Contact term: Two full-time, fixed-term (4 years) positions on Crick terms and conditions of employment.
The projects in the group involve structural studies of virus-host interactions and viral replication. Large part of the work in the laboratory is directed towards understanding the process of retroviral DNA integration, the mode of action of HIV integrase inhibitors and the mechanisms the virus uses to develop resistance to these drugs.
Examples of open research questions that align with the group's interests include how HIV integration machinery is affected by epigenetic status of chromatin, and what roles host cell factors play in this process. One of the goals will be to determine the structure of the lentiviral integration machinery, the intasome, in complex with chromatinized target DNA and host factors. Another challenging project will be to unravel the mechanism of intasome disassembly following integration. The particular goals and projects will be decided upon discussions with the successful applicants.
The main techniques used in the laboratory are cryo-electron microscopy and X-ray crystallography, supported by state-of-the-art facilities in the Institute. The Cryo-EM facility provides access to all necessary equipment, including two Titan Krios 300-kV microscopes each equipped with a Volta phase plate and Falcon III detector (one has an additional Gatan energy filter and K2 detector) and these are complemented by a Talos Arctica 200-kV instrument and a 120-kV Spirit TEM screening microscope. Cryo-EM data processing is carried out using in-house CPU/GPU cluster. The Crystallography facility harbours a wide range of high-end instrumentation, including two Rock Imager 1000s for high-throughput crystallization screening and optimization at two temperatures, two Formulator-16s, and an X-ray suite equipped with a Bruker D8 Venture X-ray diffraction system with an Excillum liquid MetalJet X-ray generator coupled to the latest photon counting detector producing a highly intense 75-mm beam that allows testing small crystal systems in-house and a fully automated crystal plate adapter capable of examining crystals in-situ.

The Francis Crick Institute is a new research institute with an international reputation for cutting edge research into basic biology and is committed to training the next generation of research scientists.
The Francis Crick Institute is a biomedical discovery institute dedicated to understanding
the fundamental biology underlying health and disease. Its work is helping to understand
why disease develops and to translate discoveries into new ways to prevent, diagnose and
treat illnesses such as cancer, heart disease, stroke, infections, and neurodegenerative
An independent organisation, its founding partners are the Medical Research Council (MRC),
Cancer Research UK, Wellcome, UCL (University College London), Imperial College London
and King’s College London.
The Crick was formed in 2015, and in 2016 it moved into a brand new state-of-the-art
building in central London which brings together 1500 scientists and support staff working
collaboratively across disciplines, making it the biggest biomedical research facility under a
single roof in Europe.
The Francis Crick Institute will be world-class with a strong national role. Its distinctive
vision for excellence includes commitments to collaboration; to developing emerging talent
and exporting it the rest of the UK; to public engagement; and to helping turn discoveries
into treatments as quickly as possible to improve lives and strengthen the economy.
Postdoctoral Training 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 help guide PhD and MSc students in their research.
The responsibilities include but are not limited to:
- Investigating research questions and developing specific research project(s) under guidance from the group leader.
- Providing specialist advice and guidance, sharing knowledge and expertise for the benefit of others.
