Overview of Research Program

Bacterial adaptations to stressors (environment, plant, sanitizers, packaging) through cellular responses (biofilms, filaments, slow growing states), produce safety, sanitizer development, imaging and vehicles of foodborne pathogen cross contamination such as soil, compost, manures, water, dust, aerosols, particulates and food contact surfaces.
