Research Entomologist
Education:
B.S. Environmental Biology/Zoology, Michigan State University
M.S. Entomology, The University of Georgia
Ph.D. Entomology, Purdue University
Research Interests:
The biology, ecology, and behavior of insect pests and vectors of potato plant pathogens. The epidemiology and mechanisms of insect-vectored potato plant pathogens.
Aims:
To improve our knowledge of insect vector–pathogen–host plant interactions as well as mechanisms of pathogen transmission. To apply that knowledge toward the development of sustainable management solutions.
Background:
Potatoes are the dominant vegetable crop produced in the United States, the bulk of which are grown in the Pacific Northwest. Insect damage and disease symptoms in potato tubers are not suitable for fresh markets or processing, necessitating effective management tools. For insect-vectored potato pathogens, this often requires managing the vectors and breaking the pathogen transmission cycle. However, current potato pest management strategies are heavily reliant on pesticides which can be financially and environmentally costly and may not be effective at preventing or mitigating insect-vectored pathogen outbreaks.
Approach:
Research contributing to our knowledge of potato pest biology, ecology, and behavior, as well as insect-vectored potato pathogen reservoirs, vectors, transmission mechanisms, and epidemiology. Ideally, this knowledge can then be incorporated into an integrated pest management approach to developing effective tools for outbreak prevention and mitigation.
