Summary
My research is focused on structural studies of medically important biological systems, where specific protein complex formation contributes to human illnesses. I use X-ray crystallography to visualize the whole complex at atomic resolution as well as to determine whether binding partners have undergone changes in shape upon complex formation. This structural information then helps me in drug design with goals to either disrupt or modulate the complex.

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.

Summary
Antibodies are a relatively new class of drugs that directly target molecular mechanisms of disease. Antibody therapies, such as the breast cancer drug Herceptin, have significantly increased our arsenal of effective therapeutics. In collaboration with G2 Therapies, we will use cutting-edge genetic engineering technology to produce fully human antibodies for the treatment of inflammatory diseases, such as rheumatoid arthritis.
Understanding Gene Regulation In Disease Using High Throughput Sequencing

Summary
While genetics refers to the gene sequence, or DNA code, epigenetics refers to all the other factors that control how and when each gene is expressed. New technologies with the ability to sequencing billions of bases of DNA are now being used to study epigenetics. However the data sets are vast and complex. I use statistical and computational approaches in the emerging field of bioinformatics to make sense of this data and relate genome wide disruption of epigenetic marks to diseases.
Improving Bioinformatic Methods For Studying Gene Regulation In Health And Disease

Summary
New methods for analysing genome-wide data will be developed to ease the data analysis bottleneck that currently exists in medical research. Modelling variation in gene expression from single cells, in screens designed to uncover gene function and assays that measure the factors that turn genes on or off will be the focus. Free software will be developed and made available to researchers worldwide to help them interpret the large and complex data sets that are now routine in genomic medicine.
Control Of Genome Regulation And Its Role In Human Disease

Summary
Changes in DNA can lead to differences in susceptibility to developing many diseases. The most common mechanism by which this occurs is through changing when and in which tissues disease-relevant genes get translated into proteins. My research focuses on understanding how DNA changes result in altered gene expression and how this can affect disease susceptibility. This work requires the use of high performance computing and statistical analysis of large genome-scale datasets.

Summary
G protein-coupled receptors are specialised proteins on the surface of cells. They are the targets of 30% of currently available pharmaceuticals. This proposal will examine exciting and novel properties of these proteins that only occur following their assembly into specialised networks in cells. The use of cutting-edge technology will allow us to understand the role of these networks in many diseases. The new information will expand our current knowledge, and facilitate targeted drug design.
Alteration Of Glucose Metabolism By GPCR Activation

Funding Amount

Summary
In type 2 diabetes the effect of insulin to stimulate glucose transport in fat cells and skeletal muscle is impaired so there is great interest in identifying insulin-independent mechanisms that increase glucose transport. Several G protein-coupled receptors (GPCRs) regulate glucose transport independently of insulin but the mechanisms involved in these effects are largely unknown. This project investigates how GPCRs regulate glucose homeostasis and will evaluate them as potential treatments.
