Research Specialization

My research focuses on applied population biology, particularly as it relates to the invasion and management of arthropod pests and vector-borne plant pathogens. Typically, this includes greenhouse experiments, field experiments, or large-scale monitoring programs coupled with population dynamics or statistical modeling. Recent topics include: Landscape ecology of arthropod invasions in vineyards, species distribution modeling for a vineyard pest complex, urban spillover of an invasive vector into commercial citrus, mitigating the role of nursery stock in invader spread, climatic effects on plant disease, epidemiological significance of vector behavior, and associational effects among plants mediated by an invasive herbivore.

Extension Activities

As a cooperative extension specialist, I regularly give presentations, write articles, develop online resources, or otherwise consult on issues related to arthropod invasions and vector-borne plant disease. Frequent topics include: Sharpshooter and Pierce’s disease biology and management, Asian citrus psyllid and huanglongbing biology and management, invasive pests in vineyards, arthropod pests in the garden or urban landscape, and development of pest or disease monitoring programs for grower groups and regulatory agencies.
