** Seminar and Colloquium Organizer **

Since Fall 2004 (with a break of one year from Fall 2007 until Spring 2008) I am organizing
the *Colloquium* in the Department of Mathematics and Statistics at the University of
South Alabama.

Since Fall 2003
Cornelius Pillen and I (joined by Yorck
Sommerhäuser from Fall 2007 until Spring 2013) are organizing the *Algebra Seminar*
(since Fall 2015 the *Pure Mathematics Seminar*) in the Department of Mathematics
and Statistics at the University of South Alabama.

From Fall 1989 until Summer 1996
Helmut Strade, Peter Slodowy, and I organized the *Algebra Seminar* in the
Department of Mathematics at Hamburg University, Germany. In this time period I also
organized other seminars (alone and jointly with colleagues) on various other topics
as *Fractal Geometry*, *Elliptic Curves*, *Knot Theory*, and *Probability
for Teachers*.
