Advances in Construction Materials 2007 (eBook)

PrivDoz Dr.-Ing. Christian U. Große, born 1961, studied Geophysics at the University of Karlsruhe (TH) and earned his Ph.D. in 1996 in Civil Engineering at the University of Stuttgart followed by his Habilitation in 2005 at the same place. He is University lecturer (Privatdozent) at the University of Stuttgart and head of the Department of "Non-destructive testing and monitoring techniques" at the Material Testing Institute MPA, University of Stuttgart. Currently, he has published more than 180 scientific papers at international journals and conferences. His research interest include the application and development of non-destructive testing methods (ultrasound, acoustic emission, impact-echo, vibration and modal analysis, Radar, optical methods) as well as structural health monitoring using wireless sensor networks.
