dipl. Natw. ETH, geophysicist. Founder and managing director

Walter FreiWalter Frei started his professional career as a merchant navy seaman in 1957 and, having served as chief officer on supertankers, fruit carriers, gas tankers and ore carriers, he started studying geophysics in 1971 which he completed with a diploma degree in 1975. He then spent the following six years with Shell in the Netherlands and in Irian Jaya (Indonesian New Guinea) working in seismic data acquisition, processing and well log data analysis. After moving to Switzerland he then held posts as a programmer developing wire line data evaluation software for a logging contractor, and as a part time assistant professor at the Swiss Federal Institute of Technology, lecturing seismic methods in civil engineering between 1982 and 1999. He was assistant director for the Swiss National Science Foundation Programme 20 (Deep Structures of the Swiss Alps) from 1985 until 1991 and as such responsible for the acquisition and processing of reflection seismic data. Walter co-founded GeoExpert in 1988 and has since then been its managing director.

Romain Bauer

MSc in geology, University of Lausanne, geologist, member of the board

Romain BauerRomain finished his studies in geology at the University of Lausanne (UNIL) in 2011. During his studies, he specialized in the field of geophysics and wrote his Master thesis on seismic reflection on the Lake Geneva. This thesis enabled him to be familiar with acquisition, processing and interpretation of seismic data. After graduating he worked as a permit man for oil exploration in Switzerland. He then worked as an assistant at the Institute of Geophysics of the UNIL where he lectured and collaborated in scientific research projects. Romain joined GeoExpert in July 2012 and is in charge of the Geneva branch office since August 2015. He is GeoExpert’s representative for French speaking countries.
