I am interested in mechanisms of Late Quaternary climate change. In particular, the causes of the 100,000-yr glacial cycles of the past million years, and the abrupt climate switches that brought them to a close, remain fundamental outstanding problems. I am also interested in the underlying causes of natural climate variations over the Holocene, and their associations with the rise and fall of civilizations. The effects of ice ages, abrupt climate change, and Holocene climate variability have been imprinted on the landscape by Earth's mountain glaciers, ice sheets, and pluvial lake systems. I am attempting to construct the evolution of these climate switches by developing precise chronologies of glacier and pluvial lake activity in the middle latitudes of the polar hemispheres. I use surface-exposure and radiocarbon dating techniques to construct chronologies of glacial landforms that mark past extents of mountain glaciers and ice sheets. Working together with Sean Birkel, I employ geometrical snowline reconstruction and glaciological modeling techniques to derive quantitative paleoclimatic information from glacier landforms. We are interested in how abrupt climate anomalies are transmitted between the hemispheres during glacial terminations, and more recently during Medieval time and the 'Little Ice Age'.

As an earth scientist, I aspire to provide a contribution to the comprehension of oceanic hotspots, ocean island systems, volcanic/igneous systems, the evolution of volcanic landscapes and the link between surface processes and deep mechanisms. I am particularly committed towards a multidisciplinary approach combining direct geological observations, geomorphology, isotope geochronology, geophysical imaging, numerical and analogue modeling, and with a strong physical footing on the geological record.

My main research interests include Quaternary and glacial geology, paleoclimatology, ice sheet dynamics, limnogeology, and using cosmogenic surface exposure dating to obtain chronologies for glacial and ice sheet fluctuations in South America, New Zealand, Arctic Canada, and Alaska. I have worked in eastern Maine, Arctic Canada, South America, and in New Zealand.

My research incorporates glacial geoology and cosmogenic geochronology methods to reconstruct late-Quaternary and Holocene climate behaviour. Specific interests include palaeoclimate of the tropical Andes, causes of late-glacial abrupt climate events, and the future evolution of tropical glaciers and hydrology. My work also concerns past, present, and future stability of the West Antarctic Ice Sheet, as well as palaeoclimate-archaeologic links in the high Andes.
