Hyunjun Choi
Postdoctoral researcher, North Carolina State University
Department of Animal Science
My research goal is to contribute to swine production through precision nutritional strategies:
Positively modulating mucosal microbiota, intestinal health, and growth in monogastric animals through dietary nutrition
Reducing pork production costs through precision nutritional evaluation of feedstuffs for monogastric animals.
Biography
Hyunjun Choi is a postdoctoral researcher in Animal Science at North Carolina State University. He was born on August 20th, 1992, in Pocheon, South Korea, and was raised in a family with a pig farm. He received his B.S. and M.S. degrees from Konkuk University. His Ph.D. research focuses on investigating dietary interventions using antimicrobial compounds and feed enzymes targeting anti-nutritional compounds, aimed at altering jejunal mucosal microbiota to benefit intestinal health by reducing pathogenic attachment and inflammation, thereby enhancing the growth performance of nursery pigs. To date, Mr. Choi has published 20 journal articles, with 13 articles as the first author. He has co-authored 2 book chapters and has presented numerous poster and oral presentations at Midwest and National American Society of Animal Science meetings. He served as President of the NCSU Korean Student Association (2022-2023). He has received several prestigious awards, including the CALS Outstanding Student Research Award (2025) from NC State University, the ASAS Young Scholar Award (2024) from the American Society of Animal Science, the Pinnacle Award (2023) from the International Ingredient Company—presented to outstanding graduate students in the U.S.—and the Communicators Graduate Fellowship (2022) from the North Carolina Pork Council.
