---------------------------------- Keynote speaker's biography:
Marc Kamlah is head of the Mechanics of Materials I department at the Institute for Materials Research II of Forschungszentrum Karlsruhe, he is also an apl. Prof. at the Faculty of Mechanical Engineering, University of Karlsruhe. Marc received his degree in Engineering Mechanics from Technische Universität Darmstadt. After his PhD in Mechanical Engineering at the University of Kassel, he joined Forschungszentrum Karlsruhe. A major emphasis of his research activities lies on modeling thermo-electro-mechanical field coupling phenomena. A multiscale approach is employed amalgamating phase field modeling, micromechanics, and classical continuum theories. In particular, much work has been done in the field of ferroelectrics.
Marc Kamlah was one of the keynote speakers at the COMSOL User's Conference, fall 2009 in Milan.
