Sian Kou Giesbrecht
Pronouns: 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 carbon (C) sequestration in boreal forests under global change. My PhD research focused on how N-fixing trees, which are an important N source to terrestrial ecosystems and are commonly planted during reforestation, drive both carbon dioxide (CO2) sequestration in vegetation and significant nitrous oxide (N2O) emissions from soils. In my postdoc at the Canadian Centre for Climate Modelling and Analysis (Environment and Climate Change Canada), I worked on the representation and analysis of 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). 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
My name is Lauren and I’m a master’s student in Sian’s lab. I am originally from Newfoundland, where I completed my undergraduate degree in Biology at Memorial University. 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. |
