Research Interests

Current projects

 

Methodological expertise

Light microscopy (LM)
Scanning electron microscopy (SEM)
Transmission electron microscopy (TEM)
Serial sectioning transmission electron microscopy (ssTEM)
MicroCT
Ultramicrotomy, including serial-sectioning and resectioning techniques
3D reconstruction (ssTEM, LM, MicroCT data)
microwave assisted chemical fixation

 

Software expertise

Due to the time and labour intensive work of segmenting larger TEM Data sets, I developed a strong interest in automatization, scripting and building time efficient workflow pipelines for my work in the last years. For that purpose mainly open source software (Fiji, ICY, MIB,IlastikBlender, R…) is used. See also here.
