 Research interests           

 

I am interested in the functional morphology of animals in general. The mechanism I am currently working on is a defensive mechanism that probably evolved three times independently in oribatid mites - ptychoidy. It enables the animals to retract their legs and mouthparts into a secondary cavity in the idiosoma and by deflecting the prodorsum encapsulate themselves. The mechanism is very complex, requiring several exoskeletal and muscular adaptations. And the study of those features in the three groups reveals that every group meets these requirements differently based on their phylogenetic background (for example the accommodation of hemolymph displacement during encapsulation).
