Dr. Kwangwook Kim recently completed his Ph.D. dissertation at the University of California Davis, with Dr. Yanhong Liu and is continuing his research as a postdoctoral scholar. His dissertation focused on the detrimental impacts of trace amounts of antibiotic and oligosaccharide-based polymer as a potential alternative to antibiotics on weaned pigs. Using an established enterotoxigenic E. coli challenge model, he concurrently examined the effects of trace amounts of antibiotic or oligosaccharide-based polymer on growth performance, diarrhea condition, local and systemic immunity, intestinal integrity, and changes in metabolic pathways and intestinal microflora of weaned pigs. Dr. Kim has published 8 peer-reviewed articles and 16 abstracts as the first author. Dr. Kim was awarded the 2022 ASAS Midwest Stahly/Peo Outstanding Graduate Student in Swine Nutrition, 2020 ASAS Midwest Animal Science Young Scholar, and won the first prize on the 2019 ASAS Midwest Graduate Oral Competition.
