The main focus of our research is to elucidate the cellular signals that regulate the ability of our immune system to control diseases such as cancer and inflammatory diseases. 

We have made important contributions to immunology research including the interaction of immune cells with the infectious- or tumour-derived immunosuppressive microenvironment and identification of factors that regulate immunity responses. 

Our goal is to identify new regulatory elements that prevent the immune system, particularly natural killer (NK) lymphocytes, from controlling disease progression. Our work spans the broad areas of cell signalling, immunotherapy, and inflammation, among others. 

We envision awakening the cure inside us, aiming to discover how to activate and maximise immunological responses, using the patient’s own immune system. 

Thanks to our funding, our most recent achievements elucidated the relative contribution of different immunosuppressive factors in regulating NK cell function (among other immune cell subsets) during homeostasis and disease.

Our projects use a multidisciplinary approach, bringing together contemporary techniques in cancer biology, cellular and molecular biology, pharmacology, proteomics and immunology/immunotherapy. We use cutting edge models to: mimic disease, validate our discoveries, elucidate mechanisms of action and tailor novel therapeutic approaches. Our research elucidates the cellular signalling and mechanisms regulating innate lymphocytes, and seeks to use this knowledge to develop novel therapeutic interventions for different diseases 

Our current research projects aim to: 

  • Use compuational and system biology to identify new regulatory elements in cellular signalling of immune cells 
  • Identify and understand novel immune checkpoints 
  • Tailor immunotherapies to modulate immune responses in cancer and inflammatory diseases. 
  • Development of personalized engineered immunocellular therapies 

Student projects 

We have research interests in, but are not restricted to: 

  • Systems biology to identify new regulatory elements in cellular signalling of immune cells 
  • Identifying and understanding novel immune checkpoints 
  • Tailoring immunotherapies to modulate immune responses in cancer and inflammatory diseases 
  • Development of novel pre-clinical models to mimic and study novel therapeutic targets for human disease
