Background: My background is in physical geography and geomatics. After earning a BSc at Trent Univeristy in physical geography and biology, I completed the post-graduate GIS (Application Specialist) program at Sir Sandford Fleming. I worked for five years as a GIS Specialist and Land Survey Manager for a geophysical exploration firm that focused on projects in remote US and Canadian locations. My research interests in northern water resources manifested during my graduate program at Wilfrid Laurier University, when my fieldwork was concentrated in Old Crow Flats, Yukon.
Research program summary: Lakes and wetlands, which are abundant across northern landscapes, sustain ecological and cultural integrity and represent important components of hydrological and biogeochemical cycles. There is widespread evidence that these landscapes are experiencing differential responses to shifts climate and land cover. To enhance our understanding of how these systems are changing, my research program integrates several approaches to identify drivers of hydroecological conditions over multiple spatial and temporal scales. Water chemistry and isotopic tracers from water sampling campaigns are used to evaluate differences in water balance and runoff generation processes among catchments. Remote sensing approaches are utilized to identify temporal patterns in catchment land cover characteristics, which are integrated with ground-based assessments of hydrology, active layer and tree ring data. Historical context of landscape changes is complemented using paleolimnolgical analyses of lake sediment cores. Capturing evidence of past and present interactions among hydrological features, land cover and climate provide the basis to anticipate how important northern wetlands may respond in the future. Findings generated from this research program will serve to inform land management and adaptation strategies as these important landscapes continue to change.
