Hans J. Herrmann

Hans J. Herrmann received his diploma in physics in 1978 at Cologne University where he also received his PhD in 1981. From 1981 to 1982 he was post-doc fellow at Athens University and from 1982 to 1990 he worked at the nuclear research centres C.T.E and C.N.R.S. at Saclay. From 1990 to 1994 he was director of Many Particle Group at HLRZ Jülich. From 1994 to 2000 he had a chaire de la Matière Diviseé at E.S.PC.I. After that he was Professor at Stuttgart University from 1995 to 2006 as director of the Institute for Computational Physics. Since 2006 he is Professor for Computational Physics for Engineering Materials and since 2007 director of the Institute for Building Materials at ETH Zurich. He is also member of the Departamento de Fisica at Universidade Federal do Cerea in Fortaleza, Brazil. Presently he is working mainly on dunes and Apollonian packings. He is also investigating density waves, fragmentation, stratification, segregation, compactification, sedimentation, dissipative gases, the shape of a sand pile, the dip under the heap, non-linear elasticity of packings and shear bands which he also studies micromechanically.
