My research focuses on the development and application of novel geochemical proxies to place constraints on the rates and magnitude of ice melt in glacial and permafrost environments, and associated environmental feedbacks. I use elemental, stable isotopic, and radiogenic isotopic analyses of meltwater in cryosphere systems to quantify climate induced hydrologic evolution within these systems. Specifically, I investigate: the evolution of melt source contribution in glacial and permafrost environments over time; the storage length and subsequent hydrochemistry of subglacial meltwater; the impact of meltwater fluxes on marine chemistry in the present and over glacial-interglacial timescales; shifting nutrient availability and vegetation in Arctic environments with increased permafrost degradation; and feedbacks between cryosphere systems and the sequestration and release of greenhouse gases with a changing climate.
