My areas of interest and expertise include broadly topics related to climatology, geomorphology, sedimentology, transdisciplinary human-environment processes (global change), and sustainablity, including sustainability education. In climatology, I am particularly interested in understanding the regional dynamics and general implications of climate change. Connections to geomorphology include aeolian processes (esp. sand dunes, wind erosion, and their climate connections) and hydrological-fluvial processes (esp. denudation, flooding). Most of my geomorphological studies take place in Lapland and Iceland. Regarding anthropogenic systems, urban climates are of particular interest, specifically spatio-temporal variations of climate and their implications to e.g., human comfort, health, road management and urban planning. My research areas span from Northern Fennoscandia to East- and South-West Africa.
