Postdoc: Thermodynamics & EOS Modeling in Geochemistry

PSI; Villigen; Remote; CHF 120,000 - 160,000; Full time

Job summary

The Paul Scherrer Institute (PSI) seeks a Postdoctoral Fellow in Thermodynamic Modelling and Equations of State to develop and apply advanced models for hydrothermal systems. You will work on experimental data interpretation, database development, and contribute to open-source tools with researchers at PSI and New Mexico Tech.

You will collaborate on publications and present results at international conferences, contributing to interdisciplinary research in geochemistry and computational

Qualifications

• PhD in geochemistry or related field with background in chemical thermodynamics.
• Experience with Python and/or C++ for scientific programming, or ability to develop scientific software including AI programming support.
• Experience with non-linear least-squares fitting, parameter optimisation and uncertainty estimation.
• Experience with geochemical modelling codes (GEMS, PHREEQC, SUPCRT / SUPCRTBL, Reaktoro, other), the HKF model or density-based EoS and with thermodynamic database development is an advantage.

Responsibilities

• Develop and apply equations of state and activity models for modeling fluid-rock interaction in hydrothermal systems and the mobility of critical elements
• Compile, evaluate and interpret experimental thermodynamic data and use physical, statistical and/or machine learning methods to estimate missing model parameters
• Contribute to the development and extension of internally consistent thermodynamic databases (e.g. Mines thermodynamic database)
• Contribute to the GEMS / ThermoEcos open-source ecosystem (ThermoFun, ThermoExp, GEMS, GEMSFITS)
• Collaborate with researchers at PSI and New Mexico Tech (USA), contribute to publications and present results at international conferences
