Claudia Keitel

Claudia Keitel is an Associate Professor in the BIO Department at The University of Sydney. Her research interests include plant physiology, agro-ecosystem function and prediction, crop and pasture biochemistry and physiology, ecological physiology, fertilisers, ecology, plant biology, and crop and pasture production. She has worked extensively with stable isotopes and has conducted research on environmental effects on tree physiology. Her career has included postdoctoral fellowships at the Australian National University and the University of New South Wales, and she joined The University of Sydney in November 2008.

Claudia Keitel, affiliated with the University of Sydney, focuses on isotopes and plant physiology. Her research explores the role of stable isotopes in understanding plant carbon and water relations, including carbon and oxygen isotope composition in phloem sap and its relation to stomatal conductance. She investigates carbon allocation, isotope fluxes, and the impact of environmental factors such as climate change and drought on plant physiology. Her work also examines nitrogen and phosphorus use efficiency in crops and the effects of nutrient addition on microbial processes. Keitel's studies contribute to understanding plant responses to environmental stress and the physiological mechanisms underlying carbon and water dynamics in ecosystems.
