Postdoctoral fellows


Laura Crisp

MSN
I am studying melt inclusions in zircon, and am focussed on using the Rare-Earths (REE+Y) in zircon and the melt inclusions to interpret petrogenetic processes, and to extract the conditions, (such as temperature and oxidation state) of the melt at the time of zircon crystallisation.

Hannah Davies

GFZ
I am developing and using the Fastscape landscape evolution model initially written by Jean Braun to compute erosion rate of continental landmasses to quantify sediment flux to the continental margin and subduction zones throughout Earth history.

PhD Students


Aleksander Chugunov

UGA
I’m working on the model of the evolution of the Archean mantle composition, applying petrology and geochemistry methods to understand magmatic events from 3.27 Ga komatiites of Weltevreden Formation, Barberton Greenstone Belt, South Africa.


Julius Eberhard

Using numerical and conceptual models, I am investigating the role of climate and its interactions with erosion and plate tectonics after “Snowball Earth” events and over the course of Earth’s long-term evolution.
> Webpage


Matéo Esteban

UGA
I am interested in the origin of the Siberian trap’s meimechites (ca. 251 My) which are one of the most magnesian melts of the Phanerozoic era. I am using olivine-hosted melt inclusions to retrieve their primary melt composition and their source characteristics.
