Geomorphometry and mountain glaciation. Developing fundamental principles of general and specific geomorphometry (the analysis of land surface form), especially for altitude, slope and curvature values, their relationships, and scale dependence or fractal properties.

Applying these approaches to the morphology of glaciated landforms in mountainous regions, and to slopes in general, especially with use of Digital Terrain Models. Analysing and developing models for the distribution of glaciers and glacial cirques. Surveys of cirques and glaciers in British Columbia, Britain, the Alps and Scandinavia. Cirque shape and size, allometric and diverse development. Data analysis, especially directional and spatial data, and analytical thematic cartography.

Teaching interest include: Geomorphology, Glaciation & Cold Environments; Mountain Glaciation; Data analysis (level 2 & MSc in SIT); Cartography & graphics; and DEMs & Glaciation, for GeoEnv MSc.
