Job description

Research Technician – Cryo-EM / Structural Biology LMS2961
£37,476 - £39,470 per annum, inclusive of London Allowance
12-month Fixed term | Full time | Location: Hammersmith London

Overall purpose:

We are looking for a talented structural biologist to join the DNA Motors group headed by Professor Luis Aragon at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London, working on a translational cryo-EM project.

The DNA Motors group studies the Structural Maintenance of Chromosomes (SMC) complexes – cohesin, condensin and SMC5/6 – using cryo-EM, single-molecule biophysics, biochemical reconstitution and cell biology. Through the LMS–Imperial Drug Discovery Hub, we are running a drug discovery programme targeting the cohesin subunit STAG1, a synthetic-lethal vulnerability in STAG2-mutant cancers such as bladder cancer, Ewing sarcoma and myeloid malignancies. The post-holder will lead the structural arm of this programme during the screening and hit-development phase: producing STAG1 and STAG1‑containing cohesin complexes, determining cryo-EM structures of these assemblies alone and bound to screening hits, and using this structural information to define binding sites, validate hits and guide compound optimisation together with our medicinal chemistry and drug discovery partners.

The ideal candidate will have a background in structural biology, with hands‑on expertise in single‑particle cryo‑EM and prior experience working on SMC protein complexes.

Main duties / key responsibilities:

Express and purify recombinant STAG1, cohesin and related SMC complexes (e.g. insect cell and E. coli systems) for structural and biophysical studies
Prepare, screen and optimise cryo-EM grids, and collect cryo-EM data using local and national facilities
Carry out single‑particle image processing, 3D reconstruction, model building and refinement, including fitting and validation of bound small molecules
Determine structures of STAG1/cohesin complexes with screening hits to define binding modes and support structure‑guided hit development
Contribute to hit validation using complementary biochemical and biophysical assays of compound binding
Work closely with medicinal chemists, the Drug Discovery Hub team and external partners, communicating structural results to inform compound design
To plan and carry out research in accordance with the project aims
Take initiatives in the planning of research
Conduct and plan own scientific work with appropriate supervisor
Maintain highly organised and accurate records of work, including structural data management and deposition
To attend project and related research group meetings
To interact and collaborate with group members
Contribute to write‑up and publication of work in peer‑reviewed journals
To take an active part in the academic activities of the LMS
To attend and contribute to journal clubs and seminar presentations
Presentation of data at national and international meetings
To form good working relationships with other members of the group as well as internal and external collaborators
To assist others and co‑supervise students when required

Education / Qualifications / Training required (will be assessed from application form):

Essential:

A PhD in structural biology, biochemistry or a closely related field with a focus on cryo‑EM (or a Masters with equivalent research experience)
