Alireza Salami is currently a group leader at Wallenberg Center for Molecular Medicine (WCMM) and a Senior Researcher at the Aging Research Center (ARC). He completed his PhD in computational neuroscience in 2012 at Umeå University where he implemented various multivariate and multimodal techniques to address questions related to structural and functional brain changes in normal aging.

Alireza’s primary research interest concentrates on the brain basis of cognitive decline in old age. It is critical to find measurement tools that can predict future severe cognitive decline, such as the one typically observed in demented elderly people, as early as possible, before substantial irreversible damage has been caused to the brain. Alireza’s group uses advanced functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) in order to explore the functional and molecular bases of cognitive decline in aging.  The group is currently heavily involved in data collection of a large-scale population-based study (DYNAMIC) in which 180 individuals (20-80 years old) undergo extensive cognitive test battery as well as fMRI scanning along with dopamine D1 assessment with SCH23390 and PET.
