Research outline

I am an experienced researcher based at the Children’s Cancer Institute, where I lead a team of postdoctoral researchers and students focused on the childhood solid tumour neuroblastoma. Children with high-risk neuroblastoma frequently relapse with incurable, drug resistant disease, resulting in long-term survival rates below 50%. We seek to understand the biology of neuroblastoma and to improve patient survival rates through:

  • Identifying molecular mechanisms underlying drug resistance
  • Developing small molecule inhibitors targeting drug resistance mechanisms, with particular focus on multidrug resistance proteins
  • Developing improved pre-clinical testing models for high-risk neuroblastoma, including patient-derived xenograft (PDX) models and models of metastatic disease
  • Modelling personalised medicine strategies, including molecular profiling and ex vivo drug sensitivity screening

My team applies high-throughput drug screening, genomic analysis, mouse models, cell biology and tissue-culture based approaches to the study of drug resistance mechanisms, personalised medicine and new drug development in high-risk neuroblastoma. Our high-risk neuroblastoma research is published in leading journals, including JNCI, Cancer Res, Oncogene, Eur J Cancer, Nature Reviews Cancer and Science Translational Medicine.
