I have been working to understand the consequences of environmental change, driven by the changing climate, on Arctic tundra ecosystems through long-term observations and field experiments. Studies of plant growth, phenology and reproduction, biodiversity responses, biotic interactions, evolutionary and migration potential of plant species, carbon and nutrient fluxes, and effects of permafrost disturbance form the basis of investigations by my group. We also work in Arctic communities to help northern students understand and interpret observations of environmental change by elders through shared field and class experiences and participation in science-based projects on berry producing shrub species.
My main area of interest is Geographic Data Visualization, and I teach courses in Cartography, Geographic Information Science and Remote Sensing. I work on collaborative research projects that use GIS to visualize environmental history and I undertake research on the evolution of the teaching of cartography in academia, and the scholarship of teaching and learning.
I work at the intersection of climate science, glaciology, geomorphology and oceanography. My research focuses on ice-climate and ice-ocean interactions, the formation of glaciated landscapes and landscape response to climate change, from the temperate regions of BC and Patagonia to the polar regions of Greenland and Antarctica. My team and I integrate field observations, spatial analysis, numerical modeling and theory to quantify the impacts of climate change on glaciers and landscapes.
I study the interplay between market processes and public policy in the production of urban social inequality. Current research projects focus on the racialized dynamics of capital investment and disinvestment in U.S. cities, evolving trajectories of gentrification, histories of epistemology in urban geography, and the urban implications of mass social networking practices.
I work, in the style of institutional political economy, on a range of issues relating to economic geography, urban restructuring, and state transformation. Much of my research is concerned with the ways in which ostensibly global processesfor example, forms of market-oriented governance (a.k.a. neoliberalization)are (re)remade through local sites and grounded practices.
My research interests bring together political geography, political ecology, and war studies. I have focused most of my work on the links between natural resources and armed conflicts, but also examined the political economy of war and reconstruction, the resource curse, corruption, as well as natural disasters and political crises.
I have two current projects in urban social geography. The first is a comparative study of housing market bubbles, their causes, social consequences, and policy responses in five global cities. A second project involves participation in the national Neighbourhood Change Research Partnership that is examining growing income inequality and polarization in large Canadian cities.
My general interest in air pollution meteorology is increasingly focussed on broad issues of climatic and environmental change associated with the long range transport of pollutants, mineral dust and forest fire plumes. Transport of such pollutants have the potential to significantly influence local air quality.
My research focuses on transnational migration, labour precarity and performance. I am preoccupied with how to put stories of transnational migration and family separation into circulation, with the politics of testimony and witnessing, and the obligations of witnessing and dialogue within, beyond and across national and community borders. I am developing new research on the outsourcing of eldercare.
My research focuses on the influence of climate variability and change, in conjunction with forest and glacier dynamics, on hydrological processes and the patterns of streamflow and water quality. I work closely with practitioners, government agencies and utilities to integrate the best available science into environmental monitoring, management and policy.
