Following my PhD studies in developmental haematopoiesis with Professor Alexander Medvinsky at the University of Edinburgh, in 2008 I moved to The Walter and Eliza Hall Institute (WEHI) to undertake a postdoc in the laboratory of Professor Doug Hilton.

In 2011, I started my own laboratory at WEHI with a consistently innovative research program focused on the biology of blood production and function. As an independent laboratory head, I have developed a track record of securing competitive research funding, providing an exceptional learning experience for my research students, career progression for my team members, and publishing high quality research in top scientific journals.

In brief, my research team uses cutting edge imaging, clonal tracking (cellular barcoding), genomics technologies, and functional assays (in vivo and in vitro) to tackle long-standing questions about the biology of blood production. My current research strategy incorporates commercial and translational elements to complement my discovery research program. We have a growing emphasis on the application of our new knowledge to understand and target diseases including thrombocytopenia and neonatal stroke.
