Summary
There is a desperate need for biomarkers and therapeutics for Motor Neurone Disease (MND). Mutations in a growing list of genes are implicated as a cause of MND, although the way these cause MND remains a mystery. I aim to build a uniquely positioned research team that approaches this problem from a protein centric view and incorporating strategic collaborative efforts to the understanding of the pathogenesis of MND; the longterm goal of which is translation to biomarkers and therapeutics.
My research is aimed at understanding how the structure and dynamics of proteins dictates their function. I use X-ray crystallography to determine the shapes of proteins. Proteins are not static, however - they move in complicated ways, and often their motion is critical to their function (molecular motors, for example). It is very difficult to 'watch' this movement in the lab, so I use computer simulation to try to understand how proteins move.
The Role Of Clusterin In Preventing Atherosclerosis

Summary
In atherosclerosis, plaques are formed when damaged low density lipoprotein (LDL) and fibrinogen are deposited inside blood vessels. Clusterin is a protein that stabilises damaged clients in soluble complexes, thus preventing their deposition. This project will investigate the ability of clusterin to prevent the deposition of damaged LDL and fibrinogen. Elucidation of mechanisms for preventing protein deposition will identify novel therapeutic targets for the treatment of atherosclerosis.
ER Stress-Unfolded Protein Response A Critical Metabolic Pathway For Airway Remodelling In Asthma

Summary
Airway remodelling in asthma is associated with poor clinical outcomes and is not prevented by current treatments. We have found endoplasmic reticulum stress (ERS) and associated unfolded protein response (UPR), a crucial process involve in cellular protein folding, play a key role in airway remodelling in asthma. This study will investigate whether inhibition of ERS prevents goblet cell metaplasia, mucus hypersecretion and fibrosis and can be used as a therapeutic strategy for severe asthma.
