Research | Current

My research interests are concerned with the molecular mechanisms that underlie cell differentiation, with a focus on microRNAs. My main interest to date has been on two clinically relevant cell types – T cells and stem cells.

Being able to control the differentiation status of a cell is critical to successful immunotherapy protocols, where patients’ immune cells (T cells in this case) are used to treat their own cancer. Therefore, in collaboration with Prof. Rod Dunbar and his team (SBS, University of Auckland) we are examining the role miRNAs play in T cell differentiation. In collaboration with Prof. Tudor Fulga and his team at Oxford University, UK, we are also applying genome editing techniques to these cells in order to create "optimal" T cells for use in immunotherapies..

In the field of stem cell biology, being able to control the differentiation potential and status of human adipose derived stem cells (ASC) will be critical to the success of therapies using these cells. By understanding these processes at the molecular level we aim to develop methods to generate stem cells with maximum differentiation potential for use in a clinical setting. This work is in collaboration with Dr. Vaughan Feisst (SBS, University of Auckland).

More recently we have begun to turn our attention to using genome editing tools, specifically CRISPR/Cas9, to create patient-specific genome-edited skin as a potential treatment for people with the fragile skin condition known as Epidermolysis Bullosa. This is a collaborative project with Prof. Fulga from Oxford University, UK,  Dr. Diana Purvis from Starship Hospital, Auckland and Dr. Vaughan Feisst from SBS.
