Translational microbiome

Links/websites:

I did my MSc and PhD at the Max Planck Institute for Marine Microbiology in Bremen, Germany. My PhD focused on host-symbiont interaction and metabolism of sulphur-oxidising and methane-oxidising symbionts from deep-sea mussels. I am passionate about host-microbe interactions!

At the Quadram Institute, I am working on sulphate-reducing bacteria that reside in the GI tract of humans and animals and the role they play in the development of inflammatory conditions. I am currently developing molecular genetic tools to identify how the bacterium Bilophila wadsworthia colonises and maintains the association with other members of the gut microbiome. I am also interested in the impact of nitrogen fixation by Desulfovibrio diazotrophicus in the human gut microbiota.
