Dr Vicky Tsai
Dr Vicky Tsai received her PhD from the University of Queensland, followed by postdoctoral training at Academia Sinica in Taiwan, where she led a study identifying a key neuroinflammatory mechanism driving amyloid plaque accumulation. She later joined Prof. Sam Breit’s team in the Inflammation and Cytokine Biology Program at St Vincent’s Centre for Applied Medical Research, where her research focus shifted to neuronal circuitry underlying appetite regulation and metabolism.
Dr Tsai played a central role in the NHMRC-recognised studies on GDF15/MIC-1 (Project Grant 1057910; NHMRC Ten of the Best Projects 2011), where she defined its signalling pathways and demonstrated its central role in cachexia, appetite control, and metabolic regulation. Her work has significantly contributed to the development of therapeutic strategies targeting GDF15 inhibition for the treatment of cachexia, now validated in Phase II clinical trials.
