I am a postdoctoral researcher since August-2014 in our research group. I am interested in combining different approaches including electrophysiology, behavior and pharmacogenetics to tackle some of the challenging and exciting questions in stress- and fear-related research field. Specifically, my current project deals with the state-dependent role of parvalbumin-positive interneurons in fear memory (re)-consolidation in relation to network activity modulation in the ventral hippocampus.
