Our Student Contributors
Danai Chronopoulou
Graduate Civil Engineering
Danai is currently doing her graduation project at Coastruction as part of her Master’s degree in Civil Engineering at TU Delft. Specialising in Hydraulic Engineering, she is testing the hydrodynamic stability of a Coastruction's 3D-printed artificial reefs. Her research involves conducting experiments in the Scheldt Flume at Deltares, subjecting the proposed reef designs to forcing conditions that simulate real-life environments found on fringing reefs. The results of her work will provide a strong technical foundation for identifying the key challenges that must be addressed to ensure proper installation and long-term stability of artificial reef restorations.
Cecile Hagen
Graduate Coastal and Marine Management
Cecile is a graduating student from Van Hall Larenstein University of Applied Sciences, joining Coastruction to do her project in marine ecology. She enjoys the best of both world, working both in the field and in the laboratory. Cecile's interests lie in artificial reefs, marine organisms, and ecosystem functioning. At Coastruction, Cecile is exploring biofilm formation on our Purpose‑Built Reefs and how different material compositions influence early colonisation. She is also collaborating with our partners to design experiments that track organism behaviour and settlement on our structures.
Our Experts
David Lennon
Artificial Reef Design and Market Expert
Expert in the design of artificial reefs and reef layouts with more than 25 years of experience in the industry globally. He has founded 4 artificial reef companies and designed and patented reef unit designs. He first used a particle bed printer to print reef units back in 2012 and is passionate about innovation and advancing artificial reef design, therefore is excited to help Coastruction.
Creative Designer and Product Developer
Antoine is a designer who is passionate about scuba diving and the underwater world. After a master's project focused on coupling artificial reefs with blue electricity production solutions, he sought to serve nature through design and met Coastruction and its incredible 3D printing technology. He is now involved in the creation of modular artificial reefs, sculpting and refining models so that they assemble and blend easily into coastal ecosystems.
Marketing and Communications Advisor
Georgy is an international marketing advisor with a strong background in business development, sales, and strategic growth. Drawing on his experience lecturing in marketing and communications, he combines analytical expertise with creative problem-solving and a people-centered approach. A passionate trail runner and outdoor enthusiast, he believes businesses play a vital role in protecting nature and is committed to helping them grow responsibly and sustainably.
Carlos Rego
Multidisciplinary Designer, Biomimicry Expert
With a broad experience in delivering sustainable and innovative Nature driven solutions, Carlos is our external expert in Design and Biomimicry Thinking, ensuring the full adoption of these methodologies in the research, development and implementation of the Coastruction products, processes and systems. His work has been internationally recognised with several major design awards.
Civil Engineer, Computational Designer
Paolo is a civil engineer from Italy. His expertise lies in development of parametric algorithms which are key for creating modular artificial coral reefs. Paolo is collaborating with Coastruction to ensure that projects are well-engineered and 3D printed structures withstand the tough conditions of Mother Nature.
Our Previous Contributors
Graduate Industrial Product Design
Judie Hoekstra is working on her graduation project at Coastruction and is studying Industrial Product Design at Rotterdam University of Applied Sciences. Her project focuses on improving and modeling the interface between separate modules of a Coastruction PBR.
With her design background, she contributes to innovative solutions for modular constructions, aiming to develop a more efficient, stronger, and user-friendly interface.
Graduate Hydraulic Engineering
Passionate about coastal protection, Florine joined Coastruction as a Master's student in Hydraulic Engineering. Her graduation project focused on analyzing the effects of 3D-printed artificial reefs on wave attenuation. Through rigorous testing in Schelde flume at Deltares, she examined how different reef designs influenced wave transmission and dissipation. Her research underscored the ecological advantages of using complex, biomimicry-inspired structures, highlighting their potential as sustainable solutions for enhancing coastal resilience.
