System Administrator (m/f/d)

caesar is a neuroethology institute located in Bonn that studies how the collective activity of the vast numbers of interconnected neurons in the brain gives rise to the plethora of animal behaviors. Our research spans a large range of scales from the nano-scale imaging of brain circuitry, to large-scale functional imaging of brain circuitry during behavior, to the quantification of natural animal behaviors. caesar is closely associated with the Max Planck Society and shares its scientific principles.
