Who I am I am professor in numerical analysis at NADA KTH. I took my Ph D in Lund 1970 and have been working  in Umeå 1970-1983, at Chalmers in Göteborg  1983-2001, at KTH Stockholm since 2001. I took retirement 2007. See detailed cv   and BiBTeX archive ! Recent publications   and manuscripts available for download! Research My field is numerical linear algebra with an emphasis on numerical computation of eigenvalues and some detours towards parameter estimation and approximation. Some current activities: Eigenvalues of large sparse matrices .  Reduced order models of large dynamical systems Nonlinear least squares Information Retrieval using matrix algorithms See the detailed description , which also contains some historic material, and the recent monograph Scientific publishing business I am Editor in Chief of BIT Numerical Mathematics since 2003. BIT  homepage , publisher Springer, their BIT Homepage .  BIT was started by my advisor Carl Eric Fröberg in 1960. Its 50 th anniversary was celebrated June 17-20 2010 in Lund. Selected talks are published in BIT 51:1 which is distributed to the participants. Teaching Now I am done with teaching but will come up to KTH occasionaly. Reach me by email!
