Research interests

My research primarily focuses on the earth surface processes active within glaciated and mountain landscapes. My particular research interests lie in the processes and impacts of erosion. This research is largely motivated by a wish to better understand the geomorphic and environmental impacts of climate change within these dynamic landscapes; a setting which is particularly sensitive to planetary warming.
