Research Summary: 

Protein function originates from a cooperation of structural rigidity, dynamics at different timescales and allostery. However, how these three pillars of protein function are integrated is still only poorly understood. We are using different molecular techniques to understand how function and activity is created by phosphorylation enzymes, especially kinases and phosphatases.
