After three years of experience in the clinical trial sector, Brian Kruisinga got hired by the Den Boer group in August 2022 as a research technician. The focus of this research group is to study different aspects of the leukemic niche in the context of B-cell precursor acute lymphoblastic leukaemia (B-ALL), including intercellular interactions, gene expression and protein/cytokine expression. Brian works closely with PhD-students to assist them with their projects by performing experiments using flow cytometry, cell-culture and (q)PCR. Besides research topics he is also involved in processing of samples derived from B-ALL patients enrolled in clinical trials.
