About
I am an ecosystem ecologist working at the intersection of biogeochemistry, animal movement, and conservation ethics. I am currently a Presidential Postdoctoral Fellow at SEAS and was previously a Banting Postdoctoral Fellow at Memorial University of Newfoundland and Labrador.
My ecological research focuses on how animals interact with ecosystems over space and time. Specifically, I study how mammals influence biodiversity, carbon storage, and elemental cycling, and how these ecosystem changes feed back to affect the animals themselves. Using a combination of ecological theory, empirical research, and agent-based models, I link animal behavior and movement to patterns of ecosystem heterogeneity and function. In doing so, I also assess how changes to animal communities, including both species loss and reintroduction, reshape ecosystem processes. Much of my work is situated in boreal and temperate systems, where strong seasonality, migration, and environmental change tightly couple animal populations and ecosystem processes.
Alongside this ecological work, my research in conservation ethics examines how values, assumptions, and normative choices shape ecology and conservation biology and how conservation decisions affect both ecosystems and animals. In doing so, focus on identifying where ethical judgments enter scientific workflows, including problem framing, methodological choices, and management recommendations. I also develop tools to help researchers and practitioners reflect on these decisions more explicitly and navigate trade-offs among animal welfare, ecosystem function, and conservation outcomes. By making values more transparent rather than implicit, my work aims to support more rigorous, accountable, and socially grounded ecological science and conservation decision-making.
