As a member of the CCG’s bioinformatics team, my work focuses on the continuous operation and maintenance of the CCG’s NGS analysis pipelines for monogenic disease research. Here, the optimization of the workflows for robust and efficient operation in the HPC environment provided by the Regional Computing Center of the University of Cologne (RRZK) is the main goal. Additionally, I do custom analyses of smallRNA sequencing experiments and CNV analyses in exome or genepanel cohorts. Analysis results can be comfortably accessed and reviewed through the CCG’s Varbank database and webinterface continuously advanced by the CCG’s bioinformatics team (

The CCG’s exome analysis pipeline.
