I am a molecular-cell biologist studying the genetic regulation of intestinal homeostasis in development and disease with the aim of identifying novel molecular targets for the treatment of disease and that can be validated in relevant preclinical mouse models.
This work will analyse how cells, the building blocks of tissues, are organized together to form functioning organs. It focuses on the adhesion molecules that allow cells to recognize one another, which cooperate with the internal skeleton of cells to link them together. We aim to understand how these cellular systems work normally and how they are targeted to disrupt tissue integrity in diseases like cancer and inflammation.

Summary
Interactions between cells and their neighbouring cells control many important processes in the body. The adhesion molecule E-cadherin is a major protein that controls how cells interact with one another in many epithelial tissues (e.g. breast, lung, gut). These tissues are the source of many common diseases, particular cancer and inflammation. E-cadherin is essential for these tissues to form normally, and loss of E-cadherin function contributes to disease in these tissues (especially common ca ....Interactions between cells and their neighbouring cells control many important processes in the body. The adhesion molecule E-cadherin is a major protein that controls how cells interact with one another in many epithelial tissues (e.g. breast, lung, gut). These tissues are the source of many common diseases, particular cancer and inflammation. E-cadherin is essential for these tissues to form normally, and loss of E-cadherin function contributes to disease in these tissues (especially common cancers, such as breast and lung). Understanding how E-cadherin controls normal cell function in these tissues will therefore provide key insights into how disease arises. In this study we will investigate how a protein which binds to E-cadherin, cortactin, contributes to the biological effect of E-cadherin in supporting tissue architecture. Understanding the fundamental elements of how cortactin works with E-cadherin will provide invaluable information into how cells recognize one another in health, and fail to adequately recognize each other in common diseases.Read moreRead less
MicroRNAs are small molecules that modulate the expression of most genes and so affect nearly every biological process and pathology although, they were only discovered in humans less than 10 years ago. The bottleneck in discovering the functions of miRNAs is in identifying their molecular targets, the majority of which remain unknown. We aim to comprehensively identify direct target genes of epithelial-specific microRNAs and to confirm a number of them by gene target validation approaches.

Summary
The spread of cancer to other organs involves cancer cells changing to a more aggressive state and is a major cause of cancer related death. MicroRNAs are a class of genes that control whether cancer cells become more aggressive by regulating other genes. In this project we will examine the function of a new microRNA target which controls the cancer cell aggression. The outcome will be a better understanding of how cancers spread and the identification of new therapeutic targets.
