Structural information on biological shapes can be obtained via a number of experimental techniques, including X-ray crystallography, NMR, and cryo-electron microscopy tomography for molecular systems, and multiple microscopy and scanning techniques for larger biological shapes, to name only a few. However, it is the geometric and topological modeling that interprets and translates the data generated by those techniques into a meaningful model of the structure-function relationship for those systems, allowing the geometric information to be integrated into physical models that shed new light on the mechanisms of life. The objective of this workshop is to stimulate interactions between the biologists that collect those data and the mathematicians that provide the geometric and topological modeling. Its program is designed to encourage biologists to outline problems and challenges in data collection and analysis, and mathematicians to describe new creative and efficient solutions to those challenges. The topics of the workshop are as follows:
  • Geometry and topology of bio-molecule
  • Dynamics of bio-molecular shapes
  • Cell topology, geometry, and mechanics
  • Geometry in neurosciences
  • Morphometrics and phylogeny
