Post-Doctoral Researcher – AgrogeophysicsResearch Interests
My current research is focused on the use of Geophysics to help answer questions in Agriculture. At the moment, this involves the mapping and monitoring of Peaty soils using a variety of ground and airborne geophysical techniques.
In particular the use of ground based Electromagnetic induction techniques, where we measure the electrical conductivity of the soil layers, and the use of Drone based Radiometric data, measuring the natural environmental radioactivity are my main tools. Both give insight into the spatial distribution of soil physical properties.
