Research Focus

My research focuses on kinase biology and how kinase signalling pathways are hijacked in cancer. We combine computational biology with proteomics and cell biology to uncover novel ways to target these dysregulated networks.

Research

Kinases are attractive therapeutic targets for cancer. Approximately 25% of the known 535 kinases are associated with cancer through mutation, overexpression or aberrant signalling. However, the majority of therapies targeting kinases in cancer patients fail, due to development of resistance, or toxicity. We are working to develop new approaches to target cancer kinases to overcome these limitations.

We have described a novel mechanism by which kinase substrate specificity is regulated. Modification of the kinase activation loop by phosphorylation or mutation can alter substrate specificity. In cancer, this can lead to the rewiring of signalling pathways to promote oncogenic properties. How substrate specificity is determined, particularly relating to activation-loop modification is a hitherto unexplored niche which will provide new insights in the targeting of kinases in cancer.

This now provides an exciting opportunity to significantly advance understanding of the fundamental biology of kinase regulation. These new insights will enable the discovery of previously unknown or undefined signalling nodes and establish a route to developing new kinase inhibitors for personalised cancer therapy through the delivery of a high-resolution understanding of kinase regulation and dysregulation in cancer.

Biography
I completed my Bachelor of Science at the University of Queensland, Australia, before going on to an Honours program at the Queensland Institute for Medical Research. I attained my PhD from the University of Queensland, studying the role of MAP kinase signalling in the cell cycle and mitosis with Professor Brian Gabrielli. After completing my PhD, I moved to London to start a Postdoctoral Fellowship with Professor Peter Parker initially at the CRUK London Research Institute, Lincolns Inn Fields and then moving to the Francis Crick Institute when it opened in 2015.  Here I investigated the genome protective role of the kinase PKCε, in the cell cycle. In 2019, I commenced a postdoc with Dr Sarah McClelland here at Barts Cancer Institute, researching chromosomal instability in High Grade Serous Ovarian Cancer and started my own independent laboratory at BCI in July 2020.
