My research focuses on how the intricacies of cell-cell communication can impact the process of blood cell development or haematopoiesis. I am specifically interested in an intracellular pathway called the JAK/STAT pathway which responds to messenger proteins called cytokines. Haematopoiesis is regulated by the activity of specific cytokines that signal for the differentiation of haematopoietic stem cells and their downstream specific lineages. Any dysregulation in this signalling can cause dysfunction of haematopoiesis resulting in disease.

I completed my PhD under the supervision of Prof. Alister Ward looking at various mutations impacting the JAK/STAT pathway and identifying how these mutations can impact haematopoiesis as well as overall immunity.

Following my PhD, I joined SVI as a Postdoc in the Stem Cell Regulation Unit, expanding my research into haematopoietic stem cells (HSC) with a specific interest in the pathogenesis of Myelodysplastic Syndrome (MDS). We utilise a newly developed mice model to help delineate the molecular characteristics of MDS, such as HSC activity and JAK/STAT signalling. By characterizing these mechanisms, we are then able to test various therapeutics that can potentially alleviate the development or progression of MDS. We hope to use this model to improve treatment outcomes and develop novel therapies for patients suffering from MDS.
