Zeno Heilmann received a master's degree in Geophysics from the University of Karlsruhe, Germany, in 2002. From 2002, he did a PhD under the supervision of Prof. Peter Hubral. During this time, he was a research associate of the WIT Consortium. He took part in the development of a CRS-stack-based time-to-depth imaging workflow, was responsible for its application in a geothermal energy project, and worked on an extension of the CRS stack software for rugged topography. In 2007, he received a Doctorate, awarded magna cum laude. In September 2007, he started a position as a researcher in the Imaging & Numerical Geophysics Group of CRS4. From 2007 to 2014, he took part in an industrial project, working on new seismic imaging methods, coherent noise removal, and full waveform inversion. From 2008 to 2011, he was also engaged in a project developing a multidisciplinary grid-infrastructure for geoscience. From 2015 to 2017, he was working in the SmartGeo project, developing a cloud portal for seismic data-processing. From 2017 to 2021, he applied geoelectrical methods in two projects targeting environmental geophysics and precision agriculture. From 2021 to 2023, he took part in an industrial project aiming at designing a production facility for green hydrogen and in a project aiming at developing an IoT platform for intelligent solar charging of electric cars. Since 2023, he collaborated on a project using satellite drone and ground resistivity data for archaeological research.

Gian Piero Deidda was born in Jerzu, Sardinia, Italy. He is an Associate Professor of Applied Geophysics at the Department of Civil and Environmental Engineering and Architecture (University of Cagliari). He graduated with honors in Mining Engineering at the University of Cagliari in 1989, with a thesis about a gravimetric survey carried out in the geothermal area in Sardinia (Italy). In 1993, he was awarded a Certificate of Graduation in Seismic Data Processing from OGCI, Inc. In 1998, he patented a new seismic sensor with increased response to SH waves: Geophone and method for the study of elastic wave phenomena (ITTO98A000030, WO9936799, CA2318036, AU199918853B2, US6366537B1). He is a member of SEG, EAGE, and EGU. His main research interests span from electromagnetic to seismic methods for geotechnical, environmental, and hydrogeological applications. Currently, in collaboration with the Department of Mathematics and Computer Science (University of Cagliari), the Imaging and Numerical Geophysics group of CRS4 (Sardinia, Italy), the Department of Geosciences (University of Padova), and the Realtimeseismic company (France), his research activity focuses on nonlinear inversion of frequency-domain electromagnetic data, full-waveform inversion of seismic and radar data, near-surface seismic imaging using the CRS stack and the PSDM, and the development of innovative and fast seismic data acquisition procedures using fiber-optic distributed acoustic sensing systems.
