Summary
B cells are responsible for producing antibody that protects us from infection. Disruption of healthy B cell function can lead to a myriad of diseases including immunodeficiency, autoimmunity and blood cancers such as leukaemia. The aim of my work is to use powerful microscopy to visualise how mutated B cells interact with their surrounding environment in real-time. These studies will allow the development of new treatments for cancer and immune conditions that target these interactions.

Summary
B cells are essential for the protection against infections. This application aims to identify new genes that are crucial for the development or function of B cells and will investigate how mutations in newly discovered genes contribute to defects in the development and function of B cells and the pathogenesis of B cell leukaemia.
Chronic infectious diseases have a devastating effect on global health. HIV and Plasmodium falciparum both cause chronic disease and have evaded effective vaccine design. Vaccines rely on immune memory – the ability to clear an infection rapidly to a previously encountered pathogen. This proposal investigates the formation and dysfunction of immune memory in chronic infectious diseases, which will be vital for creating new and effective vaccines.
Nerve cell survival is dependent on both growth-promoting factors and factors released by neurotransmission, which can promote recovery in neurodegenerative conditions by overriding cell death pathways. The molecule responsible for activating death pathways in the nervous system is called p75. This project will investigate how p75 results in cell death, how synaptic signals can prevent the activation of the p75 death pathway and whether blocking p75 function can limit neurodegeneration.
Nuclear architecture is critical to the preservation of genome integrity. The aim of this research proposal is to delineate the role of chromatin organisation in transcription factor target search and damage site recruitment of DNA repair factor machinery. To achieve this I have developed fluorescence microscopy methods to monitor changes in chromatin structure with submicron resolution. Only with this technology can I determine how chromatin dynamics maintain genome integrity or induce disease.

Summary
We plan to develop the instruments and associated technologies required to directly visualise biological processes as the occur in real-time deep inside living organisms. Thus we will use two-photon microscopy to provide deep tissue imaging of immune cell interactions in mouse models and confocal endomicroscopy to provide molecular imaging of cancer biomarkers in patients with colorectal cancer.
