Overview

Background

Dr Jocelyn Widagdo is a molecular neuroscientist at the Queensland Brain Institute (QBI), The University of Queensland. She received her PhD from the University of New South Wales and, after a short period of postdoctoral training at the Johns Hopkins University in Baltimore, Dr Widagdo returned to Australia in 2012 and joined the QBI, where she is currently a Senior Research Fellow at the Clem Jones Centre for Ageing Dementia Research. She leads a research team focused on uncovering the epitranscriptomic mechanisms that regulate brain function. Her work centres on how RNA modifications regulate synaptic plasticity, learning and memory. Beyond RNA, her research extends to chemical modifications of DNA and proteins, and explores how these highly dynamic molecular changes orchestrate neuronal activity and may contribute to brain disorders. Dr Widagdo’s research is supported by the Australian Research Council and was awarded a Discovery Early Career Researcher Fellowship. Through her research, she hopes to open new paths toward understanding molecular switches that support healthy brain aging.
