My research program focuses on answering two basic questions:
- How do we know what we think we know about forests? (i.e., forest measurements)
- How can we utilize what we know to better understand how forests work and how to manage them more effectively? (i.e., forest modeling).
Forests are complex ecosystems that are intricately linked to environmental quality and human industry. I am interested in developing new methods for measuring attributes of forests, particularly those attributes that are typically given less attention (under-measured), such as tree bark & branch measurements. I am also interested in improving methods for accurate forest resource inventories, particularly wood products and carbon biomass inventories. This involves developing novel survey and sampling methodologies as well as new measurements. An exciting area of research I am working in now involves using models to improve sampling methods.
