our GROUP

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

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

​

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

and John Nyakatura's Lab at the HU.

​

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

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.
