David Olefeldt - PI

David is the Campus Alberta Innovates Program (CAIP) research chair in Wetland Restoration and Catchment Management at the Department of Renewable Resources at University of Alberta. Research interests include peatland biogeochemistry and catchment science, with a focus on peatland regions within the boreal and subarctic. Read abbreviated CV here.

Cristian's broad research interests are carbon cycling in permafrost regions and feedbacks to climate change, biogeochemistry of peatlands and belowground soil redox dynamics linked to hydrology. Cristian is an active member of the Permafrost Carbon Network, leading a synthesis effort on the use of 14C within the permafrost region.





 

Liam Heffernan - PhD student

Liam's project focuses on the long term implications of permafrost thaw for peatland carbon storage and greenhouse gas balance. His project combines several research approaches, including peat stratigraphy and dating, soil flux measurements, and below-ground profiles of dissolved and gaseous carbon.  

 

 

 

 

 

 

Katheryn Burd - MSc student

Katie's project investigates the implications of fire and permafrost thaw in peatlands for the export and biodegradability of dissolved organic carbon (DOC). She is monitoring water quality at both burned and unburned catchments in southern Northwest Territories with state-of-the-art instrumentation for detecting rapid shifts in DOC concentrations and composition. 

 

 

 

 

 

 

Carolyn Gibson - MSc student

Carolyn's MSc thesis focuses on understanding the role of fire on permafrost stability and carbon cycling on peat plateaus in the discontinuous permafrost zone. Her thesis combines remote sensing approaches and field data. She is co-supervised by Mike Flannigan.

 

 

 

 

 

 

McKenzie Kuhn - MSc student

Kenzie's thesis focuses on understanding the consequences of thermokarst lake expansions on the Taiga Plains in western Canada with regards to greenhouse gas emissions. She will contrast biogeochemistry in peatlands lakes with variable groundwater connectivity, and carry out lab incubations to understand potential for greenhouse gas production. 

 

 

 

 

 

 

Alexander Mertens - MSc student

Alex's project is aimed at understanding controls on lake water chemistry in low relief glaciated regions of Canada. He will be using data from thousands of of synoptically collected lake and pond water samples along with landscape characteristics to create an overall generalized conceptual model that can be adapted to the range of lake physiographic settings across the Western Boreal Forest.
