Research interests

Research Interest: Neural Stem Cell biology, cortical development and RNA regulation.
Neural stem cells (NSCs) generate a remarkable diversity of neurons and glial cells during development of the cerebral cortex and defects in progenitor proliferation and differentiation are a major cause of neurodevelopmental disorders such as microcephaly, autism, seizures and intellectual disability. RNA-binding proteins (RBPs) are involved in post-transcriptional regulation and mRNA metabolism and have recently emerged as critical regulators of NSCs during cortical development.
In April 2017, I joined Dr. Debra Silver´s lab where I plan to study the role of RBP in neurogenesis during cortical development and the regulation of RNA and signaling in neural progenitors. I will use multidisciplinary approaches that include In Utero Electroporation, progenitor primary cultures, brain slices, transgenic mice, biochemical assays and transcriptomic/translational profiles.

Background: I am from Argentina and I did my graduate training in Dr. Gustavo Paratcha´s lab in the Institute of Cellular Biology and Neuroscience “Prof. E. De Robertis” (IBCN) in the University of Buenos Aires (UBA – CONICET), Argentina. My PhD thesis focused on the negative regulation of neurotrophic factor receptor signaling in developing neurons.
Personal Interests: In my free time I really enjoy hiking, playing soccer, going out with friends and family, traveling around, reading and watching series and movies.
