Research interests

My research focuses on imaging and phenotyping mouse embryos of embryonically lethal KO-lines. Using large numbers of data we define the normal morphology of mouse embryos that have completed organogenesis and use those reference data to identify KO-lines that can be used als model for rare diseases.

A second focus of my research is on peripheral nerves which is mainly conducted on human body donor material. Here we investigate macroscopic topological research questions emerging from clinical practice as well as the the intraneural topology using high-resolution imaging methods.

Techniques, methods & infrastructure

To image embryos, as well as other biological tissues, we use the High Resolution Epicscopic Microscopy (HREM) which generates 3D data in nearly histological resolution.

To answer various research questions we can make use of a well structured body donor facility, which is a powerful resource for maco- and microscopical investigations of the human body.
