Research

My research听integrates biogeochemistry and ecosystem ecology to study nutrient cycling in terrestrial and aquatic ecosystems. I have been fascinated by biological nitrogen fixation and symbiotic relationships between plants and diazotrophic microbes in peatlands. During my doctoral and postdoctoral work, I studied abiotic and biotic drivers of nitrogen fixation 颈苍听Sphagnum-diazotrophic associations in the context of global and climate change. My current research focuses on N2听fixation and diazotrophs community composition across the water column in the meromictic Powell Lake (BC).听Most recently, I have also been investigating potential听effects of Ocean Alkalinity Enhancement (OAE) on the marine microbiome.
