Current Research

I investigate forest structural and compositional change (i.e., stand dynamics) to inform management. Active forest management plays an integral role in providing society the resources required to function and flourish. Overall, my research elucidates stand responses to natural disturbances or silvicultural practices in multiple benefit forests, and therefore has implications for timber production, biodiversity, restoration, and resilience to future disturbances.

Research Interests

• Silviculture
• Stand dynamics
• Disturbance ecology
• Emulating natural disturbances
• Natural regeneration
• Fire and fuels

Why This Research is Important

Understanding how forests change in response to management decisions and natural disturbances is imperative for delivering sustainable benefits to forest land owners. By evaluating forest structural and compositional change in the past we are able to assess the tradeoffs associated with management activity or inactivity. Ultimately, this leads to enhanced understanding of forest dynamics and improved decision making for the future.
