Postdoc: Immune development in infants

Would you like to apply cutting-edge single-cell RNA sequencing to uncover why some infants respond better to vaccines or are more susceptible to infections? As a postdoctoral researcher at RIVM, you will research how the infant immune system develops and why responses to vaccines vary in early life. Working at the intersection of laboratory science, computational biology, and clinical research, you will build a broad repertoire across both wet lab techniques and data science. Your research will inform national public health strategies and help protect newborns during their most critical developmental window.

Dit ga je doen

In their first year of life, infants build the foundation for lifelong immunity, while transitioning away from the temporary protection of maternal antibodies. As this passive immunity wanes, infants encounter environmental microbes and receive their routine childhood vaccinations. You will address a key gap in this field: despite the critical importance of this early developmental window, surprisingly little is known about how immune cells evolve over time in healthy, term-born infants, or how clinical and demographic factors shape these trajectories. During this crucial phase, you will study how their immune system learns to fight off harmful pathogens while safely establishing a healthy microbiome and maintaining tolerance to beneficial microbes.

As a postdoctoral researcher in this project, you will be involved in the full experimental and analytical workflow. You will:

• Coordinate and oversee the processing of blood samples for single-cell RNA sequencing.
• Perform wet lab single-cell sequencing experiments (FLEX scRNA-seq) together with the laboratory technicians.
• Carry out data analysis of the generated single-cell datasets, including quality control and downstream analyses.
• Interpret the results in close collaboration with immunology and bioinformatics experts and translate findings into biological and public health insights.
• Connect with both technicians and different project leaders, ensuring smooth communication and integration of laboratory work and data analysis.

In this position, you will work with cutting-edge single-cell RNA sequencing technologies in a highly relevant public health setting at RIVM. You will be part of a multidisciplinary team where experimental immunology, advanced omics data analysis and clinical research come together, offering an excellent environment to develop both your wet lab and data science skills.

About the department

You will be based in the Immune Mechanisms – Correlates of Protection (IMC) department of the Centre for Immunology of Infectious Diseases and Vaccines (IIV) at RIVM. The department aims to understand immune mechanisms that protect against disease caused by human pathogens, with a focus on detailed characterization of both innate and adaptive cellular immune responses and the identification of biomarkers and immune profiles that correlate with protection.

Within IMC, you will be embedded in a research group consisting of a principal investigator, PhD students, technicians, a data scientist, and a master student. For this project you will work closely with a second principal investigator, an additional technician and a bioinformatician. You will also have frequent interaction with the clinical study team and the laboratory technicians who process the samples, creating a dynamic environment where laboratory research, data analysis and public health come together.

With us, you’ll find yourself in a friendly, open, and easily approachable work environment. Colleagues connect with each other easily and readily offer support. The atmosphere is informal, with plenty of room for asking questions and sharing ideas. On Mondays, our center is together at the office. That is our fixed day for our team, department-wide and center-wide meetings. This way, you stay well connected to what’s going on in the organization. We often have lunch together and take time for a coffee break. On the other days, you work flexibly in consultation, for example partly from home. We consider a healthy work–life balance important and are happy to think along with you about what works for you. Hybrid working is normal for us, as long as we can find each other on the fixed office day. Choosing us means choosing an engaged team, short lines of communication, and a culture in which you quickly feel at home and are given the space to grow.

Over RIVM

Als Rijksinstituut voor Volksgezondheid en Milieu (RIVM) zijn we een deskundige, betrouwbare en onafhankelijke adviseur voor overheid, professionals en burgers. Ons doel: een gezonde bevolking en een duurzame, veilige en gezonde leefomgeving. We bewaken gezondheid, ziekten, de kwaliteit van de leefomgeving én het milieu. Daarvoor doen we onderzoek en we verzamelen kennis voor toegankelijke informatie en toepasbare adviezen. Het RIVM zorgt voor een goede geboortescreening, het bestrijden van infectieziekten en heeft een centrale rol bij het Rijksvaccinatieprogramma en de bevolkingsonderzoeken. We onderzoeken wat er nodig is voor goede zorg, een gezonde leefstijl, veilige producten en een veilige en gezonde leefomgeving. Ook dragen we bij aan het voorkomen, bestrijden en beheersen van incidenten en crises.

Bijzonderheden

For this position, vaccinations are mandatory as you will be working in laboratories where experiments with pathogens are being performed.
