My research focuses on conservation biology issues. I investigate how ecological processes and environmental factors affect species persistence, species dispersal and species range dynamics. My research is at the interface of several disciplines (spatial ecology, conservation, forest ecology, disturbance ecology, community ecology, landscape genetics, spatial epidemiology, spatial statistics, spatially-explicit modeling, and network theory) where the most important challenging problems lie.
My current research includes using a variety of tools, approaches and model taxa to answer today’s most pressing ecological and conservation problems. I am particularly interested in understanding the mechanisms underlying changes in distribution and abundance, the role of abiotic and biotic factors on individuals and populations, and the likely future change in structure and function of communities and ecosystems. I currently hold a Canada Research Chair (CRC) in Integrative Wildlife Conservation.
My current research focuses on the application of molecular genetics and genomics to answer basic research questions in forensic science and conservation genetics, particularly relating to non-human DNA profiling, natural resource management and conservation. The establishment of DNA markers, databases and analyses for non-human species forms the core of my research program and services the evidentiary needs of forensic cases and provides data to address biological, conservation and management questions. I currently hold a Canada Research Chair (CRC) in DNA Profiling, Forensics and Functional Genomics.
My current research focuses on physical and satellite geodesy, merging multi-platform geodetic data, remote sensing in geo-engineering applications, positioning/navigation, height systems and surveying. While my research group delves into various applications in engineering and the geosciences, the common underlying theme is improving our understanding of uncertainty embedded within various geodetic datasets. The ultimate goal is to establish means for fusing, modeling and visualizing datasets by employing quality indicators. Examples of this include projects on ‘numerical tools for interpreting rock surface roughness’, ‘estimating uncertainties and fusion of multi-platform geodetic data’, ‘augmenting comprehension of geological relationships by integrating 3D laser scanned hand samples within a GIS environment’, ‘assessing the feasibility of using satellite gravity observations for detecting large scale landslides’ and ‘detecting surface water using airborne LiDAR and TerraSAR-X data’.
As a researcher at the Ontario Ministry of Natural Resources and Forests (OMNRF), my research focuses on understanding how behavioural ecology of individuals translates into spatial and temporal population dynamics. I am interested in landscape ecology and landscape connectivity, and also in understanding the potential impacts of climate change on wildlife communities. I have been involved in research projects on many species and ecosystems, including work on fishers, martens, bobcats, lynx, wolverines, mink, muskrats, wild turkeys, and flying squirrels.
My current research includes analysis of recent forest disturbance and recovery patterns using satellite image time-series, and aerial remote sensing for geomorphological, hydrological, ecosystem structure and biophysical assessment. My research in environmental remote sensing is funded by NSERC Discovery and CRD grants and research contracts with the Canadian Forest Service. My contributions have been recognized by the Alberta Emerald Foundation (Excellence in Research and Innovation Award, 2005), the Canadian Remote Sensing Society (Gold Medal, 2007), and the University of Waterloo Faculty of Environment (Distinguished Alumni Award, 2011). I have previously held academic and administrative positions at Memorial University, University of Calgary, and University of Saskatchewan.
My research focuses on using computer models to improve our understanding of pollutants in the environment. This initially involves analyzing soil, water and air samples in the lab and using the data to create equations and formulas as the basis for computer models. Modelling what pollutants are doing now will allow us to predict what they will do in the future, which will allow for better decision-making today to enhance the quality of our natural environment and well-being tomorrow. I currently hold a Canada Research Chair (CRC) in Environmental Modelling.
The primary focus of my recent research has been the combination of microanalysis of metal-bearing minerals in mine waste, contaminated soils, sediments and dust with speciation analysis of co-existing waters to understand mineral-water interaction. By combining, near-simultaneously, three types of synchrotron experiments using a microfocused beam (eg. microdiffraction or microXRD), my lab has been able to unambiguously identify secondary minerals at the microscopic scale. Recently, we have applied automated mineralogy based on scanning electron microscopy to determine how metals are distributed amongst solid phases in contaminated materials. For the most part, I have focused on pH-neutral mine waste environments such as gold mines where associated arsenic (As) and antimony are of concern and mobile at neutral pH. Most of my fieldwork is in the Canadian North, but other sites include Peru, Chile, Slovakia, Newfoundland and Nova Scotia.
My current research focuses on understanding how human landscape alteration affects biodiversity patterns and processes. I’m specifically involved in three broad areas which are complementary to each other: spatial ecology (assessing spatial and temporal patterns to identify key processes shaping population and community dynamics), metacommunity dynamics (assessing the degree and determinants of connectivity among ecological communities in the context of landscape pattern and change), and landscape genetics (providing a mechanistic link between landscape structural connectivity and functional connectivity).
My current research interests include environmental health risk assessment, management and communication; Indigenous environmental health with focus on Arctic populations; Indigenous knowledge and science for environment and health research; and mixed methods research.
My current research interests include metal speciation and bioavailability in freshwater, the impact of mining exploration on biogeochemical cycles of metals in freshwater, and development of new methods for characterizing dissolved organic carbon (DOC) and DOC-Metal interactions. I am currently a member of the Trent Water Quality Centre and hold a Canada Research Chair (CRC) in Aquatic Sciences & Biogeochemistry.
Since completing my MSc (Forestry) at UBC in 1997, I have worked in university, provincial government, environmental consulting, and conservation authority settings which gives me the unique perspective of knowing what types of skills employers need. My role is to help graduate student trainees in the CREATE Enviro program gain professional skills through workshops and professional placements to better prepare them for the environmental workforce upon graduation.
I completed my MSc (Wildlife Ecology) at the University of Wisconsin in 1996 and my Doctor of Veterinary Medicine degree from Washington State University in 1999. Since then, I have practiced as a veterinarian and then moved on to become a sessional instructor at Trent University in face-to-face and online science courses in 2007. I have also developed three online undergraduate courses through Trent Online in cell biology, anatomy and physiology. My current role is to coordinate the development of online graduate level courses by researchers in the CREATE Enviro program for a newly proposed online professional Master of Environmental Monitoring and Assessment program slated to begin in September 2018. These courses will also be taken by CREATE Enviro trainees.
