Professional Experience

Research Entomologist, USDA-FS-SRS

My research focuses on the functional roles of insects in forest ecosystems and the effects of forest management on them. Recently, I have also worked on invasive insects and plants in southeastern forests.

Research Highlights

Forest Bees are More Active in the Canopy Than Near the Ground in the Southeastern U.S. (2014)
SRS-2014-192 Results from one of the first studies to investigate how bees are vertically distributed in temperate deciduous forests suggest these insects are more numerous in the canopy than near the forest floor.
Have Changing Forest Conditions Contributed to Native Pollinator Decline (2014)
SRS-2014-193 This study compared bee communities within seven common forest conditions or types on the Oconee National Forest in Georgia. Forest Service researchers found that cleared forest (former southern pine beetle spots) and mature pine stands (those that are fire-maintained) contained the highest diversity and abundance of bees due to the amount of sunlight reaching the ground and the subsequent diversity of plants. This study demonstrates that current forest management practices used to create healthy forests should be expanded because of the parallel benefits they provide to pollinator communities.
Heavy infestations of Chinese privet in forests exclude most butterflies (2011)
SRS-2011-03 Heavy infestations of Chinese privet, an invasive shrub, to crowd out most other plants in affected forests. . This results in very few butterflies using those forests. Removing privet greatly improves the forest for butterflies, increasing both the number of species as well as the total numbers.
Removing Chinese Privet Benefits Pollinators for up to Five Years. (2014)
SRS-2014-152 Results from a study by Forest Service researchers showed that removal of Chinese privet can last at least five years, during which time native plant and pollinator communities return to areas cleared of the invasive shrub..
