About me

I am lecturer in the department of Biodiversity headed by Jens Boenigk at the University of Duisburg-Essen, Germany. As a bioinformatician with a focus on high-throughput sequencing, I support biodiversity research in the field of aquatic biology. This includes metagenome and -transcriptome studies for freshwater habitats, transcriptome and genome assemblies of protist model species (Chrysophyceae) and the assessment of their molecular reactions and responses to environmental parameters and stressors. Before, I have worked as a bioinformatician in the department of Genome Informatics headed by Sven Rahmann at the University Clinics in Essen. Former responsibilities included bioinformatic analyses in the field of human genetics, oncology, medical microbiology and radiation biology, including the detection of structural variants, the analysis of new pathogenic organisms and exome and transcriptome analyses in the field of genetic diseases. During my PhD I worked on methods for integrated network analysis using different *omics datasets in conjunction with biological networks.
