Dr. Simon Chu completed his PhD at Prince Henry’s Institute (now Hudson Institute of Medical Research) in 2005. His studies focused on the roles of the estrogen receptor in the pathogenesis of a subset of ovarian tumours, and in particular, the impact that molecular signalling pathways of the cell have on this receptor. After gaining his PhD, Dr. Chu continued his work at PHI, examining the consequences of blocking this mechanism using new therapeutic compounds to explore whether this might lead to a new chemotherapeutic approach to treating this disease.
In 2007, Dr Chu took up a postdoctoral position at the Pasteur Institute in Cambodia, where he helped develop a new molecular technique to investigate the incidence of exposure to avian influenza in the human population in that country.
On his return to Australia in April 2009, Dr Chu re-joined PHI as the Ovarian Cancer Research Foundation (OCRF) L’Oreal Paris Australia Research Fellow. His work focuses on the underlying causes of the more common type of ovarian cancer, as well as the less common granulosa cell tumour of the ovary. He is currently investigating an exciting potential therapeutic option for treating these cancers, using a combination treatment that targets two important biological pathways in the cancer cells. This presents a new chemotherapeutic approach for the treatment of ovarian cancer.
Simon’s research is focused on the causes of ovarian cancer. Although ovarian tumours are generally thought to arise from the cells on the surface of the ovary, there is increasing evidence that up to three quarters of ovarian serous cancers may originate from the fimbrial epithelium at the ends of the fallopian tube, adjacent to the ovary. His focus is thus on understanding the origins of these types of ovarian cancer.
A better understanding of the origins of ovarian cancer is a key aspect in the joint quest of OCRF and Hudson Institute of Medical Research towards an accurate and widely available early detection test for ovarian cancer.
