Career Summary:

My research focuses on the impact of silvicultural practices on understory plant communities. Some specific examples include: the effects of herbicide application on recovery of vegetation following treatment, long-term understory vegetation change in an old growth remnant forest, competition among woody species during the stem exclusion stage of stand development, and silvicultural practices to enhance species composition of regeneration. I began my career with the US Forest Service in 1991 as a Biological Sciences Technician.
