Research Interests

Assessing impacts of air pollution on natural environment; air pollution; soil weathering; environmental modelling.

Research Interests

My main interest are the distribution of insects in Northern Ontario, invasive species, and insect pest populations of beef and dairy farms.

Research Interests

My research interests are in environmental history, the history of science, and the roles of science in environmental policy. My current projects include a history of environmental science in the Canadian Arctic, the historical and contemporary roles of science in the salmon aquaculture industry, and the history of conservation science in relation to global protected areas.

Research Interests

  • Environmental biogeochemistry and analytical chemistry
  • Fate and transport of nutrients, metals, and metalloids
  • Development of analytical tools for emerging contaminants
  • Applications of isotope composition to paleoenvironmental studies and forensic geochemistry

Research Interests

Biogeochemistry; elemental cycling in aquatic ecosystems and their catchments; effects of regional and global-scale stressors including acid deposition, climate change, mercury and other trace metals on environmental chemistry; chemical processes in lakes

Research Interests

  • Aquatic invasive species
  • Fish population ecology
  • Fisheries management

Research Interests

Geoscience and isotope geochemistry; Researching isotopic proxies for continental weathering, numerical modeling of earth systems, planetary evolution.

Research Interests

Electromagnetic pollution, in the form of radio frequency radiation and low frequency electromagnetic fields and effects on human and environmental health. Also, therapeutic and diagnostic techniques using electromagnetic frequencies.

Research Interests

I am interested in modelling the fate and bioaccumulation of persistent organic pollutants and mercury in aquatic ecosystems and wildlife including marine mammals, and applying these models for sight-specific risk assessments.

Research Interests

My interests include climate and energy policy, particularly the planning and public engagement around low-carbon energy infrastructure. I am also interested in community sustainability and community-based research.

Research Interests

Biogeochemistry, speciation and fate of metals in the environment, with particular focus on mercury and nanoparticles. Use of stable isotopes, and measurement of fractionation and precise isotope ratios of heavy metals. Research involves field work in whole ecosystem studies and instrumental analysis using state-of-the-art high resolution mass spectrometry.

Tom Hutchinson

Professor Emeritus

Trent School of the Environment

Research Interests

Restoration and revegetation of acidic and toxic mine sites, adaptations of plants to heavy metal and acidity stress and to air pollution including sulphur dioxide, ozone and acid rain, ecology of tundra and boreal forests, use of heritage livestock breeds in sustainable agriculture.

Research Interests

  • Geo-chemistry, chemistry, and physical properties of aquatic dissolved organic matter.  These properties include elemental make-up (C, H, O, N, S), 13C, 15N, and 2H isotopic signatures, acidic properties.
  • Influence of dissolved organic matter on fate of trace metals and organic contaminants.
  • Bioavailability of DOM
  • CO2 dynamics in Boreal systems

Research Interests

I am interested in the fate and effects of contaminants in the environment, water quality, watershed management, and environmental influences on Indigenous peoples.

Research Interests

My research focuses on the application of ICP-MS in geochemical, environmental and life science fields for elemental and isotopic analysis. This includes fundamental studies of the ICP, for example isotope-dependent oxide formation during ion extraction. Areas of applied research include the development of single particle ICP-MS for the characterization of small (< 20 nm) nanoparticles in natural waters, measurement of Pb and Li isotope ratios at low (ng/L) concentrations and gas phase ion molecule reaction chemistry for chemical resolution of isobaric interferences, specifically for the measurement of radionuclides.

Research Interests

I am interested in land resources processes and assessment through Computer Modelling and Applied Geospatial Sciences, including Remote Sensing, GIS, GPS and UAV. The impacts of climate change on land, water and vegetation resources and in applications to watershed management, and agriculture.

Naomi Stock

Senior Research Scientist and Adjunct Professor

Water Quality Centre and Department of Chemistry and Environmental and Life Sciences Graduate Program

Research Interests

My primary research interests are environmental organic mass spectrometry. I am currently involved in mass spectromtery based environmental metabolomics. I am also interested in method development for analysis of organic contaminants and characterization of complex environmental samples.

Dirk Wallschläger

Professor and Director

Water Quality Centre, School of the Environment and Chemistry Department

Research Interests

Dr. Dirk Wallschläger’s research is primarily on the speciation of anion-forming trace metal(loid)s in natural environments and in industrial waste streams. He has developed analytical methods for the speciation of such elements, particularly arsenic, selenium and chromium in liquids and solids using ion chromatography coupled to inductively-coupled plasma-mass spectrometry (IC-ICP-MS). He then applies these methods to study the cycling, transformation and fate of these elements in natural and industrial systems. In the environment, the generated data are used to study geochemical transport processes and assess the risk arising from existing contaminations. In industrial waste streams, he uses these approaches to design and control custom-tailored treatment strategies.

Research Interests

My research includes assessing the impacts of pollutants, including trace metals, sulphur and nitrogen on soils, wetlands and lakes. In particular I am interested in factors that impact biogeochemical processes that impact the long-term fate of contaminants and their potential toxicity, in addition to understanding the effectiveness of remediation strategies such as liming and wood ash applications.
