I am researching the co-evolution between viruses and their hosts in the marine environment, and how they structure microbial communities. My research focus is on nucleocytoplasmic large DNA viruses (NCLDVs) and how they interact and coevolve with their phototrophic eukaryotic hosts belonging to Haptophyta. My project will involve cross-infection experiments using a selection of viruses and hosts, looking at the expression and functionality of interesting viral auxiliary metabolic genes that may affect the host energy metabolism and investigating the diversity and distribution of these viruses and hosts in marine communities.
