Dr. Carol Miles has diverse international experiences both growing up and in her early career where she has lived in subsistence agriculture communities in places such as Panama, Afghanistan, Cameroun, Malawi and Tanzania. Carol received her B.S. (1983) in Bio-Agricultural Science from Colorado State University, and her M.S. (1989) and Ph.D. (1993) in Vegetable Crops from the Department of Fruit and Vegetable Science at Cornell University. Carol’s goal has been to work with farmers to create sustainable production systems which provide a source of well-being to both the family and the community.

Travis Alexander grew up in Southern California, earned a B.S. in Biochemistry at the University of California, San Diego and an M.S. in Horticulture and Agronomy at the University of California, Davis. His masters’ research was focused on chilling injury in peaches for the fresh and canned fruit markets. His doctorate work focused on the postharvest implications of mechanization in the harvesting of cider apples. His work as Post-Doctoral Research Associate also involves cherry crops and a tea project. Travis is fluent in English and Spanish and currently working on speaking Russian.
