Research

My previous research work focused on Normal Aging and Neurodegenerative disorders such as Alzheimer’s Disease (AD), with a focus on the multidimensional and integrative study of cognitive, clinical, socio-demographic, and neuroimaging factors.

Since 2020 I have extended my research to the field of insurance medicine, focusing on risk factors for and consequences of sickness absence in relation to multiple sclerosis (MS).
