Abstract
Sarah Kwong explored innovative approaches for age determination in the crow-nof-thorns seastar. She developed the first epigenetic clock for this species and advanced understanding of its telomere dynamics. Her work establishes the foundation for an essential ageing tool for outbreak management and marks a significant step forward in invertebrate age determination.
