My areas of interest and expertise include broadly topics related to climatology, geomorphology, sedimentology and transdisciplinary human-environment processes (global change). 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.
My typical teaching year consists of the following courses taught either by myself or jointly with other teachers:
MAAN6091 Basics of Geography (jointly), (lecture course)
MAAN6151 Geomorphology (lecture course)
MAAN6153 Climatology (lecture course)
MAAN6570 Climate.now – Basics of climate change (online course; responsible teacher)
MAAN7052 Geography colloquium (responsible teacher)
MAAN7141 Geography research course (responsible teacher) (lectures, field class, laboratory work)
MAAN7354 Global change (lectures, literature, group work, field excursion)
MAAN7741 Systemschange.now – Systems thinking in Global change research (online course; responsible teacher)
