Dr. Kwangwook Kim recently completed his Ph.D. program at the University of California, Davis, with Dr. Yanhong Liu. He is now continuing his research as a postdoctoral scholar. His dissertation focused on the detrimental impacts of trace amounts of antibiotics and oligosaccharide-based polymer as a potential alternative to antibiotics on weaned pigs. Using an established enterotoxigenic E. coli challenge model, he was able to concurrently study 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 six peer-reviewed articles and 15 abstracts as the first author. Dr. Kim’s honors include the 2020 ASAS Midwest Animal Science Young Scholars Award, the 2021 California Animal Nutrition Conference Scholarship, and first place in the 2019 ASAS Midwest Graduate Competition (Ph.D. Division).
