My research focuses on reconstructing changes in the cryosphere through an integrated approach that combines geomorphology, geochronology, sedimentology, remote sensing, and numerical modelling.
Using a combination of 10Be cosmogenic nuclide surface-exposure dating and numerical modeling, I seek to constrain the timing of rapid ice-sheet thinning and disintegration across the interior of British Columbia. This work will help refine our understanding of the style of deglaciation of the Cordilleran Ice Sheet and explore the climate forcings behind rapid changes in ice configuration and sea-level rise during the last deglaciation.
I use 10Be exposure ages from elevation transects (“dipsticks”), together with ice-sheet modeling, to constrain the magnitude and timing of ice thinning and deglaciation across Patagonia. This approach informs ice-unloading histories in tectonically active settings and helps explore the climate forcings that drive mid-latitude ice-sheets collapse on millennial-to-centennial timescales.

Using cosmogenic nuclide surface-exposure dating of moraine boulders, geochemical proxies from lake-sediment cores, seismic imaging of submerged glacial landforms, and geospatial analysis, I constrain the spatially variable nature of Holocene glaciation in the Andes, particularly in Patagonia, to reconstruct cryospheric conditions prior to the industrial era. Additionally, through numerical simulations, I quantify ice-volume changes over the last few centuries and validate these estimates using geological evidence.
I study the evolution of the Patagonian Ice Sheet over glacial and interglacial timescales by mapping and dating glacial deposits across Patagonia. Using a combination of cosmogenic nuclide surface-exposure dating and luminescence dating, I seek to constrain the timing and structure of glacial maxima of mid-latitude ice sheets and their relationship to Southern Hemisphere climate.
I seek to understand the impact of ice unloading on the solid Earth by reconstructing relative sea-level change around the northern Antarctic Peninsula, particularly in the South Shetland Islands. Using a combination of radiocarbon dating, drone imagery, and topographic surveys, I constrain the timing of ice fluctuations and associated relative sea-level change.

My goal is to provide geochronological constraints on the timing of ice-sheet and glacier advance and retreat around the Antarctic Peninsula, particularly on James Ross Island. I follow a morphostratigraphic approach that combines detailed mapping of glacial landforms and analysis of glacial stratigraphy with radiocarbon and luminescence dating.
