Research

Computational and Theoretical Biophysics :

A major research is the function of membrane proteins, e.g. ion channels, in particular, pathways (targeting), membrane integration (translocation), self-organization and transmembrane signaling.

On a mesoscopic level we explored the mechanochemical processes that coordinate neurite guidance, fasciculation and cell migration during development and regeneration of the nervous system.

Corresponding models ranging from the molecular to the coarse-grained description are developed and studied using mathematical methods and computer simulations.

Artur Baumgaertner, born 1946 in Germany, received his doctoral degree in physics from the University of Saarbrucken (Germany) under the supervision of K. Binder. He spent most of his professional career at the Research Centre Julich (FZJ), and he is a member of the faculty of physics at the university of Duisburg-Essen. He is retired from FZJ since 2011.
In 1982 he received an IBM Fellowship for two years and worked at the IBM Research Laboratory Almaden with Do Yoon and with Paul J. Flory (Stanford University) on dense polymer systems. After two years he returned to the FZJ and worked with K. Binder on modeling and simulation of polymers. His research interests at that time was in soft matter including topics as polymers in disordered media, liquid crystal polymers, polymer dynamics, and membranes.
In 1992 he received a Joseph Drown Fellowship from The Scripps Research Institute (La Jolla, USA) where he started to work in the area of molecular and celluar biological physics. In 1996 he established at the FZJ the first group on theoretical biophysics (Forum Modellierung).
The main focus of his work is on function of membrane proteins (bionanomachines) and on the self-organisation of cells (motility, migration, intracellular signaling).
