Benjamin B. Tournier is a research scientist employed in the Department of Psychiatry (University Hospitals of Geneva, HUG) and Privat docent at the Faculty of Medicine (Department of Psychiatry, University of Geneva – Unige). His areas of expertise include in vivo imaging, animal behavior measurements, mRNA and protein quantification and the use of methodological approaches (stereotaxic, AAV-mediated synthesis of recombinant protein…) for the study of neuroinflammation in Alzheimer's disease.
