Teaching Interests





I was born in Pelham, in the Niagara Region of southern Ontario. My undergraduate training in Biology and Geography was obtained at Brock University (B.Sc. (Hons) –1983, BEd – 1986) and my graduate degrees were acquired at the University of Waterloo (M.A. – 1986, PhD – 1997). From 1989-1995, I was a research scientist in the Earth Observations Laboratory at the University of Waterloo. In 1995 I accepted an academic appointment in the Department of Geography and Faculty of Environmental Studies at York University in Toronto. I moved to Kingston with my wife and two children in 1999 to accept a faculty position with the Department of Geography at Queen’s University. While at Queen’s, I have served the Department as Graduate Chair (2002-2006), Acting Head (2007-2008), Associate Head (2008-2009) and Head of Department (2010-present).

Teaching Interests

As part of my graduate training, I was a teaching assistant for courses in physical geography and remote sensing. Through this experience, I found that I really enjoyed teaching and working with undergraduate students. This led to my pursuit of a B.Ed. degree. I spent a year (1986-87) in Fenelon Falls, Ontario, teaching high school geography and then two years (1987-89) at the School of Natural Resources, Sir Sandford Fleming College, Lindsay, Ontario teaching remote sensing and photogrammetry. However, the desire to pursue research activities and bring those experiences to the classroom eventually directed me back to school to pursue my PhD. Since arriving at Queen’s, I have developed a suite of remote sensing and digital image processing courses at the undergraduate and graduate levels. My graduate students pursue a range of remote sensing related research interests. These research activities tend to revolve around the application of high spatial and spectral (i.e., hyperspectral, LiDAR) remote sensing data to characterize boreal forest and arctic ecosystems. I have supervised graduate students whose research and field work has extended from the Canadian High Arctic to the equator (Indonesia).


My research focus, and that of my students is on the application of remote sensing data for estimating biophysical variables (e.g., percent cover, aboveground biomass, leaf area index (LAI), fPAR) of arctic and boreal ecosystems. These biophysical variables are linked to many ecosystem processes. For example, biomass information plays a significant role in assessing carbon stocks; is an important element in global change and productivity models; and is a measure of vegetation community structure which influences biodiversity. Current research projects include the examination of tolerant hardwood and boreal forests using LiDAR data to characterize forest stand structure and estimate biophysical/physiological variables. In addition, we are examining satellite remote sensing data and spectral derivatives to classify arctic vegetation communities and estimate biophysical/ecosystem variables with the purpose of linking these to carbon dioxide exchange at study sites on Boothia Peninsula, Melville Island, and Baffin Island, Nunavut. Further, we are also examining the utility of RADARSAT synthetic aperture radar (SAR) data to model soil moisture and permafrost degradation across Arctic watersheds. Central to these studies, and our research, is the influence of spatial resolution on the estimation of these ecosystem/biophysical variables at local and regional scales.

Research Projects:

Principal Investigator

  • Remote Sensing of Environmental Change across Northern Terrestrial Ecosystems (NSERC Discovery Grant)
