Carl K. Winter, Ph.D.

Position Title
Specialist in Cooperative Extension Emeritus

Food Science and Technology


Food Science (1991-2019)

Professor Winter retired in July of 2019. 


Ph. D. University of California at Davis, 1987


Dr. Winter researched the detection of pesticides and naturally-occurring toxins in foods, how to assess their risks and identify how to use the science in the regulatory decision-making process. His most recent work included looking at the relationships between crop production systems and naturally-occurring toxins. He also studied how to improve educational activities through incorporation of music into food safety curricula.
