Teaching Interests





I was born and grew up in Edmonton, Alberta. My early interest in geography was cultivated by frequent family hiking and skiing trips to the Rocky Mountains. I was also fortunate to spend a disproportionate part of my youth in peatlands and bogs in northern Alberta working with bryologists learning about these environments. During my undergraduate program in Geography at the University of Alberta (B.Sc. (Hons) –1990), I was introduced to earth science fieldwork and took my first opportunity to carry out research in the Canadian High Arctic. That early mentorship encouraged my interest in research in the north that continues today. My graduate degrees were acquired at the Climate Laboratory at the University of Massachusetts, Amherst (M.S. – 1994) and with the northern research group at the Department of Earth and Atmospheric Sciences, University of Alberta (Ph.D. – 1998). I was awarded an NSERC Postdoctoral Fellowship that was held at Queen’s University from 1998-1999. In 1999 I accepted an academic position in the Department of Geography at Queen’s University in Kingston.

Teaching Interests

My primary teaching interests are in water resources, hydrology, hydroclimatology, geomorphology and environmental change. I am particularly keen to get students into the field to learn first hand, and many of my undergraduate courses have a field component. We collect samples, carry out snow surveys, and measure spring melt as part of a learning environment intended to link fundamental measurements, observations and theory, to conceive of and answer complex questions about the environment around us. When I can offer it, the highlight of my teaching comes from extended field courses where we really get to immerse ourselves in physical geography.

My graduate students pursue a range hydrological, geomorphic and paleohydrological research, centered on trying to develop quantitative measures of past hydroclimatic behaviour to better understand the role of landscape stability and climate forcing mechanisms. They investigate terrestrial and aquatic ecology, limnology and biogeochemical indicators as tools to decipher current system function and as proxies for understanding longer term changes. I have supervised students whose research and field work has extended across all three northern territories and Alaska, as well as British Columbia, Ontario and Québec (but we’re trying to figure out how to do this kind of work in warmer places, like the south Pacific).

My research is focused on understanding the linkages between climate, hydrology and geomorphology in permafrost and landscapes. This research is driven by the need to understand how terrestrial landscapes are sensitive to climate variability and resource development. Research work within my Environmental Variability and Extremes (EVEX) Laboratory has focused on a number of related themes: contemporary fluxes of sediment and particulate organic carbon in the streams; climatic controls over streamflow and sediment transport; the impact of rainfall on catchment processes; sedimentary processes in lakes; varved lake sediments as records of past hydroclimate and landscape disturbance; aquatic ecosystem linkages and subfossil indicators of past ecological change and long term sediment transport dynamics.

Current work is directed a number of projects in the North American Arctic, including the High Arctic, Kitikmeot region of Nunavut, and southwestern Alaska. A major emphasis has been at the Cape Bounty Arctic Watershed Observatory (CBAWO), located on south central Melville Island in Nunavut. This program, established in 2003, is directed a number of integrated landscape and hydrological initiatives in collaboration with a number of researchers (see http://geog.queensu.ca/cbawo/). My current research interests and projects reflect understanding the magnitude and relaxation of sediment fluxes from surfaces that have been disturbed at different times, the influence of snow pack on river processes, runoff generation and sediment transport characteristics, evaluation of the hydroclimatic and landscape disturbance signal in varved lake sediments, dendrochronological techniques for dating past slope failures, the chemical evolution of the lakes in the region and the application of hydrological modelling to watershed and sedimentary processes. Collaborative work currently links stream processes with the transport, characterization and origin of organic carbon in the watersheds. My work contributes to both the overall research program at Cape Bounty, and to the SEDIBUD (http://www.geomorph.org/wg/wgsb.html) and ITEX programs.

A second major project in collaboration with Darrell Kaufman at Northern Arizona University (http://jan.ucc.nau.edu/~dsk5/S_AK/index.htm) is focused on the use of varved sedimentary records to reconstruct hydroclimatic and glacial runoff during the past c. 2000 years. This work also includes monitoring of the lake sedimentary processes to develop a quantitative framework for investigating the sedimentary records.

A new initiative is to evaluate paleohydrological and sediment yield characteristics in large (>5000 km2) watersheds in the Kugaaruk region of Nunavut. This work will investigate shallow marine sediments with high sedimentation rates to scale long term hydrogeomorphic processes from c. 100-10 000 km2 watersheds.

Finally, I am a member of the Canadian PASADO team, part of a large international initiative to recover and evaluate the long sedimentary record from Laguna Potrok Aike, Argentina (http://www.ete.inrs.ca/projets/pasado/PASADO-Canada/Welcome.html). This long lacustrine sedimentary record will provide critical comparison to Antarctic ice cores during the late Quaternary.
