Karl Martin Wolf (born 1961) is a German experimental physicist specializing in electron and optical spectroscopy and their use for studying the dynamical processes in solid state materials, surfaces, and interfaces.
He is the current director of the Department of Physical Chemistry at the Fritz Haber Institute of the Max Planck Society in Berlin, Germany.
After completing his PhD, he spent a year as a postdoc at the University of Texas at Austin in the group of Mike White before returning to the Fritz Haber Institute as a member of the research staff in 1992.
He has held this position for about a decade, and in 2008 he was appointed as the director of the Department of Physical Chemistry at the Fritz Haber Institute as a successor of the Nobel laureate Gerhard Ertl.
In 1992, he received the Reimar Lüst Stipend from the Max Planck Society, and in 1993 he was awarded a research fellowship from the Arthur von Gwinner Foundation.
