Dr Oon Chern Ein completed her BSc (1st Class Hons) in Biotechnology at Universiti Kebangsaan Malaysia before securing a scholarship from the Ministry of Higher Education Malaysia to further her doctorate studies in Medical Oncology in University of Oxford, United Kingdom. She then trained at Karolinska Institutet, Sweden as a postdoctoral fellow before returning to Malaysia to serve as a lecturer at Institute for Research in Molecular Medicine, Universiti Sains Malaysia. Chern is an active member of American Association for Cancer Research (AACR), a fellow of the Association of Union for International Cancer Control (AUF) and an ambassador for European Association for Cancer Research (EACR). She is also a member of the Young Scientists Network- Academy of Sciences Malaysia. In 2014, she won the Exiqon Young Scientist Award- South East Asia and was the sole recipient of the Ranjeet Bhagwan Singh Medical Research Trust Fund. Chern was selected by the Council for the Lindau Nobel Laureate Meetings to participate in the 65th Lindau Nobel Laureate Meeting in Germany in 2015. She continues to receive numerous awards for her work on novel molecular therapeutics in cancer including the prestigious L'Oreal-UNESCO for Women in Science National Fellowship in 2015 and the Union for International Cancer Control ICRETT Fellowship in 2016.

Research Interest

Dr Oon's area of research includes understanding the molecular interactions between cancer cells and the tumour microenvironment which contribute to tumour progression and therapeutic failures. Her work focuses on dissecting the molecular mechanisms conferring to chemoresistance and exploring the benefits of novel agents towards the development of new molecular targeted therapies in cancer.
