My research is focused on electromagnetic (EM) methods for geophysical prospecting, which aim at studying the electrical conductivity distribution of the subsurface. I am especially interested in the application of natural-source electromagnetic methods such as magnetotellurics (MT) for geothermal exploration.
One aim of my work is to improve MT surveying in densely populated regions, where noise signals produced by environmental (manmade) sources make MT challenging. Aside from conducting MT field studies I’m working on improving 3-D interpretation of large MT datasets predominantly from the East African Rift. During my doctoral studies in 2012 I lead a MT project at the Aluto-Langano geothermal field in Ethiopia. Since then I’m involved in geothermal exploration projects in Ethiopia and work in close collaboration with industry. Currently I’m leading the r4d-funded project “Development of a geoscientific framework for geothermal exploration and energy utilization in Mongolia”.
Besides exploration methods such as magnetotellurics I am investigating the capability of using unmanned aerial vehicles (UAV) for airborne EM, geomagnetic mapping and thermographic imaging.
