Research Interests

My applied food microbiology research program is focused on dairy microbiology and food safety. I have one biosafety level 2 (BSL-2) Dairy Microbiology Laboratory and one food-grade Food Processing Laboratory. The research conducted in my laboratories focus on making food safe and healthy, and hence involves working with foodborne pathogens as well as probiotics. My research group works on fermented dairy products, improving probiotic longevity, utilizing whey, microbiological safety of dairy products (especially dairy powders), and removing biofilms from dairy processing surfaces. We conduct both in-lab and in-plant validations for food processing and antimicrobial interventions to control foodborne pathogens in dairy, beef, poultry, bakery, and pet foods. My research group has significant experience conducting thermal inactivation kinetic (D- and z-values) studies of various foodborne pathogens in different food matrices. My research group is also developing rapid identification techniques for pathogens in food and food processing environments using hyperspectral imaging. We are additionally working on studying the application of ultrafine bubble and nanobubble technology to improve food safety and quality. Please, visit my website for additional information about my research program and students.
