I am a microbial ecologist with a diverse academic and professional background. In England, I studied community and population ecology before moving to Canada to research the biogeochemistry of wetland soils. I combined my knowledge of the living and physical environment in my doctoral and postdoctoral studies to investigate the impact of climate change on forest and wetland microbial processes. Prior to joining UNBC, I spent five years as an environmental consultant working on projects across Canada. This experience has prepared me to train undergraduate and graduate students for a successful career in industry.
Research and Expertise
I have broad interests in microbial ecology and study a variety of aquatic and terrestrial ecosystems, such as forests, peatlands and lakes. I also have interests in applied settings such as managed forests and environmental remediation of industrially degraded sites. Currently, my focus is on the microbial response to human-induced environmental change that has consequences for biogeochemical (nutrient) cycles important for ecosystem health. Specifically, I'm examining the microbial control on soil organic carbon accumulation and decomposition to greenhouse gases. Understanding soil organic carbon dynamics under a changing environment is important as there is potential to exacerbate global warming. But through management soil organic carbon storage could be a viable strategy for climate change mitigation.
Students are an essential component of my research program. Please contact me via email if you are interested in finding out more about graduate and undergraduate research opportunities.Research Fields:
