My research:
My research is focused on viral-bacterial interactions in the sea-surface microlayer, the upper 1 mm layer at the ocean’s surface. Under certain conditions, viruses can become enriched in this thin habitat at the air-sea interface, but the role of microlayer viruses (‘the virioneuston’) for the microbial loop and carbon cycling at the sea surface is largely unknown. To characterize virus-host interactions under enrichment conditions, I use a combinatory approach of cultivation experiments, microscopic and metagenomic analyses to study the virioneuston.
