Georg F. Zellmer received his PhD from the Open University (UK) in 1999, and subsequently worked as research fellow at the University of Bristol (UK), the Lamont-Doherty Earth Observatory (USA), the University of Hawaii (USA), and Academia Sinica (ROC). As Massey University since 2013, Professor Zellmer investigates the timescales of magmatic processes, volatiles in subduction zones, and other fundamental aspects of igneous systems. At present, he devotes time to the development of a spinel-structured oxide hygrometer for a range of applications in the Earth and Planetary Sciences. Professor Zellmer is Acting Executive Editor of Journal of Petrology.

Papers team-taught since 2014:
I consider doctoral students as junior colleagues, who I can support through my many years of research experience. Within my team, all members are benefitting from the shared enthusiam for pushing the frontiers of scientific understanding in the Earth and Planetary Sciences, supported by a combination of bright ideas and hard work.
My research interests include all areas of igneous petrology and geochemistry, with a focus on microanalytical techniques to answer large-scale questions on the rates of magmatic processes, and how volatiles and other factors impact magma generation, ascent, storage, and volcanic eruption. I am striving for integration of several geoscientific disciplines to gain reliable insights, in collaboration with domestic and international colleagues, and funded through domestic and international research grants.
I am operating under the Volcanic Risk Solutions policy to accept into my team only those candidates who are fully funded through doctoral scholarships and are thus able to devote their time and attention to conduct research. However, I encourage all of my students to also participate in the activities offered by the Graduate Research School, which support doctoral candidates in developing into independent researchers, becoming successful within and beyond their specific research project.
Due to my involvement in international collaboration, I am generally away from Massey for a few months per year, often accompanied by some of my doctoral students, who are typically co-supervised by international colleagues. For this reason, I am normally not available for Masters supervision, although I can make exceptions for particularly promising candidates, who are committed in their ambition to move on to doctoral studies following their MSc graduation.
I encourage potential candidates to contact me by email to discuss research projects and research funding that may be available, especially those who have managed to secure their own funding and have ideas for conducting interesting research projects in my field, which I might be able and happy to support.
