our GROUP

Our workgroup is based at the Max Planck Institute Department of Biomaterials @

the Max Planck Institute of Colloids & Interfaces in Potsdam, Germany 

We have ongoing projects with a variety of regular collaborators, at the Wyss Institute for Bioinspired Design at Harvard, the Zuse Institute for Information Technology in Berlin and other institutions

 

In 2019, we begin collaboration with the Matters of Activity Research Excellence Cluster

our WORK

We investigate principles of organization and performance in animal musculoskeletal systems —particularly in fishes— to address questions relevant to ecology, evolution, physiology and behavior, also incorporating engineering and physical science perspectives to inform biomaterials and translational science.
