My work broadly focuses on marine host-microbe systems, or ‘holobionts’, and the metabolic interactions that arise from and drive these complex symbiotic associations. I have always been interested in the microbial functions underlying holobiont health, resilience, and ecological adaptation, and how they shape holobiont stress responses. For this, I mainly use the cnidarian-algae symbiosis and associated bacteria as model systems, but have recently also started exploring the community structure, dynamics, and metabolic properties of fish skin microbiomes. My past and current research includes work on the contribution of nitrogen cycling pathways in cnidarian holobiont functioning and symbiotic breakdown, e.g., coral ‘bleaching’, as well as the elucidation of unknown functions of coral bacterial symbionts. For this, my approach has been to combine traditional physiological and culture-dependent techniques with high throughput-, next generation -omics applications, including whole genome and gene amplicon sequencing, transcriptomics, and proteomics. Currently, I am expanding my scope to targeted investigations of symbiotic metabolic interactions as a driver of osmoregulation in cnidarian holobionts employing nanoscale secondary ion mass spectrometry (NanoSIMS) along with isotopic profiling metabolomics.
