Postdoc position: “Designing and engineering emergent trait-based mimics to restore coastal ecosystems”

The department of Coastal Systems (COS) at the Royal Netherlands Institute for Sea Research is looking for a motivated researcher to fulfil a 3-year Postdoc position. The position will be part of the NWO-funded Vici-project “Engineering emergent trait-based mimics to restore coastal ecosystems”. The aim of this position is to design and engineer naturally degradable structures that facilitate the restoration of habitat-forming species such as salt marsh plants, seagrasses, and reef-forming worms and bivalves. The position is within the group of Prof. T. van der Heide (NIOZ).

THE INSTITUTE

NWO-NIOZ Royal Netherlands Institute for Sea Research is the national oceanographic research institute. The mission of NIOZ is to perform academically excellent multidisciplinary fundamental and frontier-applied marine research addressing important scientific and societal questions pertinent to the functioning of oceans and seas. NIOZ also serves as national marine research facilitator (NMF) for The Netherlands scientific community, and stimulates and supports national and international marine research, marine education programs and marine policy development.

THE DEPARTMENT

COS examines how physical, chemical and biological processes interact to determine the distribution, composition and productivity of marine species - from primary producers to top predators - and marine habitats - from the coast to inter/sub-tidal and pelagic environments. Research is applied at both the regional and global scales to develop knowledge and methods needed for climate adaptation and mitigation and for biodiversity protection and restoration.

THE PROJECT

Coastal ecosystems that are shaped by habitat-forming species (so-called ‘biogenic ecosystems’), such as salt marsh plants, seagrasses, and reef-forming worms and bivalves provide vital services but are rapidly declining worldwide. Supported by the UN’s call to action in the ‘Decade on Restoration’ and ‘EU Nature Restoration Law’, governments, industry and nature organizations have increasingly embraced restoration as a vital tool to halt and reverse ecosystem losses. Unfortunately, restoration of biogenic ecosystems is failure-prone, because their stability hinges on self-facilitation generated by ‘emergent traits’, such as dense sediment-stabilizing root mats or strong and persistent reef structures. Such traits emerge when habitat formers aggregate, causing self-facilitation to only work beyond certain minimum patch size and density thresholds. This creates a ‘chicken-and-egg problem’ when ecosystem restoration is attempted on degraded systems. In this project, a multidisciplinary research team will test a new framework that combines methods from ecology, industrial design, and engineering to develop biodegradable or erodible structures that temporarily mimic key emergent traits using additive manufacturing techniques. The resulting prototype mimics should ‘kick-start’ establishment of the target habitat-modifying species, after which they are allowed to naturally degrade. Within the team, your role will be to coordinate the design and engineering process using a recently developed novel design framework that allows the development of prototypes tailored to specific species and conditions. In addition, you will develop new biopolymer- and “tras-cement”-based compound materials and test them for their suitability as structural materials for the mimics. Suitable materials will then be used to build prototype mimics at ~2x2x1m scales using an industrial-scale 3D-printer.

THE CANDIDATE

You must have completed your PhD degree in Industrial Design, Engineering, Material Science or a related discipline. Preferably, you will also have:

• Experience with general design approaches, additive manufacturing techniques and/or developing compound materials;
• A keen interest in performing multi-disciplinary work as part of larger research team;
• An interest in applying your expertise within the realm of coastal ecosystem restoration;
• A passion and capacity to work with ecologists, engineers, policymakers, and NGOs;
• Good collaborative skills, excellent written and oral communication in English.

NIOZ wants to be a transparent institute with a healthy working climate and an inclusive culture, where people from diverse backgrounds and gender bring their talents and further develop these talents. We aim for inclusive decision-making processes and expect our leadership to show visible commitment, awareness of bias, and cultural intelligence.
