Dr. Huntsman’s research has led to the development of predictive and prognostic tissue-based cancer biomarkers for ovarian cancer and a wide variety of other tumour types. His team created a blueprint for histotype specific ovarian cancer control and have been leaders in the application of novel genomics technologies to ovarian cancer. Recently, his team applied next generation sequencing technologies to ovarian cancers and discovered key mutations in granulosa cell tumours, clear cell and endometrioid carcinomas, sertoli-leydig cell tumours of the ovary and small cell carcinomas of the ovary. His team is working to determine the biologic and clinical relevance of these discoveries with a view to developing new treatment, diagnostic and prevention opportunities. Dr. Huntsman has published >300 publications, many in high impact journals such as Nature, N Engl J Med, Cell, JAMA, and Nat Genetics. He has secured over $20M of research funding as Principal Investigator plus an additional $73M as a co-Investigator. His research has attracted collaborative industry projects from Sanofi, Novartis, Astra-Zeneca, and Pfizer.
