AREA OF EXPERTISE
My laboratory works on identifying biological control strategies for mildew and fungal pathogens of US crops.
RESEARCH INTERESTS
Our primary project focuses on understanding how secondary metabolite diversity and activity impact the biocontrol success of Bacillus strains. This information will provide knowledge into how to select the best Bacillus strain for the needs of U.S. farmers.
Our secondary project involves the identification of novel biocontrol molecules that can inhibit the growth and vitality of fungal or mildew pathogens that cause disease on U.S. crops.
