Jaeman Byun was born in Seoul, South Korea and received his Ph. D. under the training of Dr. Gross at Washington University, St. Louis, US. He then expanded his research efforts to clinical studies with state-of-art bioanalytical mass spectrometric tools during a post-doctoral fellowship with Jay Heinecke, MD, Washington University. Since joining Dr. Pennathur’s lab, he is involved in a number of original and creative ideas and approaches that have the potential to make a tremendous impact in clinical investigation and health care. His work has focused on the applications of biological mass spectrometry in disease pathogenesis with emphasis on oxidative mechanisms and biological mass spectrometry. He has actively participated in several studies focused on oxidative stress, proteomics, metabolomics and biomarker discovery in diabetic complications, chronic kidney disease, and cancer. His work enables early discovery of complications and develop novel therapeutic strategies.
