Postdocs
As a postdoc at the ICR, you’ll be working at the forefront of cancer research, in an environment that’s collaborative, international and inclusive.
We aim to attract the best scientific minds, wherever in the world they come from. With postdocs from all over the UK and the world, you'll be joining a welcoming community that prioritises training the next generation of world-leading researchers. You’ll also benefit from our strong links with our partner hospital, The Royal Marsden NHS Foundation Trust, as well as our links with companies through industrial partnerships.
Benefits and culture
We offer a competitive salary, rigorous training, many opportunities for professional development, and an open and inclusive working culture. Our PostDoc Association, faculty and learning and development team work closely to support postdocs.
We also offer generous annual leave and family-friendly policies that support parents, including stop the clock, which supports maternity leave during research.
Reimbursing your visa and other costs
Successful applicants will be able to claim the cost of their visa and of the immigration health surcharge (IHS) for themselves and for their dependants once they have joined. This is a taxable benefit. Applicants often find the UK visa application process to be less onerous than for some other countries, such as the United States.
We provide extensive training and development opportunities that will help prepare for your future career inside or outside academia.
Throughout your postdoc fellowship, you’ll be offered training and support to help you to develop your skills in key areas such as high-impact publishing, managing research projects, leadership and career planning.
Getting started
We run training sessions for new postdocs, as well as a postdoc buddy system to help you to settle into your new role. We normally pair you with someone from a different discipline, to broaden your network. We can also try to match you with someone who speaks your native language.
Training and support
As signatories of the Concordat to Support the Career Development of Researchers, we are committed to providing our postdocs with at least 10 days each year for their personal and career development. We offer a wide range of activities that you can tailor to your career stage, research interests and career ambitions. These include:
- On-the-job training – such as shadowing funding panels, grant writing, peer review, supervising and mentoring others, lab visits, committee membership and project-related placements.
- Informal opportunities – such as building professional networks, engaging with the ICR Postdoc Committee, participating in conference organising committees, mentoring (as mentor or mentee), and 1:1 career support with consultants employed by the ICR.
- Formal training and professional development courses – on topics ranging from supervisor training, writing and publishing, and statistics, to project management and entrepreneurship.
The Pathway to Independence – a competitive programme that we run in collaboration with the Wellcome Sanger Institute and CRUK, is also an option for postdocs who are aiming to become academic team leaders.
We also provide training on science communication and outreach to support your participation in our public engagement programme.
You'll be joining a diverse and talented community of postdocs who come to work here from all over the UK and the world.
We’ve around 150 postdocs working at the ICR from across dozens of countries around the world at any one time. Several groups can help you to settle in, build a social network and get involved with life at the ICR.
PostDoc Association
Our Postdoc Association (PDA) brings together postdocs across the ICR for professional and social events, which include away days and conferences. It provides a community for postdocs to feel connected and supported.
Join our networks
From our LGBT+ Network and our forum on race and ethnicity to sports clubs and seminars, you’ll have the chance to connect with like-minded researchers and build your network.
Our active Postdoc and Alumni LinkedIn group is also a great way to connect with others and get answers to common questions – from what it’s like to rent in London to how to set up a UK bank account.
Former ICR postdocs are also welcome to subscribe to Network, our alumni e-newsletter, so they can continue to feel part of our community even after moving on in their careers.
There are lots of reasons why early career researchers come to do a postdoc at the ICR. We spoke to some of our past and present postdocs to find out why they chose the ICR.

PDTF - Homologous Recombination Defective Cancers ( Profs Chris Lord and Andrew Tutt)
Under the guidance of Professors Chris Lord and Andrew Tutt, we are seeking to appoint a creative and motivated Postdoctoral Training Fellow to study how drug resistance emerges in homologous recombination defective (HRD) breast cancers and how this could be targeted. The post would suit a candidate with strong functional genomics and DDR biology experience who has a strong desire to work on solving clinical problems. We strongly encourage researchers with published first author manuscripts from their PhD training period to apply. About you The successful candidate must have a PhD in biology, genetics or other associated subjects and a knowledge of cancer biology, experimental genetics and of DNA damage response biology. An understanding of the clinical management of cancers is desirable, as is experience with in vivo models of cancer. Candidates who are nearing completion of their PhD are encourage to apply, but confirmation of awarded PhD is required within 6 months of employment. The ICR has a workforce agreement stating that Postdoctoral Training Fellows can only be employed for up to 7 years as PDTF at the ICR, providing total postdoctoral experience (including previous employment at this level elsewhere) does not exceed 7 years. For general information on Postdocs at The ICR, more information can be found here. Department/Directorate Information The Precision Oncology Laboratory, led by Profs. Chris Lord and Andrew Tutt, focuses upon identifying and understanding tumour specific dependencies, such as synthetic lethal effects, as a means to design novel approaches to treating cancer (Heider et al. Nat Genet. 2025). We have made major advances in identifying synthetic lethal interactions involving, for example, PARP inhibitors (Farmer et al Nature 2005, Edwards et al Nature 2008, Pettitt et al Cancer Discovery 2020, Krastev et al Nature Cell Biol 2022), ATR inhibitors (Williamson et al, Nature Communications 2016) and Polq inhibitors (Zatreanu et al Nature Comms 2021). We unashamably focus on clinical problems such as therapeutic resistance and the development of new targeted therapeutic approaches in cancer and aim to generate pre-clinical information that informs the design and interpretation of clinical trials and the identification of novel targets for drug discovery programmes. The Breast Cancer Now Toby Robins Research Centre, within the Division of Breast Cancer Research at the ICR, began 25 years ago and was the first centre in the UK entirely devoted to breast cancer research. Our goal is to advance research into the causes, diagnosis and treatment of breast cancer. It is located in state-of-the-art laboratory space, with excellent core facilities and is funded through a long-term renewable programme grant from Breast Cancer Now. The Centre is Directed by Clinician Scientist Professor Andrew Tutt. Professor Chris Lord, a Cancer Biologist is Deputy Director of the Centre. Our Breast Cancer Research Centre was awarded the 2022 AACR Teams Science awarded with our breast cancer clinical partners in the ICR’s CTSU clinical trial unit and Royal Marsden Hospital, and also received recognition in an award to the ICR for the 2024 Queen’s Anniversary Prize for transforming lives through world-leading breast cancer research.
