Population / Community Ecology
Integrated pest management of woody ornamental pests; biology, ecology, and taxonomy of Ephemeroptera; aquatic macroinvertebrates as indicators of water quality
Woody ornamental pest management program; integrated pest management of ornamental pests; diagnosis of arthropod pests of trees and shrubs
My duties include insect and mite identification and management suggestions for pests of woody ornamental plants, Christmas trees, forests, and turfgrass as well as aquatics. I write entomological fact sheets (Entomological Notes) on arthropod pests of woody ornamental plants, Christmas trees, and forests.

I'm currently developing an integrated pest management system for woody ornamental pests in Pennsylvania, and on the establishment of aesthetic and economic thresholds for arthropod pests of woody ornamentals. I've presented over 700 extension programs, invited guest lectures, and workshops in Pennsylvania and surrounding eastern states. I serve as a member of the University Tree Commission at the University Park campus. I'm developing a native elm bark beetle and smaller European elm bark beetle integrated pest management program for use in maintaining healthy stands of American elm in urban landscapes. I provide diagnostic information for the management of arthropod pests of ornamental plants, Christmas trees, forests, turfgrass, greenhouse bedding plants, and fruit and nut trees and on the identity of aquatic macroinvertebrates.
