Short Biography

I am interested in the molecular machinery that underlies synaptic structure and function and that enables synaptic plasticity and remodeling.
During my thesis work, I investigated the synaptic scaffold protein MPP2 of the family of membrane-associated guanylate cyclases (MAGUKs) and its function at the periphery of the postsynaptic density of excitatory synapses where it interacts with several proteins mainly associated with inhibitory signalling.

In my postdoctoral training in the Nedivi lab, I will investigate the molecular composition of inhibitory synapses depending on their positioning, afferents and dynamic history. I hope to contribute to our understanding of how the heterogeneity in the synaptic protein framework affects synapse maturation and plasticity.
