Cancers arise as a result of the impairment of critical cellular processes following the mutation of important regulatory genes. I am a molecular biologist and I study how the proteins of the Bcl-2 family regulate apoptosis, a process of cell death essential to maintain homeostasis in multicellular organisms, with the aim of designing drugs to kill cancer cells selectively. I am also interested in discovering new genes involved in the development of cancer using new genomics technology.
Too little or too much of the essential element iron is the cause of some of the most common disorders affecting humans. These include iron overload, anaemia, and anaemia of chronic disease. This project examines the genes and the roles they play in regulating iron levels in the body, and the consequences to the individuals when they are mutated. Ultimately I intend to develop therapeutics and diagnostics which will help early diagnosis and effective treatment of these disorders.
This is an application for reappointment as a Principal Research Fellow. My primary area of research is preclinical studies of addiction, with a particular emphasis on relapse. I am increasingly engaged in translational studies.
Improving Outcomes In Heart Failure Through Basic, Clinical And Translational Research
Funder

Funding Amount
$951,005.00
Summary
Heart failure (HF) is a common, chronic cardiovascular condition characterised by a reduced capacity of the heart to function. Patients with HF have a poor quality of life and significantly reduced survival. My proposed programme of research will improve the understanding of heart failure (HF) and lead to better treatments.
Malaria is a devastating disease of global significance. With mounting resistance to current drugs and no licensed malaria vaccine, there is a pressing need to search for new strategies to reduce the global burden of malaria. My research program aims to understand how the parasites that cause malaria extensively renovate the cells in which they reside and subvert their host so that they can thrive and survive, with a view to identifying new pathways that can be targeted by drugs or vaccines.
Liver Injury And Iron Homeostasis In Health And Disease

Funding Amount
$631,370.00
Summary
Iron disorders and liver disease are a significant burden on society, affecting many in the prime of their life. Disordered iron metabolism also plays a significant role in many disorders and diseases including cancers, neurodegenerative and iron overload disorders, and anaemia associated with chronic disease. My objective is to understand the molecules and mechanisms involved, and to develop strategies and reagents to diagnose, prevent and treat liver and iron-related disease.
The aim of this application is to find new therapeutic strategies for genetic epilepsy. "Disease in a dish" models as well as whole animal models will be generated that contain patient gene mutations and the underlying disease processes will be characterised. Using these models a range of existing and new drugs will be tested to select those that most completely reverse these disease processes. These results will feed into clinical trials in patients with appropriate genetic profiles.
Microenvironmental Impact In The Treatment Of Acute Lymphoblastic Leukemia

Summary
Acute lymphoblastic leukemia remains one of the leading causes of death in children and outcomes for adults with this disease remain poor. This project examines how manipulation of the environment where leukemia arises can be used to therpaeutic advancage. Acute lymphoblastic leukemia cells are highly dependent on the support provided by bone marrow cells but the mechanisms are not well understood. Disrupting signals from the bone marrow cells has potential as a therapeutic strategy.
An inability to control human fertility is an issue of global significance. Frequently both unwanted pregnancies and infertility result from the same origin, a lack of understanding of how germ cells are produced. Within this fellowship I will define key processes involved in the manifestation of male fertility. Further I will extend these insights into both the fertility clinic but also into human health more broadly.
Variation in our genetic makeup can cause serious brain disorders such as epilepsy. The goal of this research is to determine how variation in an epilepsy patients genes produce fundamental changes in brain function that lead to epilepsy. This is a multidisciplinary program that combines clinical, genetic, electrophysiological, morphological and computational approaches to create a fundamental understanding of the genesis of this important disease.
