Job Description

The Odendall Laboratory studies both sides of interactions between the host and enteric bacterial pathogens. We seek to understand the interplay between the bacteria Salmonella and Shigella and type I and III interferons (IFNs).

Type I and III IFNs are induced, along with other cytokines, upon detection of microbes. They have a direct effect on the tissue, inducing hundreds of interferon-stimulated genes (ISGs), with diverse antimicrobial functions. While the functions of type I/III IFNs in antiviral immunity are extensively studied, if/how IFNs and their ISGs protect against bacterial infection is poorly understood.

We have recently reported that bacterial factors translocated by the Shigella type III secretion system (T3SS) block IFN receptor signalling (Alphonse et al, Cell, 2022), and the induction of ISGs. This suggests the importance of this pathway in host defence against bacteria. Indeed, IFNs were protective against Shigella infection in cellular and animal models of infection.

Similarly, we have found that IFN restricted intracellular infection with Salmonella, an enteric pathogen with similarities to Shigella. This MRC-funded project will investigate the functions of type I/III IFNs and a few key ISGs in mouse models of Salmonella infection.

Mice lacking IFN receptors will be infected with different strains of Salmonella. Salmonella pathogenesis and the immune response to infection will be investigated, including histopathological scoring, and gene expression studies.

The successful candidate will have a PhD in immunology, be hardworking, with a proven track record of publication as a primary author of scientific paper(s) in well-regarded scientific journals. They should have a particular interest in tackling fundamental questions regarding host-pathogen interactions.

This post will be offered on an a fixed-term contract until February 2026.

This is a full-time  post.

Key responsibilities

  • Develop a cutting-edge research project aiming to identify the functions of type I and III IFNs in mouse models of Salmonella enterocolitis 
  • Work semi-independently and collaboratively to develop knowledge of the literature in the subject area; design and control experiments for the above project; maintain accurate records of performed experiments and conclusions in line with the group’s expected standards; and meet agreed upon deadlines.
  • Communicate research findings via drafting of publications arising from this work; and preparation and delivery of presentations about relevant research findings within the team and within and outside of the Department.
  • Handle laboratory equipment safely and considerately, assist with general laboratory upkeep, report safety issues instantaneously, and comply with the requirements of the Health and Safety regulations.
  • Contribute to the day-to-day training and supervision of junior staff and undergraduate and/or graduate students within the Team (as appropriate) 
  • Initiate purchase of consumable items and minor equipment within budgetary limits and in consultation with the PI. 
  • Positively support equality of opportunity and equity of treatment to colleagues and students in accordance with the College Equal Opportunities policy 

The above list of responsibilities may not be exhaustive, and the post holder will be required to undertake such tasks and responsibilities as may reasonably be expected within the scope and grading of the post.
