Vita

Area of expertise:

Biological control; Entomopathogenic nematodes and symbiotic bacteria; host plant resistance; molluscicidal nematodes; foliar nematodes; IPM

Soil ecology; quantifcation and maximization of ecosystem services of the soil food webs in urban and agroecosystems; soil nematode communities as bioindicators of soil health

Urban ecology; quantifying and maximizing ecosytem services and human well-being in cities; ecological landscape planning and management; urban agriculture, stormwater management

Ph.D. 1990 University of London

My research interests range from molecule to ecosystem, disciplinary to interdisciplinary, and basic to applied with current emphasis on biological control, soil ecology and urban ecology. Specific projects include

Quantification and maximization of ecosystem services particularly supporting (soil biodiversity and nutrient cycling), regulating (surface and belowground biocontrol; air quality, and water quality), and provisioning (food, water, and energy) services in urban and organic farming systems
Developing new strategies to utilize entomopathogenic nematodes in vegetables, fruits, nurseries, and landscapes;
Biology and management of foliar nematodes on hosta and other ornamentals
Molecular mechanisms of virulence and symbiosis of entomopathogenic nematodes and bacteria
Molecular, genetic, and physiological approaches to extend longevity and stress tolerance in entomopathogenic nematodes; and
Molecular and physiological mechanisms and management of induced plant resistance
