Charlotte Teunissen aims to improve care for neurological diseases by studying fluid biomarkers for diagnosis, prognosis and monitoring of treatment responses. Her research addresses the entire spectrum of biomarker development, from identification to assay development, analytical and clinical validation and implementation in clinical practice and trials. Her lab has extensive expertise with state-of-the-art technologies, including ultrasensitive proteomics assays and in vitro diagnostics. She chairs the large biobank of the Amsterdam Dementia cohort, which contains more than 10000 paired CSF and plasma/serum of individuals visiting the Alzheimer Center Amsterdam. She leads the Society for Neurochemistry and routine CSF analysis and the Alzheimer Association-Global Biomarker Standardization Consortium and the Coral proteomics consortium. She is the coordinator of the Marie Curie MIRIADE project, training 15 researchers on innovative strategies to develop dementia biomarkers, and the JPND bPRIDE project, aimed at developing blood-based biomarkers for differential dementia diagnoses.
