Overview

We are looking for a talented and motivated student to join our interdisciplinary team in Professor Greg Hannon’s lab at the CRUK Cambridge Institute (CRUK CI), to investigate the molecular mechanisms of small RNA-mediated chromatin silencing. As a whole, the Hannon laboratory has broad interests that range from discovery research to cancer biology, as well as a strong commitment of developing and using new tools to address cutting-edge questions in these fields.

This studentship is embedded within the piRNA team, consisting of both wet- and dry-lab scientists that are studying RNA, chromatin and transposon biology, covering all aspects of this RNA-based immune system, including the biogenesis of small non-coding RNAs and the dynamics of chromatin modifications required for transposon silencing.

Project details

This project aims to advance our understanding of small RNA-mediated chromatin silencing using advanced genomics and chromatin profiling methods along with CRISPR/Cas9-mediated cell line engineering and various animal models. You will study the effects of the activation or depletion of chromatin-modifying enzymes using transcriptomics and histone mark profiling as well as by live imaging approaches. As part of this project, you will have the opportunity to gain computational data analysis skills. This studentship comes with the opportunity to explore novel techniques that allow spatial profiling of chromatin marks and RNA output and apply these methods to questions with biological relevance in RNA-guided chromatin silencing.

Preferred skills/knowledge

You will have excellent laboratory skills, a strong background in molecular biology and/or biochemistry, and a keen interest in chromatin research. Ideally more than 6 months of practical research experience is preferred; while familiarity with tissue culture, genome editing, or live-imaging approaches would be desirable.

Funding

This four-year studentship is funded by CRUK CI and includes full funding for University fees and an index-linked stipend starting at £22,500 for four years.

Eligibility:

We welcome applications from both UK and overseas students. Applications are invited from recent graduates or final-year undergraduates who hold or expect to gain a First/Upper Second Class degree (or equivalent) in a relevant subject. Applicants with relevant research experience are strongly encouraged to apply.
