Richard Gloaguen - Head of the Exploration Technologies Division at the Helmholtz-Institute Freiberg for Resource Technology

Richard received the Ph.D. degree “Doctor Communitatis Europae” in marine geosciences from the University of Western Brittany, Brest, France, in collaboration with the Royal Holloway University of London, U.K., and Göttingen University, Germany, in 2000.

He was a Marie Curie Post-Doctoral Research Associate at the Royal Holloway University of London from 2000 to 2003. He led the Remote Sensing Group at University Bergakademie Freiberg, Freiberg, Germany, from 2003 to 2013. Since 2013, he has been leading the division “Exploration Technology” at the Helmholtz-Institute Freiberg for Resource Technology, Freiberg. He is currently involved in UAV-based multisource imaging, laser-induced fluorescence, and non-invasive exploration.

His research interests focus on multisource and multiscale remote sensing integration.


Sandra Lorenz - Head of the Processing Group within the Division of Exploration Technologies of the Helmholtz-Institute Freiberg


Graduated from TU Freiberg in 2014, holding an MSc degree in Economic Geology, Sandra is a researcher at the Helmholtz-Institute Freiberg for Resource Technology since 2014. She received the Ph.D. degree “Doctor rerum naturalis” in Geosciences at the Technical University Bergakademie Freiberg, Germany in 2019.

Her research focus lies on UAV-based, terrestrial and lab-scale (hyper) spectral imaging for non-invasive mineral exploration, in particular multi-source data processing and integration.
