Researcher biography
Jocelyn Widagdo received her PhD in 2011 from the University of New South Wales. After a short period of postdoctoral training at the Johns Hopkins University in Baltimore, USA, Dr Widagdo returned to Australia in 2012 and joined the Queensland Brain Institute, the University of Queensland, where she is currently a Research Fellow at the Clem Jones Centre for Ageing Dementia Research. Her research aims to understand how the process of synaptic plasticity, learning and memory are underpinned by dynamic regulation of DNA, RNA and proteins, and consequently, how they contribute towards the pathophysiology of neurodegenerative diseases and neuropsychiatric disorders. Her works were published in journals such as The Proceedings of the National Academy of Sciences USA, Journal of Neuroscience and Cell Reports, and has attracted more than 1500 citations. Dr Widagdo was awarded a Discovery Early Career Researcher Fellowship (2017-2020) and a Discovery Project grant from the Australian Research Council (2023-2025).
