Research 

Specialized in Nematode Ecology and Nematode Biological Control. Explore environmental friendly agricultural practices to substitute Methyl bromide for soil-borne plant diseases (including plant-parasitic nematodes and fungi). Evaluating integration pest management strategies such as cover crop rotation, organic amendment, solarization, and biocontrol to manage nematode and insect pests. Utilizing nematode community indices as biological indicators to investigate the role of nematodes in soil nutrient cycling, and the impact of agricultural practices on soil ecosystem health. Study methods to enhance natural enemies of nematode. Cooperate with Agronomists to improve green manures as organic fertilizers. Current research involved:

·         Using cover crops to build an ecologically based pest management program for vegetable production. USDA (CSREES) CAR program.

·         Short-term methyl bromide alternatives for the Florida floriculture industry. USDA (CSREES), IREECGP (Integrated Research, Education, and Extension Competitive Grants Program)-Methyl Bromide Transitions Program.
