Community Manager Colonial Contract Labor - IISH

The project focuses on the collection of new event datasets on collective action and forms of resistance by indentured laborers working in Dutch colonies after the abolition of slavery. In line with the global labor history research agenda, it aims to complement current scholarly attention to the history of slavery with the study of the coercive labor regime of contract labor that became even more widespread after abolition.

The goal is to gather new knowledge and to make visible the various ways in which Chinese, Indian, and Indonesian indentured laborers resisted the conditions of the appropriation of their labor power in the Dutch Empire.

This project builds on ongoing research into the history of workers' collective action around the world as part of the Hub Global Labor Conflicts data platform project at IISH. Embracing the idea of citizen science, we aim to actively involve descendants of former contract laborers or members of the different affected communities in guiding this project, including developing research questions, identifying sources, and collecting data.

The project is embedded in a citizen science project of the Humanities Cluster of the KNAW. With this collaboration, the IISH, Meertens and the Huygens Institute aim to promote the democratization of historical research and cultural heritage projects.

What you will be doing
As a Community Manager, you will work closely with two researchers at the IISH, as well as with two similar teams at the partner institutions. Your responsibilities will include helping to build engagement with relevant communities, organizing community spaces and events, and helping to organize and communicate research.

Water4all EcoTwin Postdoc - NIOO-KNAW - Wageningen

For the NWO Water4All project EcoTwin, we are looking for an enthusiastic transdisciplinary post-doctoral researcher. EcoTwin aims to leverage the transformative potential of digital twins for the better integration of ecosystem services in water resource management, focusing on flood/drought regulation, irrigation, habitat provisioning, recreation, water supply, carbon & nutrient management. While traditional modeling methods have laid the groundwork for assessing ecosystem services,digital twins offer an exciting opportunity to revolutionize this field.The post-doctoral researcher will contribute to Ecotwin by -together with stakeholders- develop ecosystem services modules for integration in lake digital twins . In addition, the post-doctoral researcher is charged with the development of user interface that facilitate the uptake of lake digital twins by decision makers.

ICT Beheerder Linux - NIOO-KNAW - Wageningen

Ben jij een ervaren Linux beheerder met een passie voor datamanagement en innovatie? Wil jij werken in een inspirerende wetenschappelijke omgeving waar je bijdraagt aan baanbrekend ecologisch onderzoek? Dan zijn wij op zoek naar jou!

Het Nederlands Instituut voor Ecologie (NIOO-KNAW) is een gerenommeerd onderzoeksinstituut dat zich richt op ecologisch en biodiversiteitsonderzoek. Voor de ondersteuning van onze onderzoekers beheren wij ons eigen datacenter en IT-infrastructuur. Hier maken we gebruik van grote datasets en innovatieve technologieën.

Dit ga je doen
Als ICT Beheerder Linux ben je samen met de collega’s van de sectie ICT verantwoordelijk voor het beheer van ongeveer 50, deels virtuele, Linux- en Windows-servers en JBOD-storage. Je zorgt ervoor dat onze IT-infrastructuur optimaal functioneert en ondersteunt het onderzoek met stabiele en veilige systemen.

Jouw taken omvatten onder andere:

• Beheer en onderhoud van servers en storage-oplossingen;
• Uitvoeren van reguliere updates en systeemvervangingen;
• Afhandelen van incidenten en uitvoeren van changes;
• Adviseren over innovaties op het gebied van energieverbruik en technologie;
• Actief bijdragen aan de verbetering van security en backup & restore strategieën.

PhD NWA -SPARKLES - NIOO-KNAW - Wageningen

For the NWA project SPARKLES, we are looking for an enthusiastic Phd Candidate. The project aims to bridge the gap between the technological societal and environmental science domains in the context of floating solar, with the aim of nature-inclusive upscaling of this emerging technology. The emerging FPV field is rife with uncertainties and unknowns in terms of optimal design, environmental and societal impacts. Nonetheless, the potential of FPV on inland waters is huge. Floating solar panels on inland waters are embedded in a landcape with potential impacts both for aquatic as well as terrestrial ecosystems.The PhD candidate will generate knowledge on the impact of floating solar on the ecology of land and waterscapes, through a.o. deployment of a range of smart participatory science approaches (e.g. citizen observations, cheap sensor deployment) together with local water users, water owners, companies and governments. In addition, the Phd candidate is expected to translate the observed ecological impacts to consequences for human uses of water and surrounding land.

Postdoc Climet - NIOO-KNAW - Wageningen

You will be working on the CLIMET project (Climate feedbacks and methane cycling in Arctic lakes: enzymes to atmosphere).

The recent increase in atmospheric methane is attributed to an imbalance between microbial production and degradation. Methane emissions from warming Arctic lakes are an important climatic feedback loop, potentially contributing to this imbalance. Alongside warming, the input of organic carbon as well as the input of glacial dust, containing elements (among which rare earth metals), affects methane cycling in arctic lakes. The CLIMET project team will map the impact of organic carbon and lanthanide-containing glacial dust on the Arctic methane cycle from the genes involved to the impact on methane emission from Greenland's lakes.

You will be executing a field sampling campaign in Greenland to collect material for (lake water; glacial dust) for laboratory experiments which will be carried out in close cooperation with another Postdoc and PhD student to be recruited. In laboratory settings, you will investigate lake-derived methane-cycling microbial communities under influence of DOM/glacial dust combinations and its effects on methane emission. Biotic interactions with other microbes, phyto- and zooplankton will be a major focal point as is the link between methane and nitrogen cycling under anoxic conditions. The successful execution of these experiments will entail a combination of classical microbiological (cultivation, microscopy), chemical analytical (GC, GC-MS, GC-IRMS, GC-TOF-MS, ICP), molecular biological (QPCR, metagenomics, transcriptomics) as well as stable isotopic cell-labelling techniques (NanoSIMS, GC-IRMS-PLFA), flowcytometry). The experiments carried out will be interlinked with the partners at Radboud University and Utrecht University.

What will you be contributing?

• Executing field sampling campaigns in Greenland lakes (July 2025).
• Work closely together with the NIOO PhD student on assessing effects of DOM and glacial dust on biotic interactions affecting methane cycling in various laboratory settings.
• Setting up methods and protocols (Isotopic labeling, single-cell analyses etc).
• Develop a flow-through column-based lab system to study the effect of biotic interactions on methane emission as influenced by glacial dust-DOM combinations.
• Contribute to the development of the project as it evolves.
• Closely collaborate and coordinate activities with other ClIMET team members.
• Publish results in scientific journals.
• Participate in outreach activities.
• Contribute to maintaining a friendly, welcoming and collaborative environment within the group.
