In general, my research interest lies in the field of marine microbial ecology. And the analysis of prokaryotic diversity patterns within and between phylogenetically divergent marine sponges was my main focus over the last years. Marine sponges are acknowledged holobiont systems with a unique set of features, from being a source of unique secondary metabolites to complex symbiotic prokaryotic communities. Sponge-associated community compositions are influenced by host species over large spatial and temporal scales. Moreover, almost all sponge-species can be grouped into either high or low microbial abundance (i.e., HMA / LMA) sponges based on the abundance of prokaryotic cells in the sponge tissue. It is fascinating how sponge-prokaryotic communities can maintain these distinct diversity patterns at multiple scales (e.g., host-identity & microbial abundance status) over time and location and despite changes in environmental conditions.

In addition, the ongoing improvement and development of molecular tools to describe the composition, functional roles, and interactions of microbial communities in marine holobionts is something that I follow with high interest since I started working in this field. It is intriguing what has changed in our understanding of complex host-symbiont relationships with each new generation of sequencing technology.
