From 1998-2000 she served as an American Association for the Advancement of Science Risk Analysis Fellow at USDA. Prior to coming to JIFSAN, she was at the International Food Policy Research Institute where she conducted research to improve food and water safety along the value chains of poor producers. In the past, she worked at the Office of Risk Assessment and Cost-Benefit Analysis of the United States Department of Agriculture and at the Food and Agriculture Organization. She has also consulted for the World Bank and the Inter-American Institute for Cooperation on Agriculture. Recent research interests have been to identify cost-effective aflatoxin and avian flu risk reduction measures for economically disadvantaged producers in developing countries, and understanding the role of public-private partnerships in improving market access for the poor. Currently she is working to develop metrics to evaluate the impact of JIFSAN's food safety train-the-trainers programs. She has field experience in Brazil, China, Costa Rica, Ethiopia, Ghana, India, Indonesia, Kenya, Nigeria, Thailand, Mali, Mexico, Vietnam, and Zambia.

James Rushing, Ph.D.
Manager, International Training Programs
(941) 201-4603

Jim Rushing currently works with JIFSAN as the Manager of International Training Programs. He retired from Clemson University in 2008 where he held the rank of Professor and Center Director at the Coastal Research and Education Center in Charleston, SC. After retiring he worked almost two years as the Vice President one of the largest fruit and vegetable production companies in the U.S.

He earned the PhD in Horticultural Sciences from the University of Florida in 1985. During his 29 years of University service as a postharvest specialist, he took professional development sabbaticals. He spent three years as a self-employed consultant based in Santiago, Chile. Later he spent one year with the U.S. Food and Drug Administration (FDA) as a Visiting Scientist at the Center for Food Safety and Applied Nutrition in College Park, MD. He has worked in 36 countries in the fruit and vegetable industries.

Jim has been actively involved in fresh produce food safety issues since 1990 when he collaborated with the Centers for Disease Control to investigate outbreaks of Salmonella illness associated with produce from South Carolina. He went on to assist with various grant-funded food safety programs and has conducted training at the international, national, regional, state and county levels. He assisted JIFSAN with the development of a Train-the-Trainer Course for international audiences and has recently updated the training manual that is available at the JIFSAN website.

Angela Winslow, Ph.D.
Microbiologist, Research Associate
