I study neural plasticity and memory storage in the adult brain. Our current work revolves around the extracellular matrix structures termed perineuronal nets and how their interplay with the parvalbumin-expressing inhibitory interneurons affect plasticity in the neocortex. To study this we use a range of techniques, including:

Chronic electrophysiological recordings using tetrodes and silicon probes

Optical imaging of intrinsic signals, currently setting up in vivo two-photon imaging

Animal behavior

Immunohistochemistry
