Research in my laboratory encompasses a range of studies that address the genetics of virulence and pathogenicity. The model systems used in our studies are members of the Burkholderia Cepacia Complex (BCC) composed of nine species. The BCC are recognized as significant pathogens in cystic fibrosis patients. We are currently studying secretion systems responsible for export of a cytotoxic protein(s) in both B. cepacia (plant pathogen) and B. cenocepacia (human pathogen) to determine common mechanisms for pathogenicity. In addition we are conducting genomic analysis of BCC bacteriophage.

PLPA 301: Plant Pathology (3Hr.) An introductory undergraduate level course in plant pathology. The course focuses on the disease causing agents, the result of the interaction between the pathogen and the plant, and the strategies used to control disease. Course is designed to provide the student with basic knowledge in plant pathology. Includes three lectures and a laboratory per week. The course syllabus, lecture schedule, lecture notes, instructional objectives, and course report information are listed on my course homepage. http://plantpathology.tamu.edu/index2.html

BESC 401: Bioenvironmental Microbiology (3Hr.) The course is structured to acquaint the student with the interaction of microorganisms (bacteria, fungi, protozoa, algae, and viruses) in diverse environments. The role of both biotic and abiotic factors in enhancing or deterring microbial interactions and growth is emphasized. Using the understanding of what affects microbial interactions and growth, the students are acquainted with the applied aspects of environmental microbiology; to include biodeterioation, pathogen control, pollution control, bioremediation, and the use of microorganisms as biosensors. Includes three lectures per week. The course syllabus, lecture schedule, lecture notes, instructional objectives, old exams, and course report information are listed on my course homepage.
