Academic interests

I am working in a research group headed by Prof. Anders M. Fjell and Prof. Kristine B. Walhovd. We strive to understand the complex and dynamic relationship between alterations in the brains structural make-up and its functional manifestations in normal development and aging, as well as following discontinuity in the normal development trajectories due to for instance disease. To this end, we use magnetic resonance imaging (MRI), including diffusion tensor imaging, electroencephalography/event-related potentials, and various cognitive-behavioural tasks. Our current and planned research projects also include genetic data in order to investigate the influence of genetic variance on cognitive and brain-based phenotypes.
