Dr. Junmin Peng is a Member (Professor) at St. Jude Children’s Research Hospital in Memphis, Tennessee, USA. He obtained his Ph.D. in Biochemistry at the University of Iowa, where he cloned the transcription elongation factor P-TEFb (CDK9/cyclin T) under the guidance of Dr. David Price. He then received postdoctoral training at Harvard Medical School as a Jane Coffin Childs Fellow, in Neurobiology (mentored by Dr. Li-Huei Tsai) and Proteomics (mentored by Dr. Steven Gygi). In 2002 he joined Emory University 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., ubiquitin biology, Alzheimer’s disease and cancer). 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, and the identification of complex ubiquitin code, and the discovery of RNA splicing dysfunction and a range of novel disease-correlated proteins in Alzheimer’s disease. He has published 230+ scientific papers, and has trained 90+ graduate students, postdocs and staff scientists.
