TUM – Technical University of Munich Menü

Prof. Dr. Jörn Kruhl


Tectonics and Material Fabrics
Professor emeritus since October 1, 2014

Academic Career and Research Areas

Prof. Kruhl (b. 1949) researches the microstructure and macrostructure of crystalline materials. He is particularly interested in quantifying the structure of rocks (pattern analysis), material properties and material history, the development of the continental crust and geothermics.

After studying geology at the University of Hamburg, Prof. Kruhl did his doctorate at the University of Bonn in 1978. He completed his lecturer qualification at the University of Mainz (1988). A Feodor Lynen Research Fellowship from the Alexander von Humboldt Foundation enabled him to work at the University of Salzburg from 1985 to 1987. Prof. Kruhl has been a visiting professor at the University of Jordan in Amman and a lecturer and professor at TU Berlin and the University of Frankfurt. He has been a member of TUM’s teaching and research staff since 1996.
