Postdoctoral Fellow

Reporting to: George Kassiotis, Principal Group Leader

Contact term: This is a full-time, fixed term fixed term position for 4 years on Crick terms and conditions of employment.

The Research Group

The Postdoctoral Scientists will carry out research on transcriptional and epigenetic mechanisms underlying the initiation, progression and immune control of human cancer. Particular emphasis will be placed on endogenous retroviruses and other endogenous retroelements that current work in the lab has identified as cancer-specific. The focus is the creation of novel or alteration of existing gene function, through co-option of endogenous retroelements in cancer.

The Project

This role will be pivotal in ensuring continuation of research on endogenous retroviruses in human cancer in the Kassiotis lab. The post holders will be part of a team of researchers in the Kassiotis lab at the Francis Crick Institute.

Specific objectives will include, but not be limited to:

  • Designing, performing, analysing and interpreting experiments to investigate the exaptation of endogenous retroelements in the context of human cancer, which will be studied in humans as well as animal models

  • Working within a team that carries out research on immune reactivity to retroviral antigens in the context of infection and cancer.

  • Carrying out the processing, analysis and integration of distinct next generation sequencing and multiple ‘omics data.

  • Using existing, and developing and maintaining pipelines for the analysis of multiple ‘omics data.

Postdoctoral Fellows will lead their own projects, contribute to other projects on a collaborative basis (both in the lab and with external collaborators) and may guide PhD students in their research. The ability to work in a team is essential.

Key experience and competencies

The post holder should embody and demonstrate our core Crick values:

Bold; Open; Collegial


  • PhD in cancer biology, computational biology or related disciplines (or in the final stages of completion)

  • A strong background in statistical analyses

  • A strong background in state-of-the-art cell biology techniques

  • Experience in the analysis of next generation sequencing data

  • Excellent theoretical knowledge of the principles of genetics, cancer biology and cancer immunology

  • Experience with scripting language (Python or Perl), R statistical programming language, Bioconductor, and with LINUX based systems

  • Ability to design and maintain analysis pipelines

  • The post holder is expected to be creative and motivated, conscientious and able to work independently, but also to interact well within the team

  • Excellent record keeping and ability to communicate well are also essential
