Imelda is a Reader in Comparative Medicine. Her research focuses on diseases affecting humans and animals to identify common treatments. Current research falls in two areas: developmental disorders and cancer. Current projects involve using zebrafish models to investigate the role of the microbiome in neuronal development, the role of the myoepithelia and tyrosine kinase receptors in canine mammary tumourigenesis andTasmanian Devil Facial Tumour disease.

We currently have a number of projects that are using a combination of naturally occurring disease models, alongside more traditional models and in vitro techniques to investigate the molecular mechanisms of disease. These include:

1) The role of the microbiome in neuronal development. The microbiome is known to impact upon the function of neurons both in the gut and the central nervous system. However we know little of how the microbiome impacts upon neuronal development. We use germ free zebrafish embryo and larval models to investigate how the absence of the whole or components of the microbiome impact upon neuronal development and neuronal network architecture and the impact of this on embryo/larval behaviour.

2) Canine mammary tumourigenesis. Canine mammary cancer has both similarities and differences to the human disease. We are investigating a key diiference between the two - myoepithelial cell proliferation plays a protective role in canine mammary cancer but does not fulfill this function in humans. We are investigating the mechanisms that control myoepithelial cell proliferation and function in the canine in order to identify how this might be provoked in humans. A key similarity between the canine and human disease is that expression of  the cKIT tyrosine kinase receptor correlates with poor outcomes. We are investigating the function of this receptor in canine mammary cells in vitro.

3) Tasmanian Devil Facial Tumour Disease Tasmanian Devil Facial Tumour Disease is a schwann cell derived cancer that is decimating the Tasmanian Devil population. We are collaborating with colleagues at the University of Tasmania (UTAS) and Southampton University UK to identify signalling pathways that are driving metastasis in this disease. We are interested in how genes that are known to be involved in cell migration in the embryo might also be involved in driving cell migration in this disease.

We are offering BSc and MSc projects in all of these areas so contact us for further information. Prospective MRes and PhD students are also encouraged to contact us for further information

  • Cellular mechanisms of impaired neurodevelopment following early life exposure to air pollution

    UNICEF estimates that over 100 million infants worldwide are exposed to toxic air pollution. We are investigating how this alters vulnerable brain cell development during pregnancy and after birth. Air pollution is a serious common public health concern increasingly associated with morbidity and mortality and resulting in an estimated 7 million premature deaths per year. Air pollution is a mixture of several components, including particulate matter (PM) derived from traffic, fuel burning and industry. The World Health Organisation identified that over 90% of the population are exposed to levels of PM2.5 that are significantly higher than recommended levels.
