Professor Susanne Schmidt is a researcher and educator at The University of Queensland and Alexander von Humboldt fellow. Susanne has a passion for ecophysiology and plant nutrition and leads a vibrant group researching plant-microbe-soil interactions. Fundamental to applied research addresses environmental problems at the interface of ecology and agriculture.


Professor Christine Beveridge is a researcher and educator at The University of Queensland and current Future Fellow of the Australian Research Council. Christine’s research team uses advanced molecular, physiology and computer modelling technologies to understand how mobile plant signals and resources interact to control shoot and root architecture and development.


Professor Ulrike Mathesius is a researcher and educator at The Australian National University. Ulrike is interested in extending the use of beneficial microbes in agriculture. Her group is using molecular and biochemical tools to understand the signals that control the interactions of roots with symbiotic and parasitic microbes.
