Research interests

My research interests focus on understanding the pattern, dynamics and timing of past glacial events, principally through the examination of annually-layered (varved) sediments deposited in former glacial lakes. Specifically, my interests lie in the macro- and microscale analysis of glaciolacustrine varves to obtain high-resolution (sub-annual to centennial scale) palaeoenvironmental information and precise chronologies with which to frame past glacier and climate dynamics.


Current Research 

The timing and rates of glacier response to Late Pleistocene climate change in Central Patagonia (Ph.D)
This project aims to improve our understanding of the rates and timing of the last deglaciation of the North Patagonian Icefield (NPI) by examining the landforms and sediments of the Lago General Carrera (Chile) / Lago Buenos Aires (Argentina) basin. In particular, annually-laminated, or varved, glaciolacustrine sediments will be used to reconstruct the rate of glacier recession at annual to decadal scales, and to infer catchment and glacier dynamics during deglaciation.
Previous Research
Assessing the potential of X-ray computed microtomography for three-dimensional analysis of Quaternary laminated lacustrine sediments (M.Sc Dissertation) Supervisor: Dr Adrian Palmer  
Studies of laminated lacustrine (lake) sediments typically make use of 2D research approaches (e.g. thin section micromorphology). Whist highly effective, these methods lack ’true' 3D information. Therefore, this research explored the potential of X-ray computed microtomgraphy (μCT), a rapid, non-destructive and wholly 3D analysis technique, for studies of glacial varves. The method was effective for measurements of varve thickness and number, and enabled quantitative assessments of internal ('within-sample') varve thickness discrepancies. Through the creation of 3D volume renderings (i.e. 3D computer models) μCT also allowed novel insights at a range of scales, for example, the ability to detect potential errors in varve counts (e.g. deformed varves), which would have otherwise been overlooked.
Loch Lomond Stadial glaciers in Snowdonia, North Wales: glacier reconstruction and palaeoclimatic implications (B.Sc Dissertation) Supervisor: Professor Neil Glasser
With a combination of field mapping and aerial photograph interpretation the dimensions of thirty eight locally-nourished glaciers were indentified across the massifs of Snowdonia, North Wales. The palaeoglaciers were assigned a Loch Lomond Stadial (broadly eviqualent with Greenland Stadial 1) age based on morphostratigraphic principles and published dating evidence. Three-dimensional glacier reconstructions enabled estimates of stadial palaeoclimate to be made through application of a degree-day model. ​
