Research interests

My general aim is to understand how hippocampal circuits are functionally organized to produce the various forms of coordinated activities that support hippocampal function and dysfunction, including memory, time and space coding, and seizure generation. For the past ten years in my lab, we have been addressing the issue of cortical circuit organization from a developmental perspective since I strongly believe that network development naturally provides a unique environment to dissect how microcircuits are organized. To describe cortical networks at the scale of microcircuits, we had developed a multi-angle experimental approach combining two-photon imaging of network dynamics in vitro (and now also in vivo) with mathematics, electrophysiology and neuroanatomy. I am now at a step where I can start applying the lessons from our previous developmental studies to determine whether a developmental scaffold is supporting the functional organization of adult hippocampal networks.
