Area(s) of Expertise
Dr. Walker’s research and extension focuses on improving the microbial safety and quality of poultry and poultry products. Her goal is to assist the poultry industry to mitigate the microbial safety risk and to ensure compliance with federal and state food safety regulations.
Research interest include:
• intervention technologies to control food-borne pathogens;
• predictive microbiology to estimate the growth and survival of the pathogens;
• thermal and non-thermal processing to improve the quality and safety of poultry products;
• rapid detection for food-borne pathogens;
• Cochlosoma disease in turkeys.
