Sian Kou Giesbrecht (she/her)
I am a new Assistant Professor in the Department of Earth and Environmental Sciences at Dalhousie University. My research looks at nitrogen (N) cycling in terrestrial ecosystems and how it is represented in terrestrial biosphere models and Earth System Models, with a focus on N limitation of CO2 sequestration and N2O emissions in boreal forests under global change. I have worked on the representation and analysis of C and N cycling in the Canadian Land Surface Scheme Including Biogeochemical Cycles (CLASSIC), which is the land surface component of the Canadian Earth System Model (CanESM), developed by the Canadian Centre for Climate Modelling and Analysis (Environment and Climate Change Canada). I am leading CLASSIC's contributions to the Inter-sectoral Impact Model Intercomparison Project (ISIMIP) and Global Nitrogen/N2O Model Intercomparison Project (NMIP). I gave a talk at the Cary Institute of Ecosystem Studies on my research available at www.youtube.com/watch?v=YFjLMF61Kls |

Lauren Gover (she/her)
I’m a MSc student in Sian’s lab. I am originally from Newfoundland, where I completed my undergraduate degree in Biology at MUN. For my honours thesis, I researched the size structure and density of a population of northern sea cucumber in the lower Arctic. My current research interests center on how nitrogen availability will impact carbon sequestration in the boreal forest with rising temperatures, given future global warming. |

Renee Hall (she/her)
I'm a PhD student in Sian’s lab. The focus of my doctoral research is nitrogen cycling within CLASSIC-Canada, the land surface component of the Canadian Earth System Model which has been specifically tailored to the pan-Canadian domain. My research seeks to implement, examine, and evaluate the representation of nitrogen cycling and different formulations of reactive nitrogen gas emissions from wildfires in CLASSIC-Canada, and explore how these reactive nitrogen gas emissions and their feedbacks to climate change will evolve over the 21st century. Prior joining Sian’s lab I worked as a data scientist, and my previous projects include fungal spore prediction for agricultural pathogens and the design of forestry modelling for optimizing carbon sequestration and minimizing environmental risk factors. My undergraduate degree with Quest University was in Agricultural Sustainability, where my honours thesis analyzed life-cycle assessment studies on the greenhouse gas emissions from beef production systems. |

Paige MacCarthy (she/her)
I'm an undergraduate honours student in Sian’s lab. I am currently in my fourth year majoring in environmental science at Dalhousie University. I grew up in Barrie, Ontario. The focus of my honours thesis research is to explore the comparison between the effects of nitrogen deposition and carbon dioxide fertilization on terrestrial global carbon and nitrogen cycling processes. |

Allie Pell (she/her)
I’m an undergraduate honours student in Sian’s lab. I am in my fourth year of a Bachelor of Environmental Science degree. My undergraduate thesis research looks at the carbon and nitrogen content of above-ground biomass in Canadian forests compared to the nutrient composition of associated soils |
