The majority of deaths from cancers are due to metastasis. MicroRNAs are gene regulators involved in shaping cellular properties and are known to control metastasis. My work will lead to understanding how the production of microRNAs in cancer cells is controlled, what the major functions of microRNAs are in cancer cells and the discovery of pathways that may be amenable to new forms of therapeutic intervention in cancer.

Summary
Epithelial tissues, such as the lung, fundamentally protect the body from its external environment. For this, they must detect and respond to danger. My work has discovered a new biological system where cells monitor changes in mechanical forces as a sign of danger. Diseases such as inflammation and cancer occur when this detection system fails. This Fellowship builds on my lab’s pioneering work to understand how force is used to sense danger, and how disease occurs when it goes awry.
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.
I am a cell biologist/geneticist focusing on understanding tumourigenesis. Cancer is a multigenic and complicated disease, involving interactions between the tumour and normal tissue. I use the genetically tractable model organism, the vinegar fly, Drosophila, to model cancer in situ and identify novel genes that drive cancer. My 5 year career plan is to use the Drosophila system to model cooperative tumourigenesis in epithelial and brain tissues and translate this to human cancer.
