Dr Madara Ratnadiwakara is a post-doctoral scientist working in the Cancer Genetics and Functional Genomics lab led by Professor Ron Firestein.

Dr Ratnadiwakara completed her PhD in 2015 at the John Curtin School of Medical Research- Australian National University under the supervision of Associate Professor Anneke Blackburn. She then joined the Laboratory of Dr Minni Änkö at the Monash University in 2016 as a post-doctoral research fellow. With the relocation of the laboratory, she joined Hudson Institute of Medical Research in 2018 and moved to the Cancer Genetics and Functional Genomics lab in 2022.

Dr Ratnadiwakara’s current research focuses mainly on the role or RNA binding proteins in regulating RNA processing machinaries during early development and cancer.
