Research interests

I am a neuroethologist interested in sensory information processing and its direct impact on behavior.

About

I am a neuroscientist in the fields of behavioral neuroscience and neuroethology. I am interested in primary sensory processing and how it directly controls 'automated' and 'reflex-like' behaviors. The brain optimizes such processes via control of the sensory input by active sensing mechanisms as well as modulation of neuronal mechanisms via plasticity (experience) and neuromodulation (brain state). As a doctoral student I studied the processing of optic flow for depth perception in zebra finches. I first established that zebra finches use a gaze strategy that facilitate depth perception from the optic flow. Then I presented naturalistic motion stimuli during extracellular recording in the motion processing nucleus rotundus. As a postdoctoral fellow I am investigating how experience alters sensory processing. In mice, odor learning (e.g. in social context) is induced by noradrenaline and leads to plastic changes in the first stage of olfactory processing, the olfactory bulb. Noradrenaline, in turn, is believed to be part of the mechanism that generates arousal. By stimulating the main noradrenaline releasing nucleus (locus coeruleus) I mimicked arousal in anaesthetized animals while I presented odors. This lead to plastic changes in the olfactory bulb. Surprisingly the observed suppression of odor responses after noradrenalin release was stronger when no odor was presented during an epoch of locus coeruleus stimulation than when odors were presented simultaneous with locus coeruleus stimulations. I currently study the activation of locus coeruleus in courting male mice and the role of noradrenalin in social engagement. Education: I studied biology and majored in neuroscience for my Diplom degree at the University of Cologne (Germany) in 2006. I then started my doctoral studies at Bielefeld University (Germany) with Prof. Hans-Joachim Bischof where I graduated in 2010 (Dr. rer. nat.). Since then I am a Postdoctoral Fellow at Cold Spring Harbor Laboratory (NY, USA), working with Assistant Professor Stephen Shea.
