Research Interests

My main research focus is microbial pest control, particularly the use of entomopathogenic fungi (EPF) in insect pest management of cotton and pecan orchards.  One of my current research projects is to test the efficacy of a new strain of EPF versus commercial strains against cotton whiteflies, aphids, and pecan weevil as well as the commercializing potential.  Meanwhile, I am also interested in exploring the potential of EPF as endophytes to provide natural suppression of insect pests and plant diseases.  This includes both natural occurrence and inoculation of endophytic fungi in cotton and pecan.
