Understanding the deformation spaces of geometric structures

Funded by the ERC, Prof. Anna Wienhard studies several new geometric forms that have been discovered over the past 20 years. These structures are closely related to the generalisation of Teichmüller space, which describes how the surface of a pretzel can be endowed with the geometry of an Escher painting.

Sponge enzymes: nature’s little bio-builders

Sponges seem an unlikely source for innovation, yet they may hold the key to new nanotechnologies, innovative optical devices and new ways of regrowing human bone and preventing bone disease. Difficult to believe? Not for Werner E.G. Müller. In the BIOSILICA project, he and his team are developing ways to adapt the complex processes that natural glassy sponges use to build their wondrous biosilica structures for use in biodegradable implants that would facilitate bone healing after surgery or fractures.
