The HPx-eos and THERMOCALC software are developed by an international team of Earth scientists.
The core development team:

Eleanor Green. Eleanor is Senior Lecturer in Computational Petrology at the University of Melbourne. She develops the HPx-eos and their applications, and guides the ongoing expansion of THERMOCALC. She also develops and maintains this website. Send her a message using the contact form (multiple recipients).

Roger Powell. Roger, who also goes by RP, is Emeritus Professor of Earth Sciences at the University of Melbourne. He leads the development of THERMOCALC, and is closely involved in much else to do with the HPx-eos and their applications.

Tim Holland. Tim is Emeritus Professor at the University of Cambridge. He leads the development of the internally-consistent dataset of end-member thermodynamic properties, and other key steps in the development of the HPx-eos and their applications.
Other close collaborators, who develop and test aspects of the modelling:

Johann Diener. Johann is Associate Professor of Metamorphic Petrology at the University of Cape Town. He applies the HPx-eos via THERMOCALC and is involved in their development.

Katy and Pudding Evans. Katy and Pudding developed the sulphide and sulphur-bearing end-members in version 6 of the Holland & Powell dataset. Pudding is pictured, while Katy, who is Associate Professor at Curtin University, did most of the actual modelling.

Owen Weller. Owen is Associate Professor at the University of Cambridge, with interests spanning metamorphic and igneous petrology. His current focus on the petrogenesis of alkaline igneous systems has driven HPx-eos development into this area.

Richard White. Richard is Professor of Earth Sciences at the University of St Andrews. He tests and applies the HPx-eos via THERMOCALC.
