Christel Dorothee Hansen

I am a lecturer in the Department of Geography, Geoinformatics and Meteorology at the University of Pretoria, South Africa. I am a geomorphologist and GIS specialist, focusing on periglacial environments in the Antarctic and sub-Antarctic, as well as the high-altitude areas of mainland South Africa. My PhD focused on high-altitude and -latitude frost environments and I have extensive fieldwork experience, having spent 4 summer seasons in western Dronning Maud Land of Antarctica, one season on sub-Antarctic Marion Island, and having completed numerous fieldwork trips to the High Drakensberg of South Africa. I havealso done fieldwork in the Altai Mountains of Russia. Through my involvement in APECS and APECSSA, I have also helped organise numerous workshops, meetings, and webinars. I currently serve as President of the Southern African Association of Geomorphologists (SAAG). My research interests include cold-climate geomorphology, Antarctic landscapes and ecosystems, the Polar Regions, active layer and permafrost dynamics, thermal-moisture dynamics of seasonally frozen ground, landscape and process studies, weathering and erosion, desert environmental studies, and remote sensing.
