IJsbrand Reyneveld



I started my laboratory career at the ROC Friesland College in Leeuwarden, where I was educated as a medical laboratory technician in clinical chemistry & hematology. For my first research project, which I performed at Noordwest Ziekenhuisgroep Alkmaar under the supervision of dr. Roger Schindhelm and dr. Marianne Schoorl, I validated an Ektacytometer, which is currently in use as a routine diagnostic tool for erythrocyte membrane disorders.

In 2013, I joined a fast track Bachelor program at NHL Stenden University of Applied Scienced to dive deeper in diagnostics, but became fascinated by the complexity of the immune system and research instead. At the University Medical Center Groningen (UMCG), I interned at the Department of Obstetrics & Gynecology under supervision of prof. Dr. Hans Nijman and dr. Marco de Bruyn, where I studied Myeloid Derived Supressor Cells (MDSC) and T-cells in the context of ovarian carcinoma.

To further grow in the immunology field, I went to the Free University Amsterdam (VU) to study Biomedical Sciences in 2016 with a research specialization in Immunology. My first internship was at Amsterdam University Medical Center (then VUmc) under supervision of prof. dr. Marjolein van Egmond and dr. Melissa van Gool at the department of Molecular Cell Biology & Immunology. Here I studied pro-inflammatory serum IgA in the context of infection. My second internship was at Utrecht University’s Faculty of Veterinary Medicine at the department of Infectious Diseases & Immunology. Under the supervision of dr. Christine Jansen and dr. Aad Hoek, I investigated NK-cells in milk of mastitis affected cattle. For my MSc thesis, I went to the department of Animals Sciences of Wageningen University & Research (WUR), and focused on Natural Antibodies and the opportunities of their modulation in veterinary species under supervision of dr. ir. Henk Parmentier.

Cytometry was the dominant technology during my internships, so I joined the Flow cytometry Core Facility (FCF) at Leiden University Medical Center (LUMC) in 2020 and gained three years of fulltime cytometry experience.

I was further involved in education, quality control procedures and standardization of the facility, became a recognized center of excellence by the International Society for the Advancement of Cytometry (ISAC).

To reconnect with immunology and discover other state-of-the-art technologies in the field, I joined the lab of dr. Vincent van Unen at the Department of Immunology of LUMC in 2023 as a PhD Candidate where I aim to identify drivers of inflammation in chronic inflammatory diseases of the intestine.
