My main research interest is in the field of neurodegenerative disorders. In particular, I have been focused on Amyotrophic Lateral Sclerosis (ALS) which is a progressive and fatal disease due to a specific motor neuron cell death in brain and spinal cord.

Several of the identified genetic factors in ALS are deeply associated to RNA metabolism. A consistent body of evidence suggests that FUS and TDP43, proteins which are mutated in the familial form of ALS, exert important functions in the regulation of alternative splicing, RNA maturation and trafficking. Currently, by using human cell lines and Drosophila melanogaster ALS models, I am studying the molecular mechanisms underlying the pathogenesis of this disease and I am working on the identification of new genes involved in its onset.

My research activities are currently focusing on three main projects:

- the study of a physiological and functional interaction between the mitochondrial protein p32 and ALS-linked mutant form of FUS;

- identification of mRNA downstream FUS-mediated alternative splicing regulation .

- the role of hydrogen sulfide, a signaling molecule involved in several neuronal pathways, in TDP43-dependent stress response.
