Active Projects

Research: The research that are being conducted in my laboratory include genetic improvement of lettuce and development of St. Augustine grass cultivars through conventional and molecular breeding technologies. Currently we are screening our germplasm pool for sources of resistance to bacterial leaf spot, downy mildew, corky root rot, and insects in lettuce, and chinch bugs in St. Augustine grass. The germplasm lines that show resistance to diseases/insects will be used for development of disease/insect-resistant varieties and for investigation on genetic basis of resistance.

Extension: My extension responsibility is to provide educational programming for production of lettuce and vegetative propagation of St. Augustine grass. I work closely with growers and the area vegetable crop agent to address crop production questions.
