Soohyun Um is an Assistant Professor at Kookmin University, Republic of Korea. He received his Ph.D. from Seoul National University, where he trained in natural products chemistry under the mentorship of Prof. Dong-Chan Oh. His research focuses on the discovery, structural elucidation, and transformation of natural products derived from microbial and plant-associated systems. His work integrates mass spectrometry–based metabolomics, NMR spectroscopy, and genomic analysis to uncover new chemical entities and their biosynthetic origins. He has reported structurally unique metabolites, including lasso peptides and sulfur-containing natural products, and has explored microbial metabolism as a driver of chemical diversification. His recent studies have been published in journals such as Journal of the American Chemical Society, Nature Communications, Organic Letters, and ACS Chemical Biology. His current research aims to understand how microbial metabolism reshapes natural product structures and expands chemical space across diverse ecological contexts.
