Research interests

My main focus is on molecular microbiology, bacterial genetics as well as the biology and dynamics of mobile genetic elements, such as plasmids and bacteriophages (short; phages). In particular, I find it quite fascinating to learn more about how plasmids and phages interact with each other as well as with their bacterial hosts. A key element of this research involves the finding and characterization of novel molecular mechanisms underlying this complex, but highly exciting, network of defense and anti-defense interactions/strategies taking place between phages and their bacterial hosts. Phage epigenomics (i.e. detection of nucleotide modifications on phage genomes), as studied by long-read sequencing, has recently been integrated into this research.

In addition, I have a keen interest in isolating and characterizing novel phages from natural environments, in particular from the phyllosphere of wheat plants, a complex and highly diverse plant surface. Adding to our current understanding of how phages interact with- and impact on the microbial communities inhabiting this environment might help us to explore their potential as future biocontrol agents. 

Previously, I have been engaged in finding novel strategies to limit the occurrence of plasmid-borne spread of antimicrobial resistance mediated through horizontal gene transfer. Additionally, I have been engaged in elucidating some of the molecular mechanisms that regulate initiation of bacterial chromosome replication using Escherichia coli as model organism. In particular, adding a more bacterial stress survival/response angle in the sense of bacterial persistence was of interest.
