**Salary for this Role:**From £45,500 with benefits, subject to skills and experience.**Job Title:**Postdoctoral Fellow - Cellular signalling and cytoskeletal function lab**Reports to:**Michael Way**Closing Date:**19/Feb/2026 23.59 GMT**Job Description:****Job Title:** Postdoctoral fellow - Cellular signalling and cytoskeletal function - Way lab**Details of the role:****Reports to:** Michael Way – Group Leader**Working pattern:** This is a full-time fixed term position for 4 years on Crick Terms & Conditions of Employment**Application closing date**: 19th of February 2026 at 23.59The Francis Crick Institute is Europe’s largest biomedical research institute under one roof. Our world-class scientists and staff collaborate on vital research to help prevent, diagnose and treat illnesses such as cancer, heart disease, infectious diseases and neurodegenerative conditions.The Crick is a place for collaboration, innovation and exploration across many disciplines. A space where the brightest minds can pursue big and bold ideas and discover answers to crucial scientific questions. We support them in a dynamic environment which fosters excellence with state-of-the-art infrastructure, cutting-edge facilities, and a creative and curious culture. We’ve removed traditional boundaries of departments, divisions and disciplines and instead have an open approach that supports every researcher. This gives us the freedom to take risks and carry out high-quality, pioneering research. Creating a space for discovery without boundaries helps us to turn our science into benefits for human health and the economy.**About the role**We are seeking a talented, highly motivated and independent post-doctoral scientist to work on a project examining the role of molecular motors (myosins and kinesins) and the cytoskeleton (actin, septin and microtubules) during vaccinia virus egress. This work will employ a combination of biochemical, structural and cellular approaches, including advanced live cell imaging and in vitro motility assays. The position is based in Michael Way’s laboratory at the Francis Crick Institute.**The Project**Investigating how viruses use the different cellular machineries and processes of their hosts during replication, assembly and spread offers a unique opportunity to obtain mechanistic insights into the regulation and function of diverse cellular processes. To this end, we use Vaccinia virus as a model together with quantitative imaging and biochemical approaches to study a variety of cellular processes, including regulation and function of the actin and microtubule cytoskeletons, as well as septins.Vaccinia virus is the prototypical member of the poxvirus family, which includes the causative agents of smallpox and mpox. Like all poxviruses, Vaccinia undergoes a complex replication and assembly process in viral factories in the cytoplasm of infected cells (PMID: 36862727). Following assembly, both intracellular mature (IMV) and intracellular enveloped (IEV) virions recruit kinesin-1 to undergo microtubule-based motility from their site of assembly to the plasma membrane (PMID: 36093836).We have a good understanding of how IEV recruit kinesin-1, but the molecular basis for motor recruitment to IMV remains unknown. We also lack an understanding of how virions fuse with the plasma membrane and how the cytoskeleton and associated signalling pathways regulate viral exocytosis. Immediately after virion fusion with the plasma membrane, but prior to the induction of actin polymerization, vaccinia recruits septins and clathrin (PMID: 29921601 and BioRxiv https://doi.org/10.1101/2025.08.20.671218). Septins act as a restriction factor that suppresses viral release from the cell, while clathrin enhances viral spread by promoting actin assembly. The molecular basis for septin recruitment beneath extracellular virions on the plasma membrane remains unknown. It also remains to be established how signalling pathways and cytoskeletal dynamics facilitate the spread of vaccinia virus in a tissue rather than between cells in a tissue culture dish.The focus of the project will depend on the candidates own interests, while aiming to address the questions outlined above, using a combination of biochemical, structural and cellular approaches. These will include advanced live cell imaging and in vitro motility assays to understand the role of molecular motors (kinesins and myosins), as well as microtubules, actin and septins in the assembly and egress of vaccinia virus.**What you will be doing**Postdoctoral Fellows are expected to lead their own projects, contribute to other projects on a collaborative basis (both in the lab and with external collaborators) and guide PhD students in their research. The ability to work in a team is essential.You will:* Perform live cell imaging to track cytoskeletal, motor and viral dynamics in real time.* Perform biochemical and cell based assays to determine how virions interact with kinesins, myosins, septins and other host factors.* Use in vitro motility assays to reconstitute and analyse motor‑driven transport of virions.* Manipulate host cells (e.g., siRNA, CRISPR, inhibitors) to test how specific pathways, motors or cytoskeletal components affect viral movement and egress.* Contribute to other projects on a collaborative basis* Guide PhD students in their research* Lead on projects**About you**You will have:* A PhD in biochemistry, cell or molecular biology \** Good knowledge and experience in signalling and cytoskeleton\** Technical expertise in imaging, cell biology and/or biochemistry \** Track record of writing papers as evidenced by publications or submitted manuscripts* Evidence of data presentation at scientific meetings* Ability to work independently and also capable of interacting within a group* Experience in live cell imaging and image analysis (desirable)\*Minimum Criteria**About Working at the Crick****Our values**Everyone who works at the Crick has a valuable role to play in advancing the Crick’s mission and shaping our culture.* We are **bold**.
