Major Research Interests:

Our lab is interested in functional principles of neuronal circuits. We employ modern optical methods, including two-photon microscopy, allowing for activity imaging with high penetration depth and single cell resolution in living tissue. The main focus of our work is studying neuronal ensembles in the mouse auditory neocortex. Of particular interest are the effects of developmental aberrances in the auditory brainstem on the computation of the auditory cortex. We are also involved in the development of new analysis tools to decipher patterns in the complex data sets obtained by activity imaging.  research pages
