authority and participates in various types of projects regarding the development of new ports, expansion of existing terminals and dredging works. He holds a MSc degree of the faculty of Civil Engineering and Geosciences of the Delft University of Technology, with a specialization in hydraulic structures and probabilistic design. In 2007, his master thesis “Dealing with uncertainties in the design of bottom protection near quay walls” was awarded with the PIANC Paepe Willems Award. Alfred is a member of several national (CROW, NPR, NEN) and international committees (PIANC, CEN). He was secretary of the committee updating the CUR211 Handbook Quay Walls, editor of CUR186 a new handbook Historic Urban Quay Walls and editor of CUR206 Handbook Flexible Dolphins. On behalf of the Netherlands, Alfred participates in PIANC and Eurocode technical working groups. Since 2006 Alfred is involved in several research projects preliminary focusing on port developments and maritime structures, e.g. quay walls, jetties, flexible dolphins and scour protection. Alfred is a lecturer of several post academic courses and worked in the past for the Rotterdam University.  His teaching and research interest include: 

• Design and assessment of quay walls in fully operational port districts.
• Assessment of historic urban quay walls adjacent to city centres.
• Design and assessment of jetties and flexible dolphins.
• Design of bottom protection near marine structures and revetments.
• Probabilistic design of quay walls and bottom protection near quay walls.
• Berthing, mooring configurations and fender design.
• Design of flexible dolphins.
• Dredging works in sheltered port districts.
• Port development  and master planning of marine terminals
