Research Interests

Virus Diseases; Diagnostic Technology

My research involves the identification, characterization, and epidemiology of plant viruses and virus diseases, including those of tropical subtropical crops. Research activities include serology, electron microscopy, and insect transmission of plant viruses of cereals, legumes, vegetables and ornamentals, and characterization and molecular biology of badnaviruses.
