About the Project

A PhD studentship is available to work in the laboratory of Dr. Fiona Wardle ( in the Randall Centre for Cell and Molecular Biophysics, King’s College London. The successful applicant will be joining a dynamic, interdisciplinary lab, within one of the world’s top research universities

Our laboratory focusses on the networks of gene regulation that control tissue and organ formation in the early vertebrate embryo, and disease progression, particularly cancer, in the adult. We use a combination of approaches to study gene regulation including cell biology, molecular biology, experimental embryology, genomics, and computational biology in a variety of systems including zebrafish, mammalian stem cells and cancer cells.

We are seeking a highly motivated and enthusiastic candidate with a background in developmental biology, biochemistry or computational biology to study gene regulatory networks in the early zebrafish embryo.


This project will investigate the function of enhancer regions in regulating gene expression in zebrafish mesoderm formation. Using publicly available genomics data and 4C-seq data generated in house, the candidate will identify putative enhancer regions that regulate expression of mesodermal genes in the early embryo. The function of these will be tested using reporter assays and genome editing (CRISPR) to mutate the enhancers. The selected candidate will gain experience in zebrafish embryology, genomics, molecular biology, microscopy and bioinformatics.

Should candidates be interested in other projects in the laboratory (see:, please feel free to contact Dr Fiona Wardle for an informal discussion.


The candidate will be joining an interdisciplinary team that is based in the Randall Centre at the Guy’s Campus of King’s College London. Our group is part of a vibrant department with numerous researchers using genomics, microscopy, biophysics and computational biology to investigate development and cell biology, and the candidate will gain exposure to numerous techniques and model systems.

The Health Sciences Doctoral Training Centre will also provide methods training and opportunities for career development activities, such as presentation and writing skills (see:


Prospective candidates should have a 1st or 2:1 level qualification in developmental biology/biochemistry/computational biology or a related programme. Applicants are also required to meet King’s English language requirements (Band D,

To apply, please send a CV, transcript and statement of interest to Dr. Fiona Wardle ().

Funding Notes

There is currently no funding attached to this PhD call and the successful applicant will be expected to provide their own funding. We require candidates that have secured, or wish to secure, their own competitive funding from overseas government agencies or employers.
