Ririk Sulistyaningsih

Ririk Sulistyaningsih is a Doctor of Philosophy (PhD) candidate in Biological Sciences at the Institute for Marine and Antarctic Studies (IMAS), University of Tasmania (UTAS), in partnership with CSIRO and the National Research and Innovation Agency (BRIN). Her research focuses on developing and validating integrated approaches to estimating the age and assessing the population structure of yellowfin tuna (Thunnus albacares) across the Indo-Pacific region. She combines conventional ageing techniques using otoliths and dorsal spines with molecular biology, epigenetic ageing, and machine learning approaches to improve understanding of tuna biology, population dynamics, and fisheries management. With extensive experience in fisheries research, monitoring, and management in Indonesia, she contributes to strengthening Indonesia–Australia scientific collaboration and supporting sustainable tuna fisheries management.
