Biography
Roseanna's research focuses on understanding climate, nutrient, and human driven lake ecosystem change over timescales of 100s to 1000s of years. I am particularly interested in arctic and subarctic lake ecosystems, which are highly sensitive to a warming climate and currently undergoing large scale change.
Teaching Summary
Roseanna teaches lake systems, water quality, climate change, and statistical analysis.
Roseanna is co-convenor for:
- Academic Skills (BIOS 1069)
Roseanna currently teaches on the following courses:
- Climate Change Science (BIOS2013)
- Environmental Geochemistry (BIOS2044)
- Climate Change Mitigation (BIOS3103)
Research Summary
Research interests include:
- freshwater invertebrates (such as Chironomidae, non-biting midges) as a proxy for past climate and lake ecosystem conditions
- changes in lake methane production with changing climatic and environmental conditions
- development and application of statistical tools to increase our understanding of complex systems, such as ecosystems
- human-driven lake ecosystem change
