Genetics and molecular mechanisms of axon degeneration diseases (Axonal Charcot-Marie-Tooth neuropathy and Hereditary Spastic Paraplegia)               

To identify the genetic causes of these heterogeneous neurological diseases, we utilize genome-wide next-generation sequencing approaches. We investigate the molecular mechanisms of particular disease mutations by generating patient-specific motor neurons from reprogrammed skin fibroblasts.

Mitochondria in cellular proteostasis, and its tissue-specific consequences

We investigate the consequences of disturbed mitochondrial proteostasis on cell and tissue function, as well as the role of mitochondria in maintaining cellular proteostasis. In relation to human disease, we are particularly interest in mitochondrial aminoacyl-tRNA synthetases that are associated with multiple tissue-specific mitochondrial diseases.

Neurogenomics in routine diagnostics of children and adults: impact on patient care and cost-effectiveness (pHealth Academy Project)

This project aims to evaluate the effectiveness and impact of current personalised genomic technology as the first-line diagnostic tool in progressive neurological diseases of adults and children. This is a collaboration between University of Helsinki, Helsinki University Hospital, and VATT Institute for Economic Research.
