Current Research

My personal research program has three major emphases: (1) determination of short and long-term implications to forest health of prescribed fire and/or mechanical fuel treatments (silvicultural thinning) used in the large-scale restoration of fire-adapted forest ecosystems, (2) development of chemical, silvicultural and semiochemical-based monitoring and management tactics for Dendroctonus and Ips bark beetles, and (3) determination of the role of semiochemicals in the behavior of bark beetle species of economic importance.

Research Interests

In the future, I plan to continue developing knowledge and tools that allow managers to better care for forest resources.
