Professor Dixon's research interests lie primarily in the area of Critical Zone processes and landscape evolution. He is primarily interested in the nature and rates of chemical weathering in Arctic and alpine environments. Since 1990, he and his research team have worked inScandinavia, especially in Swedish and Norwegian Lapland, as well as in the Jotunheimen of southern Norway.In addition he is also interested in regolith processes in arid environments, especially in the genesis and environmental significance of relict soils.
