I am currently a postdoctoral researcher at McGill University. I received a PhD at McGill University in Dr. Tim Moore's lab in the Dept. of Geography. My research integrates biogeochemistry and ecosystem ecology to study nutrient cycling in northern peatlands.
My current research primarily focuses on: 1. ecological drivers controlling N2 fixation with the special focus on environmental and biogeochemical controls in the context of global and climate change. More specifically, I am interested in the coupling of N and P-cycle, and the impact of N:P stoichiometry in nutrient-limited bogs on N2 fixation. 2. feedback loops regulating N2 fixation in peatlands that arise due to the anthropogenic influences (particularly increased N deposition). 3. plan-microbe interactions and the role of microbiome in Sphagnum growth acclimatization to climate warming |
Other interests:
- drivers of net primary production of bryophytes in nutrient-poor environments
- ecosystem stoichiometry and the use of stable isotopes to infer ecosystem functioning
- the role of methane-oxidizing bacteria as an important diazotrophic community in peatlands
- climate and human-induced changes to the ecosystems
