Professor Guillaume Tcherkez

PhD Plant Ecophysiology

I did my PhD at the University of Paris-Sud (Orsay, France) in Plant Ecophysiology (supervisor Prof. J. Ghashghaie) and then a post-doc at ANU under the supervision of Prof. Graham Farquhar thanks to the DEST scheme Endeavour Fellowship (2005-2006). Up to Dec 2014 I was Lecturer and then Professor, Head of the isotopic and metabolomics facility of the Institute of Plant Biology (University of Paris-Sud), and Junior Member of the University Institute of France (IUF). From Jan 2015, I am Professor and lab leader at ANU and since 2019, I have been Divisional Visitor at the Research Institute for Horticulture and Seeds (INRAe Angers, France).

Convevor of the International Course on Stable Isotopes - Isotopomics (joint course with the University of Nantes), ANU BIOL3110/6110

This course deals with stable isotopes, across different areas, from biology to earth sciences, environmental studies and medicine. In this course, students are taught the importance of isotopes in a variety of applications and how they can be used for basic science, environmental monitoring, etc. This course involves different universities (from France, Japan, Poland and Australia) in an international teaching initiative originally supported by the Region Pays de la Loire (France) via the grant PLAISIR. There are shared lectures and the course is recognized by the University of Nantes through a Memorandum of Understanding. Students are prepared to the broad area of isotopics, which carries job opportunities in different branches of a modern economy: authentication, detection of doping, food traceability, etc. This course is offered to both undergraduate and postgraduate students, and is adapted not only to students committed to a curriculum in Biology but also Earth Sciences and Chemistry.
