Research:

Areas of Research Interest and Expertise:

Diseases of cereal crops caused by fungi, bacteria, and viruses. Research is primarily with fungal diseases of maize and sorghum.

Areas of Research:

Major diseases (pathogens) occurring on sorghum and maize. These include: charcoal rot (Macrophomina phaseolina), sorghum downy mildew (Peronosclerospora sorghi), head smut (Sporisorium reilianum), aflatoxin (Aspergillus flavus), several foliar diseases, sorghum ergot (Claviceps africana) and grain mold (Fusarium moniliforme and F. thapsina).

Research areas for pathogens include ecology, survival, initial inoculum, pathogen variability, and host:parasite interaction (especially under stress environments). Part of a large interdisciplinary sorghum improvement team at Texas A&M that is active globally through INTSORMIL research activities.

Other sites that may be of interest:

INTSORMIL
American Seed Trade Association
Texas A&M University Department of Plant Pathology & Microbiology
