David Exposito-Alonso

I am a postdoctoral researcher in the Walsh Lab at Boston Children’s Hospital and Harvard Medical School. My research is focused on the mechanisms regulating brain development and connectivity, and the processes that go awry in neurodevelopmental disorders.

Research interests

I am broadly interested in understanding how neuronal circuits are formed and function; from the molecules involved in the assembly of synapses to the connectivity and physiology of cell types within brain circuits. In particular, I study the molecular and synaptic mechanisms underlying the development of the cerebral cortex, a brain region involved in higher-order cognition.

Ongoing work


What molecular and cellular mechanisms regulate the formation and function of synaptic connections in the cerebral cortex?


What are the developmental and synaptic principles that govern the connectivity of diverse cell types in cortical circuits?


What signaling pathways are affected in neurodevelopmental disorders, and how are they associated with altered cortical connectivity?
