Professor of Mathematics & Discipline Lead

Profile

Gunnar Hornig obtained his PhD in 1997 from the Ruhr-Universität Bochum (RUB), Germany.

He led a junior research group funded by the Volkswagen Stiftung for six years at RUB before he came for a one-year visiting position to the University of St Andrews.

In 2005 he took up a position at the University of Dundee to build up a new group on Magnetohydrodynamics.

Research

His research interests lie in the area of mathematical methods applied to fluid dynamical systems, especially to magnetohydrodynamics (MHD).

MHD is a theory which describes the behaviour of electrically conducting fluids such as plasmas or molten metals and applies for instance to the atmospheres of stars like our Sun. These plasmas show an amazing variety of phenomena of self-organisation and structure formation which are a challenge to understand.

To describe or predict these phenomena we use a wide range of mathematical tools from dynamical systems theory, differential geometry, topology and numerical analysis.
