1.) Unlocking calcium pathways in a changing world

Our climate is changing and so, too, are our oceans, they are warming and becoming more acidic. Marine calcifiers, such as molluscs, are under threat as the ability to extract carbonate ions to incorporate into shell may be compromised as oceanic pH drops and temperatures soar. We are using environmentally and economically relevant species to understand mechanisms of biomineralisation in order to make predictions on how these important calcifiers will fare in a changing world.

2.) Molluscan biomineralization: development, repair and evolution

The slipper snail genus Crepidula is an emerging model system to study developmental questions in the Spiralia. We are using slipper snails as a model to to dissect the molecular and cellular basis of molluscan biomineralisation and repair. By adopting a comparative approach within the Crepidula genus, we will also yield insight on the microevolution of these processes.
