I am currently the assistant project leader on the Sierra Nevada Adaptive Management Project (SNAMP), which studies how fuel reduction treatments affect spotted owl occupancy status and reproductive rates. For more information, see the owl research page.
Previously, I helped facilitate the canopy reduction experimental study on the Eldorado and Tahoe National Forests in the Sierra Nevada. We used radio telemetry methods to record the nighttime foraging locations of the owls. We were interested in the response of the owls to timber harvests, using the pre and post harvest location data.
In general, my research interests include forest species habitat conservation and habitat management.

- BS, Biology. University of Nebraska, Lincoln 1996.
I enjoy birding, hiking, backpacking, snowboarding, and photography.
