Assistant Professor (Geography)


My research focuses on how changes in climate are reflected in glacial landscapes. The causes of Earth's ice ages and their abrupt terminations are still uncertain, but are key to understanding our climate system and its capacity for (sometimes rapid) change.

Glaciers are highly sensitive to changes in climate. I study the traces that glaciers leave on Earth's surface as they grow and decay, and use these markers to reconstruct the timing and extent of past glacial fluctuations in regions around the globe. My goal is to use glacial-geomorphic records to understand the linkages between climate and glaciation, and to learn more about Earth's climate system in the past, present, and future.

This work involves detailed surface mapping, geochronology (surface-exposure dating, radiocarbon), and synoptic assessment of palaeoclimate and geomorphic records.

My research relies heavily on field work, and includes sites in Ireland, Iceland, Peru, Uganda, Greenland, and in the Antarctic.
