Job Description
Main Purpose of the Job
A new research group led by Dr Lizbeth Sayavedra is being established at the Quadram Institute to investigate how microbial sulfur and nitrogen metabolism influence human health, particularly in the context of protein malnutrition and obesity.
The group will focus on sulphate and sulphite reducing bacteria, a key family of gut bacteria involved in sulfur and nitrogen cycling, and their interactions with the host and the wider gut microbiome. This position offers the opportunity to contribute to building a dynamic team at the interface of microbial physiology, metabolism, and host–microbe interactions.
This is an exciting opportunity for a motivated microbiologist to bridge in vitro microbiome models and in vivo systems, using functional assays, molecular biology, and bioinformatics to uncover how key members of the Desulfovibrionaceae influence metabolic outcomes.
We’re looking for someone with a PhD in microbiology or a related field, ideally with experience in molecular microbiology, microbial genomics, or microbiome analysis. Experience with bioinformatics or animal models would be a great advantage.
The post holder will work at the intersection of microbiology, molecular biology, and microbiome science to explore how sulfur- and nitrogen-transforming bacteria contribute to metabolic health outcomes. Key responsibilities include:
• Performing anaerobic culturing of gut bacteria, particularly within the Desulfovibrionaceae.
• Conducting gut model experiments to study microbiome–host interactions under different dietary conditions.
• Applying genetic engineering and functional genomics approaches to investigate key metabolic pathways.
• Performing microbiome sequencing and bioinformatics analyses to link microbial activity with metabolic phenotypes.
• Collaborating with internal and external partners within the Food, Microbiome and Health programme, and contributing to publications, presentations, and future grant proposals.
Key Relationships
The post holder will work closely with researchers within the Sayavedra Group and coordinate studies with internal and external collaborators, including the Narbad and Beraza groups, other human microbiome research teams and clinicians at the Norfolk and Norwich University Hospital, such as Dr Emma Webb.
