Summary
Breast cancer is a highly heterogeneous disease with multiple molecular and histological subtypes. We propose to use novel genetically engineered mice to understand breast inter-tumoral heterogeneity by dissecting the cells of origin of breast cancer in vivo. Initially, we will examine whether long-lived stem or progenitor cells are the targets of breast carcinogenesis induced by a progesterone derivative using our state-of-the-art multi-coloured reporter models to track the cells in vivo.
Single Cell Genetic Profiling To Reveal Molecular And Cellular Changes In BRCA Preneoplastic Tissue

Summary
The initial molecular and cellular events that lead to breast cancer in women with BRCA1 or BRCA2 mutations are unknown. We will use state-of-the-art genomic tools (Single Cell RNA-seq and whole genome sequencing) to determine how cancer begins in absence of normal BRCA genes. Single cell genomic profiling of stem and daughter cells from pre-cancerous breast tissue will be used to identify early-indicator molecular changes that could be exploited in the clinic.
I am a clinician-scientist engaged in basic, translational and clinical breast cancer research, with the long-term goal to identify and exploit novel cancer targets to improve patient outcomes. My research, which covers both sporadic and hereditary forms of breast cancer, is focussed on elucidating the breast epithelial cell hierarchy, in order to identify key regulators responsible for breast epithelial cell proliferation, differentiation and cancer.

Summary
Whilst the outcomes for women with breast cancer have improved significantly, the incidence of breast cancer continues to increase. Research needs to focus on prevention now to try to stop the increase. Apart from age, our reproductive behaviour is the largest risk factor for breast cancer. If a woman does not bear children, or has them after 35 years of age, she is at 25-50% increased risk of breast cancer. We would like to determine whether the breast stem cells play a role in this and why.
Isolation And Characterisation Of Novel Progenitor Cells In The Mammary Epithelium And Their Role During Carcinogenesis.

Summary
Stem and progenitor cells in the breast are the immature cells from which mature cells are derived. Their are long-lived, resistant to death and can produce multiple types of mature cells, implicating them as cells from which breast cancer may originate. We aim to search for novel cell surface markers that define the progenitor cells in the mouse mammary gland. The data gathered from this project may facilitate the development of targeted therapies to the cells of origin in breast cancer.
I am a cellular biologist studying lineage commitment and differentiation in the mammary gland. Key interests include defining transcriptional regulators that are important for mammary gland development and oncogenesis, and the characterisation of stem cells and other epithelial cell types in breast tissue.
Development Of Targeted Therapies To Reverse The Effects Of Ageing And Disease On Wound Healing And Tissue Generation

Summary
Despite success with the production of new tissues and organs in laboratory animals, tissue engineering in humans remains elusive. Emerging evidence suggests that ageing and diseases such as diabetes can adversely affect human stem cell regenerative capacity. Characterizing the effects of ageing and disease on stem cells during tissue generation is the first step in reversing these effects, paving the way for the production of new tissues and organs for use in human clinical trials.
