My main interest lies in testing and diagnosing of rare and special patient samples. For quite some years, I have worked on immunodeficiencies, using both molecular techniques (such as PCR and fluorescent sequencing) and flow cytometry. Nowadays I am part of the Immune Monitoring group as a flow cytometry specialist. Our team tests and analyses patient samples in several research collaborations using advanced flow cytometry based on the EuroFlow Consortium. In between these two jobs, I worked as a graphic designer; making pictures for a study book, presentations and lots of publications. For this I learned how to use Adobe Photoshop and Illustrator. Finally I have also been a member of the TiMaScan team. Within this team I mainly focused on extensive phenotyping of cells from the monocytic and dendritic lineage. The constant progress of the technical possibilities makes this work challenging. It is a constant process of learning and development.



In 1993 I received my certificate from the Hogeschool West-Brabant, being a medical/biochemical technician. I performed my internship at the Erasmus University in Rotterdam on the department of Immunology. My research project was: testing of monoclonal antibodies for the fifth “Leucocyte Typing” conference on several isolated leucocyte subpopulations using fluorescence microscopy and flow cytometry. After my internship I started as a research technician in the same department. I participated in several PhD theses. After a period of working as a graphic designer (2009-2012), still in the same department, I started to work again as a technician on the TiMaScan project. In 2016 our group moved to the LUMC. I continued working on the TiMaScan project and participated in the PERISCOPE project. From 2019 onwards I am a member of the medical immunology team of the Immune Monitoring group.
