Medewerker studentenzaken

De studieadministratie is één van de teams binnen ons onderwijsbureau. Dit team bestaat uit 6 medewerkers, waaronder een teamleider. Het team is verantwoordelijk voor de uitvoering van een aantal onderwijsondersteunende processen. In verband met het vertrek van een collega zijn wij op zoek naar een nieuwe medewerker studentenzaken, een administratief talent met affiniteit voor IT.

Als medewerker studentenzaken heb je een afwisselend takenpakket. Samen met een collega ben je verantwoordelijk voor de organisatie en uitvoerig van de toetsafnames (zowel digitaal als schriftelijk) voor al onze opleidingen. Je registreert en verwerkt cijfers in SAP/SLcM en je bent verantwoordelijk voor het uitvoeren van het administratieve proces met betrekking tot contract- en bijvakstudenten. Verder ondersteun je bij de uitvoering van overige werkzaamheden binnen het team, afhankelijk van de werkverdeling. Je voorziet alle betrokken partijen (studenten, docenten en collega’s) van de benodigde informatie, je biedt hulp, beantwoordt vragen en geeft advies als dat nodig is.

PhD Position in Number Theory and Formalization

The Department of Mathematics of Vrije Universiteit Amsterdam welcomes applications for a fully-funded, 4-year PhD position in Number Theory and Formalization.

The candidate will conduct research on both developing and formalizing (with a proof assistant such as Lean or Rocq) number theory necessary for solving Diophantine problems. The focus will be on effective/algorithmic number theory, but more "pure" results will also play an important role. It will be supervised by Sander Dahmen (daily supervisor) and Assia Mahboubi. The position also contains a small teaching component.

The research is part of Sander Dahmen's NWO-funded Vici project Towards formalized Diophantine research: bridging the gap. It will be embedded in the Center for Topology, Algebra, and their Applications at the Mathematics Department. We are an inclusive, interdisciplinary group, and diversity and internationalism is at the heart of our research principles, as well as our teaching practice.

The preferred starting date is September 1, 2026 (but somewhat later is also possible).

Applications from all groups currently under-represented in academic posts are especially encouraged. We particularly welcome applications from women and people with an ethnic minority background.

Your duties

• doing research towards writing a PhD thesis
• teaching tasks (roughly 15% of your time), for instance supervising exercise classes

Researcher (Department of Paediatric Dentistry)

To strengthen the Department of Paediatric Dentistry, ACTA is looking for a researcher to contribute to innovative research in the field of oral health, with a particular focus on paediatric dentistry.

As a researcher within the Department of Paediatric Dentistry, you will contribute to ongoing research projects in the field of oral health, with a particular focus on preventive strategies and treatment of paediatric patients. You will be involved in the design and execution of experimental and clinical studies, data collection and analysis, and the dissemination of research findings. The
research is embedded in a multidisciplinary setting, requiring close collaboration with clinicians, researchers, and other healthcare professionals. In addition, you will contribute to the development of new research proposals and support or lead grant applications to secure external funding. You will present your work at national and international conferences and contribute to publications in peer-reviewed scientific journals.

Your duties
During your time at ACTA, you will perform a combination of the following activities:

• design and conduct research within the field of paediatric dentistry, including

clinical and laboratory-based studies

• perform data collection, management, and quantitative analysis
• contribute to the development of research protocols and methodologies
• prepare scientific publications and present findings at national and

international conferences

• collaborate with clinicians and interdisciplinary research teams
• supervise undergraduate and master’s thesis projects
• contribute to the development of research proposals and grant applications
• support ongoing research projects within the department

Overgewicht en obesitas komen bij mensen met een dwarslaesie extreem vaak voor (~75%) en leiden tot ernstige gezondheidsproblemen zoals hart- en vaatziekten, doorzitwonden, conditieverlies en verminderde participatie. Dit vergroot niet alleen de druk op het zorgsysteem, maar beperkt ook de kwaliteit van leven. De huidige revalidatiezorg is vaak niet effectief in het voorkomen van overgewicht en obesitas, noch in het bereiken van relevante gewichtsvermindering. Zodra mensen met een dwarslaesie na een intensieve revalidatieperiode weer thuis zijn, ontbreekt vaak de expertise bij eerstelijnszorgverleners om deze complexe groep effectief te coachen op leefstijl. Innovatieve oplossingen zijn dus dringend nodig.

Daarom is in het RAAK-publiek project VIVENDI een transmuraal leefstijlcoachingspad ontwikkeld, inclusief een aangepaste gecombineerde leefstijlinterventie CooL-MiGuide, speciaal voor mensen met een dwarslaesie en verhoogd gezondheidsrisico. Alvorens dit leefstijlcoachingspad geïmplementeerd kan worden als reguliere zorg dient wetenschappelijke evaluatie plaats te vinden.

In het RAAK-PRO promotieonderzoek STOP-ObeSCIty zal dit leefstijlcoachingspad dan ook worden geëvalueerd op:

• Effectiviteit ten aanzien van het voorkomen of reduceren van overgewicht en obesitas
• Impact op beweging, voeding, gezondheid en welzijn
• Kosteneffectiviteit
• Beperkende en bevorderende factoren voor landelijke implementatie

PhD Position: Economic Assessment of Coral Reefs and Coastal Ecosystems

The Institute for Environmental Studies (IVM) has a new position for a PhD student in the field of environmental economics. As PhD student you will become part of the new interdisciplinary Horizon Europe project ‘Management of Coastal Networks Nurtured through Ecosystem assessment, Collaboration and Technology’ (m-CONNECT). It focuses on interconnected coastal seascapes (CMS-metasystems), i.e. coral reefs, mangroves and seagrasses, and their role in supporting ecosystem services and climate resilience. The project aims to better understand how different forms of ecological connectivity influence services like fisheries, coastal protection and carbon storage. Working with Indigenous Peoples and Local Communities, the project will develop science-based, locally informed guidelines for conserving and restoring these systems across islands in Southeast Asia and the Western Pacific.

The main tasks for you as PhD within the project are to:

• Design and apply economic valuation methods to assess the value of ecosystem services provided by coral reefs, mangroves, and seagrasses, including tourism, fisheries, coastal protection, carbon storage, and biodiversity.
• Conduct empirical research in selected case study sites using stated preference methods (e.g. discrete choice experiments) to derive non-marketed benefits among local communities.
• Support approaches to extrapolate local natural capital valuations to broader spatial scales, supporting regional policy applications.
• Apply societal cost-benefit analysis (CBA) to evaluate the economic viability, trade-offs, and distributional impacts of different conservation and restoration strategies across stakeholders.
• Compile and analyse global data on restoration costs and financing instruments through systematic literature review and stakeholder engagement.
• Design and assess innovative and sustainable financing mechanisms to support long-term conservation and restoration.

You will work closely with ecologists, social scientists, policymakers, and stakeholders, including Indigenous Peoples and Local Communities. An interdisciplinary and transdisciplinary mindset, as well as strong communication skills, are therefore essential.

Your duties

• You publish research results in international peer-reviewed journals
• You teach for 0.1 FTE in Bachelor and/or Master’s educational programmes and supervise Bachelor and Master students
• You contribute to project tasks, meetings and activities
• You present your research findings, for example at international conferences
