Professor Shu-Bing Qian received PhD degree from Shanghai Jiaotong University Medical School (formerly Shanghai Second Medical University), majoring in Molecular Biology & Biochemistry. He then conducted two postdoctoral fellowships at the National Institutes of Health (Bethesda, MD) and University of North Carolina (Chapel Hill, NC). Dr. Qian joined the Division of Nutritional Sciences at Cornell University in July 2008 and has been promoted to be an Associate Professor with tenure since 2014. In 2009, he received Young Investigator Award from Ellison Medical Foundation, and NIH Director's New Innovator Award. In 2010, Dr. Qian received DOD Development Award. In 2013, Dr. Qian received Peter Reeds Young Investigator Award. In 2014, Dr. Qian received DOD Idea Award. In 2016, Dr. Qian was selected as a HHMI Faculty Scholar. In 2018, Dr. Qian was selected as the Jamies Jamison Professor at Nutrition.
Most of the research work in Dr. Qian's laboratory is broadly interdisciplinary, with a primary emphasis on protein synthesis, nutrient signaling pathway, and stress response. Using biochemical, genetic, and cell biological approach, the Qian laboratory investigates translational control of gene expression, molecular mechanisms of adaptive stress response, dynamic mRNA modifications, and the implications in human health and diseases. Specific disease aspects include but are not limited to, diabetes, cancer, aging and neurodegenerative disorders.
How is mRNA translation controlled by nutrient signaling? How does protein folding and degradation occur during protein synthesis? How do cells get rid of misfolded proteins? These are a few of the problems we would like to understand. Elucidation of the molecular mechanisms underlying protein quality and quantity control will ultimately define new therapeutic strategies to human diseases such as cancer, diabetes, and neurodegenerative disorders.
Specifically, we use biochemistry, cell biological, and genetic approaches to study translational control of gene expression and protein triage (folding, degradation, and aggregation) using mammalian system. We established high resolutionribosomal profiling analysis to monitor mRNA translation, which allows us to investigate ribosome dynamics as well as co-translational events with unprecendeted resolution. In addition, we are actively investigating the role of mRNA modification in gene expression. By focusing on cellular stress response and the translation machinery, we are dedicated to elucidate fundamental principles of protein homeostasis.
