David Exposito-Alonso

I am a postdoctoral researcher in the Walsh Lab at Boston Children’s Hospital and Harvard Medical School. My work is focused on investigating mechanisms of human brain development and connectivity and the functional impact of genetic mutations associated with neurodevelopmental disorders. The ultimate goal is to better understand the developmental trajectories of brain disorders to provide new insights into the development of effective therapies.


I am interested in understanding how cellular networks are formed and function in the human brain. Specifically, I investigate genetic mechanisms regulating the development and maturation of the cerebral cortex, a brain region involved in higher-order cognitive function, and how cortical circuits have changed as a result of evolutionary genomic changes.

Ongoing work

Brain Development and Wiring

What molecular and cellular mechanisms regulate the formation of cortical circuits during brain development?

Evolution of the Cerebral Cortex

How have genetic changes in the human genome remodeled the organization of circuits in the cerebral cortex during evolution?

Neurodevelopmental Disorders

Which signaling pathways are impaired in neurodevelopmental disorders? How (and when) the developmental trajectories of the brain are affected by genetic mutations?
