About us

The 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.

The Research Group

We are seeking a curious and motivated postdoctoral researcher to join the Cytoskeletal Coordination Laboratory, opening in January 2027 at the Francis Crick Institute. Our lab investigates how molecular machines build, remodel and dismantle the cytoskeleton. We are particularly interested in how these activities are coordinated during cell division, when cells must reorganise their internal architecture and ultimately separate into two daughter cells. We combine biochemistry, structural biology and quantitative microscopy to connect molecular organisation with biological function.

About the role

The successful candidate will investigate how protein machines remodel microtubules. The project will address two linked questions: how these complexes assemble and engage microtubules to couple chemical energy to structural changes, and how interactions with partner proteins regulate their activity. Cryo-electron microscopy will be a major component of the project, alongside reconstitution with purified proteins and fluorescence microscopy. By determining structures of complexes in different functional states and testing the resulting predictions experimentally, you will help explain how molecular interactions drive microtubule remodelling. There will be scope to develop complementary approaches and connect these mechanisms to their functions in cells.

What you will be doing:

• Developing and leading a research project investigating the molecular mechanisms of cytoskeletal remodeling.
• Producing and characterising recombinant proteins and protein complexes, and establishing assays to measure their interactions and activity.
• Using cryo-EM and computational image analysis to investigate the organisation and conformational states of molecular assemblies.
• Integrating structural findings with biochemical and fluorescence microscopy experiments to test mechanistic hypotheses.
• Analysing and documenting experiments rigorously, presenting findings at scientific meetings, and contributing to manuscripts and publications.

About you

You will have:

• A PhD, or a PhD in the final stages of submission, in structural biology, biochemistry, molecular biology, biophysics, or a related discipline.
• Experimental expertise in protein biochemistry and cryo‑EM, including sample preparation and data collection.
• Strong interest in combining these approaches with quantitative fluorescence microscopy.
• Experience designing experiments, applying appropriate statistical analysis, critically interpreting data and troubleshooting research problems.
• Evidence of scientific initiative and the ability to develop and pursue research questions independently.
• Evidence of communicating research clearly through scientific writing and presentations.
• A collaborative approach to research and the ability to work effectively with colleagues.
• Experience in single‑particle image processing and model building.

AI in our recruitment process

We welcome the responsible use of AI as a tool to support your application, but we ask that it is used to enhance your own experience, ideas and achievements, rather than replace them.
