Holger G Krapp obtained his Diploma in Biology (Neurobiology) from the University of Tübingen, Germany,  in 1992. In 1995 he was awarded the Dr rer nat (PhD) degree for studying the neuronal mechanisms of optic flow processing at the Max-Planck Institute for Biological Cybernetics, Tübingen, Germany. During his first postdoctoral position at the Max-Planck Institute for Biological Cybernetics he continued working on theoretical aspects and the neuronal basis of self-motion estimation. In 1996 he became postdoctoral scholar at the California Institute of Technology, Pasadena, USA, working on the biophysical mechanism of neuronal multiplication in the context of visually guided behaviour. From 1997 he spent three years as a research fellow at Bielefeld University, Germany, continuing his work on adaptations to optic flow processing in the visual system. In 2000 he commenced a position as a temporary lecturer in Sensory Neuroscience in the Department of Zoology, University of Cambridge, UK, investigating fundamental principles underlying the sensory control of behaviour. He was appointed as a senior lecturer in the Department of Bioengineering at Imperial College in October 2005.
