Major Research Interests

Evolutionary pressure has led to the development of remarkably precise and rapid information processing in our central nervous system. Visual and vestibular signals, for example, can be processed with high precision within split seconds. However, most of the underlying cellular mechanisms remain poorly understood.
Our group aims to understand the mechanisms of high-frequency signaling on various levels, ranging from single molecules to neuronal networks. We use cutting-edge electrophysiological, optical, genetic and computational methods, such as direct whole-cell patch-clamp recordings from presynaptic nerve terminals, capacitance measurements and two-photon calcium imaging. We are also driven by the chance that basic neuroscience research will help advance therapeutic possibilities in psychiatry and neurology.
