I am an experienced animal nutritionist, wet lab microbiologist, molecular biologist, and bioinformatician with over 4 years of research focused on developing and testing antibiotic alternatives for production livestock. I hold a master’s degree in animal biotechnology from Dankook University (South Korea), with a focus on non-ruminant nutrition, and I am currently pursuing a Ph.D. in Animal Science at the University of Nebraska-Lincoln (USA), where my research centers on antimicrobial resistance (AMR) in pigs. My research bridges animal nutrition, microbiology, molecular biology, and bioinformatics. I am proficient in bioinformatics tools such as Unix/Linux command line, Python, and R, as well as microbiome analysis, host-microbe interactions, and microbial genomics. I am particularly passionate about using alternative approaches to mitigate AMR, such as genetic editing of microbes and investigating the role of mobile genetic elements. Furthermore, I am engaged in other microbiome research, including pig, cattle, and human studies, focusing on developing probiotics for livestock and humans. I also train and mentor high school, undergraduate, and graduate students, coordinate lab activities, and publish scientific research. My goal is to contribute to a sustainable and antibiotic-free future for animal agriculture.
