Dr. Junmin Peng is a Member (Professor) in the Departments of Structural Biology and Developmental Neurobiology at St. Jude Children’s Research Hospital in Memphis, Tennessee, USA. He obtained his Ph.D. in Biochemistry at the University of Iowa and then received postdoctoral training in Neurobiology and Proteomics as a Jane Coffin Childs Fellow at Harvard Medical School. In 2002, he joined Emory University as a faculty member and moved to St. Jude in 2011. Dr. Peng has been strongly interested in developing high-throughput mass spectrometry-based proteomics, metabolomics, and systems biology approaches and applying these approaches to biomedical challenges (e.g., Alzheimer’s disease). Beyond big data analysis, his group also develops functional experiments to validate derived hypotheses in cellular and animal models. He contributes to the establishment of target-decoy strategies for protein and metabolite identification, the original profiling of ubiquitinated proteome and synaptic proteome, the identification of complex ubiquitin code, and the discovery of RNA splicing dysfunction and other novel disease proteins in Alzheimer’s disease. He has published 230+ peer-reviewed papers and has been invited to present his work at 110+ conferences, academic institutes, and companies. He has also trained 90+ graduate students, postdocs, and staff scientists. Dr. Peng also serves on the editorial boards of Molecular and Cellular Proteomics and Molecular Neurodegeneration.
