Description

The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post‑docs, post‑graduates or apprentices. Altogether, PSI employs 2300 people.

Postdoctoral Fellow in Thermodynamic Modelling and Equations of State

Your tasks

• 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

Your profile

• PhD degree in geochemistry, physical chemistry, chemical engineering, computational science or a related field, with background in chemical thermodynamics
• Experience with scientific programming in Python and/or C++ or demonstrated ability to develop scientific software including the use of 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
