  • My lab focuses on the use of sanitation, beneficial microbes, and plant resistance to manage disease in several horticultural crops including greenhouse flowers, greenhouse vegetables, strawberries, quinoa, and tree fruit. My research explores the interactions between microbial biopesticides, plants, and the environment to identify best practices for integrated pest management. We specialize in biological control of plant diseases and the role microbes and their metabolites play in plant health, yield and quality.

    We are always on the lookout for new graduate students to join the lab. If you are excited by plants, microbes and agriculture please email me your CV and a brief description of your background and interests.
