Research Interests

My research focuses on the evolution of small RNAi systems especially the fast evolving and in part enigmatic Piwi-interacting (pi-) RNA- and small-interfering (si-) RNA-pathways. These small guiding RNAs play a crucial role in the control of mobile DNA during germ cell development and rapidly co-evolve with their targets resulting in lineage-specific realizations. We want to figure out evolutionary adaptations on the genomic and transcriptomic level that ensure the maintenance of a functional transposon defense over time. In addition, we are interested in elucidating the factors that trigger prima facie functionally redundant siRNA- and piRNA-pathway utilization. Finally, facing the fact that only a minority of mammalian piRNAs target transposons, we attempt to broaden our understanding of piRNA function beyond transposon control.

Key techniques: sRNA sequencing, bioinformatics

Research system/organism: Mammals (esp. primates) incl. non-model species
