Description

My research aims to identify the roles of microbes in chemical turnover processes in aquatic ecosystems and investigate which adaptations make microbes successful in their environment.

My current research investigates the ecology of a group of highly abundant freshwater actinobacteria: Ca. Nanopelagicales (also known as acI clade). These microbes are among the most abundant bacteria in freshwater lakes around the globe. They are of small size (cell volumes <0.1 μm3) and have highly streamlined genomes (<1.5 Mbp). Using a Ca. Nanopelagicales strain collection, I am examining niche separation between strains; their interaction with grazer, phages, and sympatric bacteria; and the role of photoheterotrophy in these bacteria. Besides cultivation and cultivation-based experiments, I am using comparative genomics, single-cell techniques such as CARD-FISH and metagenomic analyses to advance our understanding of the ecology of this group.
