Research on climate change
Current research and/or projects
I have always enjoyed being in the outdoors and exploring nature, so a career in ecology came naturally to me. From the grandeur of the Pacific Northwest rainforest to the stark beauty of the arctic tundra, I’ve been fortunate to work in many different ecosystems during my B.Sc. and Ph.D. training and now as a research scientist, studying vegetation dynamics, soil properties, and connections between soils and streams. I currently work to understand the role that climate plays in forest functioning, and am also interested in how science concepts are used in conservation management.
Research and/or project statements
Current Research Projects:
- Co-leadership of the Newfoundland and Labrador Boreal Ecosystem Latitudinal Transect (NL-BELT).
- The role of climate on soil carbon and nutrient stocks, transformations, and export in mesic Eastern boreal forests.
- Climate and seasonal controls on dissolved organic carbon transport in soils.Carbon accounting at the watershed scale: understanding the connection between terrestrial and aquatic landscape features.
- The role of climate on forest productivity in Eastern boreal forests.
- The concept of landscape intactness as used in applied science and forest management.
