Profile Headshot


I grew up in the beautiful city of Palermo, in southern Italy. I used to spend hours exploring the countryside and observing animal life. I was curious about everything then, and I still am.

During my doctoral studies at the TIGEM in Italy, in the lab of Sandro Banfi, my first publication was in the microRNA field. MicroRNAs (miRNAs) are small molecules that regulate the function of most human genes; the challenge has been to identify each miRNA’s set of target genes. Various bioinformatic methods had been tried, but each approach reveals a different set of targets for a given microRNA. I took a different tack: I hypothesized that the target genes of a given miRNA are likely to belong to the same biological pathway and therefore to be co-expressed. This basic idea led me to develop HOCTAR (Genome Research, 2009) and then the more refined CoMeTa (Genome Research, 2012), whose prediction accuracy reaches nearly 100%, as calculated by analysis of previously characterized human miRNAs. CoMeTa was the first tool to infer the biological pathways of each human miRNA based on the identification of its set of target genes. HOCTAR led to the discovery of the function of miR-128, which controls the master gene TFEB (Science, 2009).

For my postdoctoral work I wanted to bring my background in bioinformatics and RNA biology to bear on problems in neuroscience, so I joined the lab of Huda Zoghbi. I studied the regulation of the epigenetic factor MECP2 during neurodevelopment (Genes & Development, 2013), the post-translational modification of a neurodegenerative disease protein, Ataxin1 (Cell, 2015 and Cell, 2018), and alternative polyadenylation (eLife, 2015). This work forms the basis of my lab’s current projects.

My lab’s overall goal is to understand the molecular mechanisms driving neurological diseases, including isolated neuropsychiatric features, in the hope of ultimately devising viable therapies

Neuroscience made enormous strides during the 1990’s with the advent of molecular genetic techniques that allowed us to identify myriad disease genes and manipulate them in animal models from flies to mice. In the 2000’s, we came to appreciate the importance of epigenetic mechanisms to neurobiology, and now we are on the cusp of a new field that might be called “RNA neurobiology.”

RNA biology may, in fact, have particular importance in the brain, given the extremely dynamic nature of neuronal synapses. The post-synaptic compartment contains polysomes, which indicates that translation is crucial for higher-order brain activity, and protein synthesis has long been thought to be required for memory consolidation. Small wonder, then, that disruption of RNA-binding proteins is associated with wide-ranging syndromes that affect motor control, behavior, and cognition.

My interest in RNA-binding proteins centers on their role in post-transcriptional regulation of proteins that, when mutated, lead to human neurological disease. But my interest is in the wild-type versions of these proteins: my research has shown that relatively modest increases or decreases in the levels of at least some ‘normal’ proteins can be pathogenic. This opens up an entirely new avenue to discovering new neurological disease genes, as I showed recently in the identification of patients bearing mutations in Pumilio1 (Cell, 2018).

Research Interests

  • Developing RNA therapeutic approaches to neurological diseases
  • Establishment and maintenance of RNA homeostasis in the brain
  • Protein dosage and neurological disorders
  • RNA-binding proteins and non-coding RNA regulatory networks in neurological disorders
