Biomarker development


Biological markers (i.e. biomarkers) are necessary to translate mechanistic studies in rodents to human settings, and for monitoring risk and progression of disease in live subjects. Examples of studies performed in our group include testing the potential of gene expression to predict non-remission in depression prior to antidepressant treatment initiation, of proteomic, structural and imaging data to predict cognitive impairment in late-life depression, and of integrated genetic scores to predict higher risk for having depression in later life.
