Research

​​Themes in my research include inflammation, immune responses against bowel cancer and its metastasis. I have a focus on members of the C/EBP transcription factor family, including how they regulate SWI/SNF suppression complexes, how they interact with other transcription factors, and how they control immune cell phenotypes. A key question is how they contribute to the immune evasion of cancers, particularly with respect to their cooperation with inhibitory immune checkpoint proteins. In addition, I have a focus on the prognostic value of single nucleotide polymorphisms (SNPs) altering these processes. Additional layers include 1. How interleukin 6 works in IBD and how this is affected by gene variation; 2. The roles of non-coding RNA (lncRNA) transcripts; and 3. How C/EBPβ operates in the context of wider stress signalling. A key goal is to identify ways that additional drugs can be combined with immune checkpoint inhibitors to improve their utility.​
