My research is currently focused on the biogeochemical cycling of nutrients and related elements, and human and climate related disruptions of these cycles. For more than a decade, I have conducted whole-ecosystem research at the world-renowned Experimental Lakes Area studying reservoir creation, ecosystem metabolism and eutrophication. To study the fate of biogeochemical elements, I often use stable isotope measurements with process-based ecological models. I am a co-founder of the Coalition to Save ELA.

Daniela is a part of the FORMBLOOM project, where she will help assess harmful algal bloom formation in Jackfish Lake, NWT.
Mackenzie Schultz, MSc student
Mackenzie completed her undergraduate degree at Wilfrid Laurier University studying Biology and Geography. She is excited to return for her MSc, as part of SAMMS, where she will help characterize both terrestrial and aquatic metal deposition histories, stores, and pathways as a result of the mining industry.
Jeremy Leathers, MSc student
Jeremy completed his Bachelor of Science degree in biology and geography at the University of Winnipeg. He is looking forward to starting an MSc as a part of SAMMS, where he will help to determine the total organic carbon and arsenic stored within soil and peat within catchments affected by mining activities in the Northwest Territories.
Catherine Goltz, MSc student
Catherine completed her BSc (Honours) at the University of Winnipeg looking at how nitrogen influences cyanobacterial blooms and toxins. Her interest in blooms continues in her MSc where she will look at how iron release from sediment can be suppressed to shift algal communities in lakes.
Matthew Roberts, MSc student
Matthew completed his BSc in Biology and Chemistry at Wilfrid Laurier University. He returned to Laurier for his MSc, looking at shallow lake stratification and its impacts on phytoplankton communities.
Alexia Marten, BSc student
Alexia is an undergraduate student at Laurier who is in her final year studying Environmental Science. Her thesis is focusing on determining spatial distribution patterns of phosphorous deposition through out Muskoka, she is working with other students through out eastern North America through the Linked Undergraduate experiments on Nutrients network (LUGNuts).
Megan L. Larsen, Postdoctoral fellow
Megan Larsen is a microbial evolutionary ecologist who has focused on eco-evolutionary feedbacks in microbial communities induced by nutrient stoichiometry. She investigated predictive models for cyanobacterial bloom formation as part of the cross-institutional FORMBLOOM) project. Currently, she works with environmental genomics data.

Pieter Aukes, Postdoctoral fellow
Pieter looked at the variability in natural dissolved organic matter (DOM), with the objective of distinguishing indicators of labile DOM. Liquid Chromatography-Organic Carbon Detection (LC-OCD) uses a size-exclusion method to provide a highly detailed analysis of DOM composition. His research classified a variety of arctic and sub-arctic surface and ground water environments, with the aim to observe differences in composition between environments, as well as to identify components which may indicate the overall lability of DOM in the SAMMS and Northern Water Futures projects. He is now a water sciences instructor at the Southern Alberta Institute of Technology (SAIT) where he’s teaching field techniques and data visualization.
You can find more information on Aukes’ projects on his personal website.
Jared Wolfe, Research associate
Jared completed his MSc at the University of Regina studying the impacts of Oil Sands industrial development on historical algal communities in northern Saskatchewan. He is currently investigating harmful algal bloom formation and decline in the Experimental Lakes Area as part of the FORMBLOOM project. His interests are in studying relationships between ecosystem components, particularly the relationship between humans and the environment.

Rachel Henderson, MSc student
In September 2020, Rachel defended her MSc thesis on the variability of dissolved and particulate stable carbon isotope values in a eutrophic boreal lake at the Experimental Lakes Area. She is interested in the applications of geochemistry to solving environmental problems and how science can better inform public policy.

Friends are our collaborators at a variety of organizations and institutions. In some cases they are co-supervisors, committee members, and/or co-applicants on grants. Often they are co-authors on our papers. In all cases, they are the extended group of people I like to work with. The model of a single professor with a lab full of students is antiquated and simply not how environmental and biogeochemical research is done.
