Research

My previous research work focused on cognition in the context of normal aging and neurodegenerative disorders such as Alzheimer’s Disease (AD), with a focus on a multidimensional and integrative approach, combining cognitive assessments, biomarkers, and neuroimaging data.

Since 2020, I have extended my research into the field of insurance medicine, with a particular emphasis on neurological disorders. My work has primarily focused on identyfing risk factos for, and the consequences of, sickness absence in individuals with multiple sclerosis (MS).
