Open-Source Software Webinar: pyGIMLi

19 March 2024
10:00 AM (CDT)

In this webinar, we introduce you to pyGIMLi, an open-source software for Geophysical Inversion and Modelling. After giving some general information on pyGIMLi, we will demonstrate its potential by inverting field ERT data through adding increasing complexity using Jupyter Notebooks. It starts with simple raw data analysis and geometries to more complex settings, time-lapse and induced polarization. We demonstrate the capability of pyGIMLi take to control by different regularization schemes, region-specific settings, limits and petrophysical constraints, and incorporating additional data like structural boundaries and point data. We provide material for further reading and playing.

For the preparation of users, we have created a github repository, where you find installation instructions, backgrounds, different materials and references on

Speaker Bios

Thomas Guenther

Thomas Günther is a geophysicist and senior researcher at the Leibniz Institute for Applied Geophysics in Hannover, Germany. He received a PhD in 2004 at the Freiberg University of Mining and Technology, where he and Carsten started creating open-source software for the scientific community. Initially focusing on Electrical Resistivity Tomography and Induced Polarization, his interest broadened, covering the whole range of electromagnetics and other methods, aiming at subsurface characterization through modern joint inversion and time-lapse approaches. Current projects deal with electrical and electromagnetic methods for mineral or groundwater. Together with other colleagues, he initiated several spin-off software packages for dedicated purposes.

Florian Wagner

Florian Wagner is a full professor in Applied Geophysics at RWTH Aachen University, Germany. His research focusses on the development of multi-physical imaging and monitoring approaches for the quantitative characterization of geological reservoirs and the shallow subsurface. After receiving his PhD on the topic of 3D cross-hole geoelectrical monitoring of CO2 storage reservoirs from ETH Zurich in 2016, he has worked as a postdoctoral researcher in hydrogeophysics at the University of Bonn and as a guest scientist in cryogeophysics at Berkeley Lab before he joined RWTH Aachen University in 2019. Florian has been contributing to the development of the pyGIMLi open-source library since more than 10 years.

Carsten Rucker

Carsten Rücker is a geophysicist and now researcher at the Federal Office for the Safety of Nuclear Waste Management in Berlin, Germany. After receiving his PhD in 2010 at the University of Leipzig he joined the Technische Universität Berlin as postdoctoral researcher until 2019, where he is still a lecturer. His research focus initially on Electrical Resistivity Tomography where he early started to distribute his work as open-source software. With Thomas, he has been a developer of pyGIMLi from the very beginning on. His current research focus switched to the development of simulation tools for thermo-hydro-mechanical coupled processes in the subsurface.
