Academic Career and Research Areas

Prof. van Hemmen’s (b. 1947) research explores cellular theoretical biophysics. He is interested in both theoretical membrane physics and neural information processing of various sensory organs. He investigates mechanosensing – the sonic ranging of the barn owl, the location of aquatic objects through the lateral-line organs of the clawed frog and fish, infrared vision in certain snakes and their multimodal integration.

Prof. van Hemmen studied physics and mathematics at the University of Groningen (NL), and completed his doctorate there in 1976. Following a year of postdoctoral research at the Institut des Hautes Etudes Scientifiques (IHES) in Bures-sur-Yvette near Paris, he spent a further year as assistant professor at Duke University (Durham, NC). After that, he joined Collaborative Research Center 123 (Stochastic Mathematical Models) in Heidelberg, where he qualified as a physics lecturer in 1983. Prof. van Hemmen has been lecturing in cellular theoretical biophysics, in particular neuronal information processing, at TUM since 1990. He is a fellow of the American Physical Society.
