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
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.
