Assistant Professor in (arithmetic) algebraic geometry and number theory

You are a researcher who is eager to play an active role in all aspects of academic life in our department, with a balanced commitment to both research and teaching. You welcome opportunities for collaborations with members of the Utrecht Geometry Centre or the University at large. You will apply for external funds, alone or in consortia, to build and sustain your own strong research programme. In addition, you will supervise PhD candidates and postdocs, and organise relevant scientific meetings at a national or international level.

You will teach courses at a variety of levels, ranging from first-year undergraduate to advanced Master’s courses. This may also include service teaching. Master’s courses can be taught locally or as part of the national Master's programme, Mastermath. Teaching will account for 50% of your job, with a typical teaching load of approximately 120 contact hours per year. You will also supervise Bachelor’s and Master’s theses as well as smaller-scale projects. We encourage innovation in teaching; the University provides funding to support promising ideas.

By engaging in the daily life of the Mathematical Institute and taking on positions of responsibility, you will help shape the future of the department.

Please note that we are also looking for an Assistant Professor in Mathematical Modelling. More information about this position is available on our website.

Assistant Professor in Mathematical Modelling

In this position, you will divide your time roughly equally between research and teaching (approximately 50% each).

You will further develop your research line individually and in collaboration with other scientists, including colleagues from other departments. You will apply for external funds, supervise PhD candidates and postdocs, and organise relevant scientific meetings at national or international level. You will also actively initiate efforts, or continue to apply, your research to real-world problems in medicine, biology, climate, physics, imaging, or other domains.

You will teach courses at a variety of levels, from first-year Bachelor's to advanced Master's courses. Master’s courses can be taught either at the local level or as part of the national master programme, Mastermath. You will be involved in the supervision of Bachelor's and Master's theses as well as smaller-scale projects. We value and encourage teaching innovation, offering University funding opportunities for developing new ideas and methods.

Senior HR-adviseur

Jij bent een adviseur met ruime ervaring in- en passie voor het HR-vak. Je hebt affiniteit met het (universitair) onderwijs, je voelt je thuis in de academische wereld en je kunt je goed verplaatsen in wetenschappers en degenen die hen ondersteunen. Je werkt vanuit verbinding en je durft ook de kritische spiegel van je gesprekspartners te zijn. Je draagt eraan bij dat ieder perspectief gezien en gehoord wordt en je komt ook zelf met vernieuwende perspectieven en ideeën. De combinatie van interessante HR opgaven en het samenwerken in een open en gedreven, maar soms ook complexe en politieke omgeving maken deze rol voor jou extra interessant.

Je hebt een professionele visie op alle facetten van het HR-vak en je bent een gelijkwaardige en krachtige sparringpartner voor bestuur en leidinggevenden. Je ondersteunt hen niet alleen met advies, maar ook met concrete acties en resultaten. Naast de dagelijkse HR-adviespraktijk binnen de faculteit ben je actief en projectmatig betrokken in strategische HR thema’s zoals: strategische personeelsplanning, leiderschapsontwikkeling, diversiteit en inclusie en een sociaal veilige werkcultuur. Je bent enthousiast en gedreven en kunt dit in de dagelijkse praktijk ook goed combineren met een gezonde dosis humor en relativering.

Door de bezuinigingen in het hoger onderwijs bevindt de faculteit Geesteswetenschappen zich in een periode van transitie. Dit brengt naast veranderingen zoals het aanpassen van het bachelor onderwijssysteem ook uitdagingen met zich mee als omgaan met werkdruk en aandacht voor welzijn. Je speelt een actieve rol in het begeleiden van deze periode van veranderingen en ondersteunt het departementsbestuur met deze onderwerpen.

Belangrijkste activiteiten:

• Je adviseert (gevraagd en ongevraagd) bestuurders en leidinggevenden over HR-beleid en je ondersteunt bij de strategische inzet en/of de toepassing van HR-instrumenten en wet- en regelgeving;
• Je adviseert en ondersteunt bestuurders en leidinggevenden in het tonen van leiderschap conform de universitaire en facultaire visie op leiderschap;
• Je adviseert en ondersteunt bij complexe casuïstiek- en dossiers;
• Je leidt of neemt deel aan HR- (gerelateerde) projecten binnen en buiten de faculteit;
• Je bent verantwoordelijk voor één of meerdere HR-beleidsthema’s binnen de faculteit.

PhD Position in Chemical Proteomics

In this project, you will apply chemical proteomics strategies in cells and tissues to study the role and regulation of protein lipidation and drug target engagement, in (neuro)inflammatory disorders. You will be combining click chemistry, tissue culture, and proteomics mass spectrometry, developing and applying new analytical strategies to identify new therapeutic opportunities.

You will undertake a challenging and multidisciplinary PhD project in an international team with a broad spectrum of expertise. Throughout the course of this PhD project, you will grow into an independent scientist and expert in chemical proteomics.

You will join a multidisciplinary laboratory with world-leading expertise and infrastructure in proteomics and mass spectrometry. Our lab combines state-of-the-art chemical proteomics with in-house molecular biology and tissue culture facilities. This environment provides a unique opportunity to develop and apply pioneering strategies to study protein lipidation, as well as drug-target engagement and selectivity using advanced chemical proteomics approaches.

PhD Position in Paleoclimatology

You will work on the project called “Eemian sea level”. In this 4-year fully funded position, you will combine 2 toolsets: generating proxy data reflecting surface ocean changes, and simulations of sea level changes using comprehensive ice sheet models.

The sea level in the Eemian was much higher than today, 3 to 6 m or even higher. The high sea levels during the Eemian cannot be explained by a complete melting of the Greenland ice sheet, as large parts of it survived the Eemian stage. This implies that the Antarctic ice sheet was also very vulnerable to melting during this period, but little model studies are done on the Antarctic contribution. The aim of this research project is to further investigate the timing of major sea level changes, and thus the contribution of the Greenland and Antarctic ice sheets during the Eemian by generating high-resolution proxy records from the Dutch subsurface, including the type locality of the Eemian near the city of Amersfoort. Special emphasis will be on the varying background conditions between the Saalian to Eemian transition (i.e., termination II), when large ice sheets formed the Dutch coastline and the adjacent North Sea, and that of the LGM-Holocene transition (i.e., termination I), when large ice caps lay further north. The comparison between these new datasets and experiments with ice sheet models could lead to a better long-term projection of the Greenland and Antarctic ice sheets in our warming world.

The project is highly multidisciplinary and collaborative. Proxy data will amongst others infer the stable isotope composition of foraminifera and mollusc shells, since not much is known about the changes in temperature and isotopic composition of the waters flooding the Netherlands and other parts of Northwest Europe during past interglacial periods, such as the Eemian. The study is expected to shed new light upon (1) the timing and possible cause of rapid sea level changes during the Eemian, and (2) the complex interactions between global warming, sea level changes, glacial rebound and sediment transport on a more regional scale.

The position is part of the Earth System Feedback Research Centre (EMBRACER), which focuses on the carbon and water cycle feedbacks within the climate system. EMBRACER includes 23 PIS from a wide variety of disciplines, from physics, environmental, earth and social sciences in the Netherlands. The EMBRACER community of students and staff will have regular cross-disciplinary meetings, events and lots of opportunities to get in contact with the wide spectrum of climate science. The project will also have close links with Past to Future (P2F), a 4-year Horizon Europe research project which was launched in March 2025, consisting of 24 partners from a wide-range of disciplines in future climate model development, paleo-climate data collection, and applied mathematics.
