Tenure Track Adjunkt
- Nucleic acids sequencing
- Bacteriophage resistance mechanisms
- Phage therapy / biocontrol
- Bacteriophage genome modifications
Our research group, Environmental Microbial Genomics, is focusing on genomic and metagenomic studies in a highly customized manner using in-house, high-throughput and full genome sequencing (Illumina and Nanopore sequencers) of pro- and eukaryotic organisms. The group uses sequence-analysis based information to describe genomic traits of keystone species and their prevalence in natural and artificial microbial communities and metagenomes, including information on bacteriophages and how other mobile genetic elements shape microbial evolution and traits.
My research is focused on viruses of microorganisms, their hosts, microbial ecology and phage-host interactions and alternative bases. I am studying bacteriophages using a cross-disciplinary approach with both classical and molecular methods.
