Job Description
Main Purpose of the Job
Postdoctoral Researchers work with limited supervision to carry out individual and collaborative research projects relevant to the overall needs of the research programme. Working as part of a team led by Phil Carella, you will perform key experiments aimed at understanding virulence strategies enabling Pseudomonas viridiflava success in divergent land plants like Marchantia polymorpha and Nicotiana benthamiana. The role will provide you with a broad range of stimulating activities, including:
• Evolutionary and molecular dissection of virulence mechanisms (effectors and toxins)
• Molecular microbiology approaches to genetically manipulate virulence and other key Pseudomonas traits
• Experience with a wide range of plant and microbial techniques including genetics, biochemistry, and computational approaches.
In this role, you will have the opportunity to develop your skills in the emerging field of Evo-MPMI (evolutionary molecular plant-microbe interactions). You will also work with world leading scientists who are experts in their field.
