We explore the diversity and evolution of function in biological materials and animal traits. We are especially interested in the origins and evolutionary consequences of superior performance in biological materials, and in the interactive evolution of constructed (extended) phenotypes and body morphologies. In addition, we aim to understand the evolutionary dynamics and functional trade-offs of modified body shapes, such as in ant-mimic spiders, and contribute to the documentation of biodiversity in poorly studied faunas of the world. We are funded by the European Commission - European Research Council and the German Research Foundation.
