About the Project
Research in our lab focuses on understanding the transcriptional and epigenetic reprogramming events that take place in normal mammalian development, and on uncovering novel axes of gene regulation. Particularly, we are interested in the function of transposons which have been greatly understudied in development, despite making up 50% of our genomes. Our recent research(1-2) indicates that certain transposons are expressed and play essential roles during early mouse development, and we are particularly interested in dissecting how transposon regulation is important during embryogenesis.
We employ a combination of candidate and genome-wide approaches in ESCs, CRISPRi/a technology, bioinformatics, high-resolution imaging and molecular embryology to understand 1) mechanisms of transposon regulation and 2) the implications of transposon expression for ZGA, cell fate, embryogenesis and disease.
Projects in the lab are focused on several exciting aspects of transposon regulation:
i) Role and regulation of ERVL transposons in the totipotency-to-pluripotency transition in early embryos and ESCs(1-4)
ii) Dissecting novel instances of transposon function in cell fate transitions
iii) Exploring transposon mis-regulation in disease
The Chromatin and Development Group is a recently-established Lab within the Epigenetics division of the MRC London Institute of Medical Sciences (MRC LMS) – a world-class research institute closely associated with Imperial College. The successful student will be funded by a prestigious LMS 3.5 year PhD studentship.
If successful the student would receive full tuition fee payments for 3.5 years as well as a tax free stipend amounting to £21,000pa paid in monthly installments for the duration of their studentship.
