GwangPyo Ko

Current affiliation:

Dr. Ko is the director at Center for Human and Environmental Microbiome, and professor at Seoul National University. Dr. Ko received Ph.D. degree from Harvard University, and did post-doctoral training at the University of North Carolina at Chapel Hill. He was a faculty at University of Texas HSC at Houston prior to joining to Seoul National University in 2005. Dr. Ko has successfully established and conducted an internationally recognized and highly regarded academic research program in the field of microbiome, and translational research. 


Current research:

His research has been focused on critical contemporary research needs in microbiome and health effects including metabolic syndromes, IBD, and women health. Dr. Ko’s group developed and identified the microbiological molecular markers through high through sequencing techniques and other novel techniques. In addition, his group evaluated the functional roles of specific microorganism and its metabolites as related to target diseases. The success of his research accomplishments is reflected in his record of scholarly publications in the peer-reviewed scientific literature, with more than 100 peer-reviewed articles.
