CBSB06:
From Computational Biophysics to Systems Biology

June 6 - 9 2006, Jülich, Germany

CBSB06

Scope

Over the last few decades the scope of biology has changed from categorizing experimental observations to understanding the underlying mechanisms. This is at least in part due to the increasing use of computers. Computers allow us to study single macromolecules, the interaction between various biomolecules, or their regulation in the cell. For many medical and pharmaceutical applications such as the understanding of desease pathways or the working of drugs at the level of an individual cell one would like an integration of these simulations - situated at a molecular level - into a functioning model of cells. This is one of the big challenges in computational biology requiring both new hardware and new techniques.

The many benefits of such an extension of computational biophysics into systems biology motivated the workshop that the research group "Computational Biology and Biophysics" held June 6-9, 2006 at the John von Neumann Institute for Computing in Jülich, Germany. Specifically, the workshop targeted the following general areas at the interface between (computational) biophysics and systems biology:

  • Protein folding (both structure prediction and mechanics)
  • Mis-folding and aggregation
  • Interaction between proteins and other molecules
  • Assembly of nano-structures, multi-protein, protein-DNA/RNA complexes
  • Cellular systems at the molecular level
