Research Experience/Appointment

1991 - 2012, Assistant, Associate and Full Professor, School of Plant, Environmental and Soil Sciences, (Department of Horticulture), Louisiana State University Agricultural Center. Vegetable crops physiology and cultural practices research. Projects included investigation of differential fruit abscission in pepper genotypes, sustainable production practices, fertilization and plant population studies of processed peppers, watermelon plant establishment, postharvest quality evaluation of watermelon and mixed melon, organic fertilizers, cover crops, and colored plastic mulches and row covers for vegetable production, and the effect of hands-on science education on environmental awareness and science achievement of public elementary school students.

1987 - 1990, Graduate Research Assistant, Dept. of Horticultural Science, North Carolina State University. Dissertation research: the tolerance of sweet potato genotypes to various postemergence herbicides was evaluated in field and greenhouse studies. The basis of differential tolerance of sweet potato to asymmetrical triazines was investigated in phytotron and laboratory studies.

1985 - 1987, Graduate Research Assistant, Dept. of Horticultural Science, North Carolina State University. Thesis research: various row cover materials were evaluated for the promotion of early and total yield of trickle-irrigated muskmelons. Several herbicides were investigated for use with different row covers and plastic mulch in muskmelon production.
