The role of nuclear motor proteins in chromatin dynamics
Our laboratory has been working on active and rapid gene and chromosome movement with interphase nuclei using gene or chromosome positioning assays via bio-imaging, data analysis and live imaging. We have identified a nuclear motor mechanism that is involved in this active and directional movement containing motor proteins, such as actin and myosins, that form functional complexes. These proteins and complexes are responsible for taking genes and chromosomes to new non-random locations and structures involved in gene expression or silencing. This project would investigate the mechanism of gene/chromosome movement within cells by interfering with the ability of these proteins to build these complexes using specific drugs and genomic engineering. The project will then combine cell culture, fluorescence in situ hybridisation, 3D and 4D imaging and analysis, assessing the epigenetic status of chromatin being relocated with ChIP-seq and CRISPR/cas9 genomic engineering.

This is a self funded topic
Brunel offers a number of funding options to research students that help cover the cost of their tuition fees, contribute to living expenses or both. See more information here: https://www.brunel.ac.uk/research/Research-degrees/Research-degree-funding. The UK Government is also offering Doctoral Student Loans for eligible students, and there is some funding available through the Research Councils. Many of our international students benefit from funding provided by their governments or employers. Brunel alumni enjoy tuition fee discounts of 15%.
Dr Joanna Bridger
- I have been at Brunel University London since the start of this century. This is when I established my own independent laboratory - The Laboratory of Nuclear and Genomic Health. Our research concerns how the genome is spatially organised, influenced and manipulated within its environment, the cell nucleus. The group has had a number of major advances and is currently focused on aspects of genome behaviour in replicative senescence, the premature ageing disease Hutchinson-Gilford Progeria Syndrome, host:pathogen interactions and female cancers. We are wish to understand how structures such as the nuclear lamina, nucleoskeleton and nuclear motors influence the functionality of the genome.
I also teach Cell Biology at levels 2 and 3, Developmental Biology at level 2, Gene Expression and Epigenetics and Cellular and Organismal Ageing at Masters level. The lab is always full of PhD, Masters and undergraduate students doing their various projects.
I am also the Head of the Genome Engineering and Maintenance network established from the depth and interest in Genome Biology that has developed over time in Biosciences at Brunel. My other role is External Engagement where I organise all the external interactions we have in our division
