Research projects

 

The major research goal in our laboratory is to understand the molecular and cellular mechanisms underlying the development and evolution of the cerebral cortex, from stem cells to neuronal circuits, from mouse to man, in health and disease. 

The cerebral cortex is one of the most complex and important structures in our brain. In correlation with its elaborate functions, it is made of dozens of distinct types of neurons that display specific patterns of gene expression and synaptic connectivity. Moreover the cortex underwent a major increase in size and complexity during recent hominid evolution, mostly related to increased neuronal number and connectivity.

How does cortical complexity emerge during human development, and how did it increase during evolution? What is specific to human brain development and how does it relate to brain diseases?

We try to address these fascinating questions using an integrated approach that combines tools of human pluripotent stem cell technology, mouse developmental neurobiology, and mouse brain xenotransplantation.

We also apply the same techniques for the modeling of human neurodevelopmental diseases, and to explore the possibility of rational design of brain repair strategies through cell transplantation.
