Professor Belinda Medlyn is Distinguished Professor of Ecosystem Modelling at the Hawkesbury Institute for the Environment, Western Sydney University. Her research work focuses on translating information from plant and ecosystem scale experiments to develop models predicting vegetation function, particularly vegetation responses to elevated carbon dioxide, rising temperature and drought. She leads model synthesis activities at the Eucalyptus FACE experiment in Western Sydney, and has been instrumental in evaluating ecosystem models against Free-Air CO2 Enrichment (FACE) experiments internationally. Her research on stomatal conductance has drawn together the main strands of evidence about stomatal behaviour to develop a unified theory that serves as a major framework for research in this area, and her work on drought mortality led her to establish the Dead Tree Detective citizen science initiative. She was a Clarivate Analytics Highly Cited Researcher in 2018-21, and in 2019 won the Australian Research Council Georgina Sweet Laureate Fellowship.
