We contribute to research in the area of geophysics: seismology, geomechanics focusing on analysis and interpretation of nano- and picoseismicity in mining, underground research laboratories and geomechanical laboratories, as well as in the field of (induced) microseismicity and seismic network design. This sub page contains a selected list of academic papers as well as conference materials with our contribution to these fields.
