Forschungsinteressen

Ich interessiere mich für alle Aspekte der COMPUTERALGEBRA,
den Entwurf, die Implementierung und die Anwendung algebraischer
Algorithmen, wobei die ALGEBRAISCHE GEOMETRIE bei den Anwendungen
im Vordergrund steht. Mein besonderes Augenmerk gilt der ENTWICKLUNG
GROSSER COMPUTERALGEBRASYSTEME.

Dekan

Ich war von Februar 2014 bis März 2020 Dekan des Fachbereichs Mathematik.

Aktuelle Lehrveranstaltungen

Zusammen mit Gerhard Pfister biete ich regelmässig In der vorlesungsfreien Zeit Kurse am African Institute for Mathematical Sciences in Kapstadt an.

Curriculum Vitae
