Erika Luck was born in Leipzig, Germany in 1956. She received her diploma in Physics at the University of Leipzig in 1979 and her PhD in geophysics in 1982 (also at the University of Leipzig). From 1982 to 1991 she worked in the field of ‘deep seismic sounding’ at the Central Institute of Physics of the Earth at the Academy of Sciences in Potsdam, Germany. In 1992 she joined the University of Potsdam as a researcher. At this time she changed her topics and started research into the application of geophysical methods for the shallow subsurface. Between 1996 and 1997 she took part in the DEKORP-experiment ‘BASIN 96’ at the GFZ Potsdam (GeoForschungsZentrum). She went back to the University of Potsdam in 1997 and continued her studies in the field of applied geophysics. Her special interests are in near-surface investigations for archaeology, agriculture and soil sciences. Martin Muller has experience in geophysics, both in education and in research, that covers a broad range of applications from hydrogeophysics, environmental geophysics, geotechnical applications, civil engineering and volcanology. He performed research with geophysical methods ranging from electromagnetics, DC-geoelectrics, magnetics, gravity, seismics, ground-penetrating radar to nuclear magnetic resonance (NMR). His latest projects dealt with the application of geophysics in the saturated and the unsaturated zone, namely in agriculture and soil sciences, to assess water content and moisture dynamics. He studied geophysics at the University of Cologne, Germany and received his diploma for a thesis on magnetotellurics. In Cologne he continued with a PhD thesis on the application of electromagnetic methods to volcanoes, namely Mt. Merapi, Indonesia and Mt. Vesuvius, Italy. From 2000 until 2006 he was assistant professor at the Department of Applied Geophysics of the Technical University Berlin (TUB), Germany, as head of the rock physics laboratory and lecturer on petrophysics and well logging. During his years at TUB, he was also a project leader in projects dealing with the integration of geophysical techniques to derive the water content in soils and application of geophysics in agriculture. During the winter of 2006/2007, he was guest professor for applied geophysics and hydrogeophysics at the University of Vienna, Austria.
