The Institute of Cancer Research, London, is one of the world’s most influential cancer research institutes, with an outstanding record of achievement dating back more than 100 years. We provided the first convincing evidence that DNA damage is the basic cause of cancer, laying the foundation for the now universally accepted idea that cancer is a genetic disease. Today, The Institute of Cancer Research (ICR) leads the world at isolating cancer-related genes and discovering new targeted drugs for personalised cancer treatment.

Under the leadership of our Chief Executive, Professor Paul Workman FRS, the ICR is ranked as the UK’s leading academic research centre. Together with our partner The Royal Marsden, we are rated in the top five cancer centres globally.

The ICR is committed to attracting, developing and retaining the best minds in the world to join us in our mission – to make the discoveries that defeat cancer.

We seek to appoint a Postdoctoral Trainng Fellow to the research team led by Dr Sebastian Guettler in the Divisions of Structural and Cancer Biology. Work in the Guettler laboratory centres on the elucidation of signal transduction mechanisms relevant to the function of cancer cells, in particular the Wnt/b-catenin network and telomere homeostasis and their control by poly (ADP-ribosyl)ation. We take a multi-disciplinary approach that combines structural biology, both by X-ray crystallography and cryo-electron microscopy, biochemistry, biophysics and functional studies in mammalian cells.

The Cancer Research UK-funded Postdoctoral Training Fellow will analyse the function of poly(ADP-ribose)polymerase (PARP) enzymes by using a combination of cryo-electron microscopy, biophysical and biochemical approaches. The emphasis will be on the structural characterisation of proteins/protein complexes by cryo-EM and the exploration of hypotheses raised by structural findings using purified proteins in biochemical assays. The position will coincide with a major expansion of cryo-EM capabilities at the ICR in 2019/20, which will provide a state-of-the-art infrastructure and outstanding research and training opportunities.

Appointment will be on a Fixed Term Contract for 3 years. 

Research in the Divisions of Structural Biology and Cancer Biology focuses on the functional, biochemical, and structural characterisation of cellular processes relevant to cancer and cancer therapy.

The Division of Structural Biology has managed facilities for protein production, with expertise in multi-subunit expression (insect cell, yeast and bacterial expression, including a 60-litre fermentor), protein crystallography (crystallisation robots, Bruker Microstar and CCD detector) and cryo-electron microscopy (FEI Tecnai T12 and F20). The installation of a state-of-the-art FEI Glacios/Falcon 3 cryo-electron microscope is currently in progress. Regular access to shared cryo-EM facilities, such as eBIC, is available. Moreover, the Institute of Cancer Research is part of the London Consortium for Cryo-EM, hosting an FEI Titan Krios cryo-electron microscope equipped with a Volta phase plate, a Gatan Bioquantum energy filter and K3 detector (available in 2019). The Division is also well-equipped with instrumentation for biophysical analysis (e.g. ITC, fluorescence, multi-angle light scattering).

The Division of Cancer Biology provides a state-of-the-art infrastructure for mammalian cell culture, light microscopy, mammalian genetics, chemical biology and proteomics.
