Research Interests

The main focus of Dr. Schneider’s research has been on food safety, with particular emphasis on produce safety and food defense. The University of Florida is heavily involved in improving the quality and safety of fresh fruits and vegetables. Dr. Schneider’s program has been influenced by an increase in the number and frequency of foodborne illnesses associated with the consumption of raw fruits and vegetables. His on-going research program has examined etiologic factors, contamination mechanisms, and intervention strategies, as well as the production of educational materials.

Classes Taught

It is Dr. Schneider’s goal to have students leave the class prepared to enter a professional setting with the knowledge to be successful. For a discipline such as food science, an understanding of how this information is to be used in the real world is paramount. Since many food science students are preparing themselves for a career in the food industry, Dr. Schneider also believes in a strong interaction with industry professionals who can impart a unique perspective to student.
