Keshun Liu, M.Sc., Ph.D.
Born in rural China, Keshun Liu received his bachelor degree in Horticulture from Anhui Agricultural College (Hefei, China) and master and doctoral degrees in Food Science from Michigan State University, and did post-doctoral work at Coca-Cola Co. and University of Georgia. Currently, he is a research chemist at National Small Grains and Potato Research Unit, United States Department of Agriculture, Agricultural Research Service (USDA-ARS), Aberdeen, Idaho, conducting research on chemistry, processing, and utilization of grains, oilseeds, and biofuel co-products (such as distillers grains), and working with fish scientists to explore using plant-based materials for fish feed and other value added utilization. Prior to joining USDA-ARS, Keshun Liu was an employee at Monsanto Co. and University of Missouri-Columbia. Thus, he has over 26 years of research experience at academic institutions, private industries, and governmental agency in the field of food science and technology. So far, he has been author/co-author of more than 80 publications, wrote, edited or co-edited four reference books, and has been an invited speaker to both domestic and international audience for numerous occasions. He was a recipient of AOCS Award of Merit in 2010 and AOCS fellow in 2011.
