Previous Work

My general scientific interests are on the development and function of the neocortical networks. In particular, I am very interested in how the diverse populations of GABAergic interneurons, generated in the ventral subpallium, acquire their position in the neocortex and incorporate into cortical circuitry. Currently, I am using viral tracing and optogenetic methods to examine the dynamic changes in the connectivity of interneurons during postnatal development. These approaches allow us to dissect the identity and synaptic dynamics of the afferents and efferents of early-born interneurons (for example somatostatin expressing-martinotti cells), and elucidate theirroles in early forms of cortical activity.
