Transcription factors (TFs) read cis-regulatory information encoded in the genome. However, they must compete with structural chromatin proteins such as nucleosomes for access to DNA motifs. It is unclear what features discriminate used from unused binding sites with similar motifs, in vivo. To provide insight and general principles of TF biology, I will express variants of a model TF in mammalian cells and test the contribution that specific molecular properties have on genomic binding.
The Role Of The Chaperone NASP In Regulating Histone Dynamics During DNA Replication And Repair

Summary
To fit inside our cells, DNA is intricately packaged with histone proteins into chromatin. All aspects of cell function are regulated by this packaging. My research will help us to understand how the cellular life of histones is controlled by a protein called NASP to ensure the packaging is correctly maintained and reorganised during normal genome function.
The Role Of Ikaros In Establishing Regulatory Networks For Lymphocyte Development

Summary
Ikaros is a protein that regulates gene expression during development of lymphocytes from blood stem cells. Ikaros has a profound importance in normal and malignant lymphocyte development, but we still do not know how it controls these processes. The aim of my study is to identify genes regulated by Ikaros and the molecular mechanisms of their regulation. This study will contribute to understanding of the regulatory network controlling the development and function of lymphocytes.
