- Provide research leadership for environmentally responsible solutions to insects impacting plants in urban and suburban landscapes including lawns, golf courses, sport fields, street and shade trees, parks, pastures, nurseries, and other settings
- Enhance basic understanding of pests and beneficial insects, their interactions with plants in urban landscapes, and their responses to anthropogenic disturbances , especially pesticide inputs
- Conduct hypothesis-driven innovative work in conservation biological control, eco-toxicology, urban biodiversity conservation, host plant resistance, and tri-trophic interactions using turf and landscape study systems
- Develop future leaders in Urban Landscape Entomology through commitment to graduate education
We interact with professional landscape and turf managers, industry and government scientists, and the public. Grad students gain independent research skills as well as extensive teaching, extension, and outreach experience, opening diverse career opportunities. Nearly all of our graduates have gone on to rewarding scientific careers in academia, state or federal positions, or in industry.
We have inordinate fondness for soil insects, especially scarab grubs, as well as Japanese beetles, caterpillars, wood borers, scale insects, leaf miners, ants, earthworms, and other invertebrates important to urban ecosystems. Another focus is on conservation of beneficial insects, including pollinators, and their ecosystem services. New systems are readily taken on in response to students' interests and emerging pest problems.
On my web site you will find a brief personal biography, examples of past and present research projects, a list of selected recent publications from our lab, information about current and past graduate students, and brief descriptions of courses that I teach.
Some Accomplishments of Students from Our Lab:
- 40 past and present graduate students
- Three recipients of John H. Comstock Award, ESA’s most prestigious graduate student recognition
- Seven recipients of UK College of Agriculture Outstanding Grad Student Award
- ESA Leadership Award in Applied Entomology, ESA President’s Prize, ESA scholarships, GCSAA Watson Fellowship, prestigious University fellowships, 18 winners in OVEA Student Paper Competition
- Former students include 9 University faculty members; leaders in Industry, USDA, State Extension and Regulatory positions, and lawn and landscape consultants and/or business owners.
- >70% of the nearly 200 refereed scientific papers originating from our lab had student(s) as the primary (first) author.
