| Obituary in the Journal of Paleolimnology |
Tracking lake responses to recent climatic and environmental change in N Saskatchewan.
Analysis of pollen and charcoal from lake sediments in Northwestern Ontario to track the long-term Holocene climate.
A paleolimnological examination of sedimentary cladoceran assemblages and their relationship to multiple anthropogenic stressors in Algonquin Provincial Park.
Analysis of biological indicators (diatoms, chrysophytes, and chlorophyll-a) to examine the possible impacts of mink farm effluents on rural Nova Scotia lakes.
Assessing long-term data trends to understand multiple stressors on lakes that can cause algal blooms.
Reconstruction of Northeastern Ontario's Holocene climate and fire regimes using charcoal and other proxies.
Using cladoceran assemblages to assess the impacts of recent environmental stressors on several lakes within the Rideau Canal system
Using Cladocera assemblages from sediment cores to reconstruct past population dynamics of seabird populations.
An investigation on the effects of mining on nearby waterbodies in Keno City (YT) using diatoms from dated sediment cores.
A paleoecotoxicological investigation of long-term environmental changes from mining activities near Sudbury (ON).
Cladocera as community-level proxies of natural and anthropogenic chemical stress: Paleo-ecotoxicological assessments from Canadian northern lakes.
Modeling deep water dissolved oxygen changes and past hypolimnetic anoxia in south-central Ontario lakes using chironomid (Diptera) taxonomy.
I am currently researching the long-term limnological effects of forest defoliation linked to spruce budworm infestations using paleolimnological methods. Specifically, I use diatom assemblages, dissolved organic carbon and chlorophyll-a reconstructions to infer past environmental conditions.
Assessing the impact of historical and recent environmental stressors on diatom assemblages in Dessert Lake, Frontenac, ON.
Tracking anthropogenic and climate-driven changes in Ontario lakes using chironomid and chaoborid assemblages
Assessing diatom assemblage changes in minimally disturbed reference lakes (Adirondack Park, NY) for the past 200 years to understand their future trajectories.
Using chironomid and Chaoborus assemblages to reconstruct deepwater habitats in Atikameksheng Anishinabek First Nations Reserve lakes.
Assessing long-term changes in diatom and chrysophyte assemblages from lakes within the proposed boundaries of Bigwind Lake Provincial Park (Muskoka-Haliburton, ON).
Investigating how chironomid assemblages respond to multiple disturbances in Lower Rideau Lake.
The effects of recovery from acid deposition in ELA and the Adirondacks on cladocera in reference lakes.
Understanding the effects of declining sulfate deposition and climate change on Cladoceran zooplankton assemblages from a buffered reference lake in the Adirondacks, NY.
Characterising changes in zooplankton assemblages with landscape disturbance events and climate change in a historically disturbed lake in Frontenac Park
Detangling the impacts of DOC, climate, and sulphate deposition on scaled chrysophyte species assemblages in Eagle's Nest Lake over the past ~200 years.
