Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to p ....Programming of appetite and bodyweight by the interaction of maternal diet and angiotensin during peri-natal life. The project describes a phenotype for appetite and body weight that can be altered by maternal dietary omega-3 PUFA (environmental factors), at a critical period during peri-natal life (developmental phase) and that the effect on body weight is opposite when endogenous angiotensin is increased (hormonal factor). The project aims to discover how these different factors interact to produce the phenotype by defining the critical period and systematically identifying genes that are expressed during this period. The effect of manipulating maternal dietary omega-3 PUFA and the role of angiotensin will then be examined. The project will discover how genetic, hormonal and environmental factors interact during the perinatal period of life to program food intake and body weight in adult life. Read moreRead less
Molecular characterization of the role of menin in embryonic development. Menin is a protein that is necessary to prevent development of tumours. Deletion of menin in mice causes embryonic death. We think this is because menin is necessary in the placenta. This project will examine the role of menin in the fetus and the placenta, and provide information about how normal pregnancy and fetal growth is controlled.
Genetic control of tissue growth in animals. This project aims to understand how the animal body grows. This project expects to generate new knowledge and understanding of the genetic programs that govern the size and shape of animal tissues, through use of cutting-edge genome editing approaches in laboratory animals. Expected outcomes of this project include the production of genetically engineered animals with altered tissue growth, development of new theories for how tissue growth is normal ....Genetic control of tissue growth in animals. This project aims to understand how the animal body grows. This project expects to generate new knowledge and understanding of the genetic programs that govern the size and shape of animal tissues, through use of cutting-edge genome editing approaches in laboratory animals. Expected outcomes of this project include the production of genetically engineered animals with altered tissue growth, development of new theories for how tissue growth is normally controlled and how it can be manipulated industrially. This should provide significant benefits, impacting stem cell biology (improving stem cell production), tissue engineering (improving growth of artificial tissues), veterinary science and agriculture (improving productivity).Read moreRead less
Drugging the undruggable: Development of novel technologies to selectively regulate the expression of targets driving cancer and other diseases. Transcription factors are “undruggable” targets playing a principal role driving cancer. This project will create novel therapeutic strategies to inhibit transcription factors and other elusive targets differentially expressed in diseased cells, without affecting normal tissue. It proposes to construct engineered proteins able to bind and modify specifi ....Drugging the undruggable: Development of novel technologies to selectively regulate the expression of targets driving cancer and other diseases. Transcription factors are “undruggable” targets playing a principal role driving cancer. This project will create novel therapeutic strategies to inhibit transcription factors and other elusive targets differentially expressed in diseased cells, without affecting normal tissue. It proposes to construct engineered proteins able to bind and modify specific key genes deregulated in cancer, to correct their expression and stably reprogram the phenotype of the tumour cell in a normal-like state. It outlines the engineering of novel synthetic agents to block specific protein-protein interactions in cancer cells and to induce potent tumour cell death. This work will generate novel and selective therapeutics to treat un-curable forms of tumours.Read moreRead less
Chromatin barriers in Plasmodium falciparum gene regulation. Malaria is a major world disease that kills around 2 million people annually. The genome of the causative agent has now been completely sequenced, but we still know very little of how and why some genes are activated while their neighbours are turned off. I will study the DNA barriers that separate such genes, and the proteins that interact with these regions to better understand how genetic regulation functions in these parasites. A b ....Chromatin barriers in Plasmodium falciparum gene regulation. Malaria is a major world disease that kills around 2 million people annually. The genome of the causative agent has now been completely sequenced, but we still know very little of how and why some genes are activated while their neighbours are turned off. I will study the DNA barriers that separate such genes, and the proteins that interact with these regions to better understand how genetic regulation functions in these parasites. A better understanding of gene regulation in malaria parasites will help us to better combat the tricks utilised by this and other organisms to elude our immune systems.Read moreRead less
The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.
Functional analysis of nucleic acid binding protein that is essential for mammalian development. The complex pathway by which the information contained in our genes is used by the body is far from understood. The project will explore an important protein component of this pathway, that is essential for normal embryonic development. The aim of this project is to understand how this protein regulates human development.
I am a molecular geneticist with a primary focus on the identification of genes and sequence variants underlying susceptibility to, and progression of, various tumour types _ in particular tumours of the skin (moles and melanoma), oesophagus, ovary, lung
Genetic control of plant organ growth. Plants organs, such as leaves and petals, have a distinct size and shape reflecting differences in growth. Despite its importance, very little is known about the mechanisms that regulate growth. The objectives of this proposal are a) to test whether organ growth depends on cell-cell signalling and b) to identifying genes that regulate growth, and to characterize their molecular function.
Marsupial germ cells and genes. Germ cells are the most fascinating cells in the body, since theirs is the unique responsibility for transmitting life from generation to generation. Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the ....Marsupial germ cells and genes.

Studies in mice have suggested that position in the embryo determines their origin, but the early embryology of the mouse is so different from that of other mammals that the events need confirming and extending in another species. The simplified embryology of the tammar wallaby makes it ideal for studying one of the most fundamental questions in the whole of biology: what is the basis for the primal distinction between sex and soma?Read moreRead less
