Identification and functional analysis of disease-related mechanisms involved in spinocerebellar ataxia1 and motoneuron disease

The main focus of our research is to identify cellular mechanisms causally involved with onset and spreading of neurodegenerative diseases (ND). We use imaging and biochemical techniques combined with systems biology to identify and investigate disease-related aberrant cellular mechanisms.
