### Mini CV

I studied mathematics and physics in the
School of Mathematics and Physics
of the
Albert-Ludwigs-Universität Freiburg. Then
I continued in the Section of Mathematical Logic of the Institute of Mathematics, where I received my Ph.D.

Then I became an assistant at the University
of Bonn, the Rheinische Friedrich-Wilhelms-Universität Bonn. I was a member of the Logic Group in the Mathematical Institute of the University of Bonn. I finished my habilitation in 1998 in Bonn.

From January 1995 to December 1996 I worked
at the Mathematics Department of the The University of Michigan in Ann Arbor, Michigan, holding a fellowship from the Deutsche Forschungsgemeinschaft.

From April 1999 to March 2001 I was a Minerva fellow at the Institute of Mathematics of the Hebrew University in Jerusalem working together with
Saharon Shelah.

From April 2001 to August 2009 I was
affiliated with
the
Kurt
Gödel Research Center for Mathematical Logic of the
University of Vienna
in various positions.

From September 2009 until September 2010 I was a Marie Curie Fellow at
the Hebrew
University in Jerusalem.

Now I am a professor of mathematics at the University of
Freiburg in
Germany.
