Dr. Ron Haff is the lead scientist of the Imaging, Detection and Sorting Lab (IDS Lab), a research project within the US Department of Agriculture, Agricultural Research Service, at the Western Regional Research Center in Albany, CA. He has served as Acting Research Leader for the Healthy Processed Foods Research Unit (HPFR), Acting Research Leader for the Foodborne Toxin Detection & Prevention Research Unit (FTDP), and Acting Research Leader for the Plant Mycotoxin Research Unit (PMR).

The mission of the IDS Lab is to develop sorters and physical/chemical methods to detect and remove defective, contaminated or otherwise undesirable product from agricultural project streams. These sorters improve the quality of fresh or packaged foods, remove unwanted transmission of materials deleterious to agriculture or health, and/or improve the competitive position of U.S. project in international trade. Such sorters will be in support of U.S. government action agencies and the U.S. food industry.

Please visit the Imaging, Detection and Sorting Lab homepage for detailed information on Dr. Haff and his staff's research.

 

The IDS Lab has over 30 years of experience in collaborating with industry in response to particular needs. If you are interested in collaborating with us, please either contact us directly or visit this link for information regarding formal collaborations with the Agricultural Research Service.
