Research focus

I study the neuronal mechanisms underlying early processing of sensory information. My research approach is centered on striving for a functional understanding of neuronal circuits and representations in the context of efficient coding and evolution. Particularly, I focus on investigating adaptations in neural microcircuits in the auditory system and their computations to optimize the processing of natural stimuli.

Fundamentally, neural plasticity for efficient processing can have very diverse temporal time courses: Adaptations may range from transient effects of activity changes within seconds or even milliseconds to experience-dependent changes of circuit formation during development or the lifetime of an organism. To cover this wide range, I apply and combine a multitude of methods spanning from single cell electrophysiology in combination with pharmacology and behaviour, comparative anatomy of microcircuits and human psychophysics.
