Research

​My research programme is currently focused on transcriptional and translational controls on gene and protein function relevant to cancer progression, and the crossover between the seemingly separate areas of energy metabolism, cancer associated inflammation, and metastasis. I have a special interest in colorectal cancer, but also cancers of the skin, breast, and ovaries. My work loosely centres on the pivotal actions of the C/EBP family of transcription factors, and explores how these may switch from anti-cancer suppressors to metastasis-driving oncogenes. In this context, I am exploring the applicability of drugs used in metabolic diseases e.g. diabetes and obesity, for re-purposing in cancer treatment. In addition, I am examining the contributions that non-coding RNAs make to these processes, and performing large scale genomic studies to identify genetic features that alter the way cancers progress in different people. My overall aim is to improve cancer prognostication and treatment strategies.​
