Curriculum Vitae
Biographical Statement:

Professor Shu-Bing Qian received MSc and PhD degrees in Molecular Biology & Biochemistry with honors in 1997 and 2000, respectively, from Shanghai Jiaotong University Medical School (formerly Shanghai Second Medical University). 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.  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.

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, and the implications in human health and diseases. Specific disease aspects include but are not limited to, diabetes, cancer, aging and neurodegenerative disorders.

Teaching and Advising Statement:

Teaching is an exciting, enriching, and an integral component of an academic career, and I am firmly committed to excellence in teaching.  My primary goal is to instill interest and to expose students to the course topics, which in turn enables me to achieve a better understanding of the material taught, which then provides all parties an opportunity to learn new material.  Overall, I enjoy teaching and respect this responsibility as a core value and of critical importance to society.

Current Professional Activities:

Graduate Field Membership: Nutrition; Genetics & Development; Biochemistry, Molecular & Cellular Biology, Biological and Biomedical Sciences
Faculty Member: Center for Vertebrate Genomics
Faculty Member: Chemical Biology Interface (CBI) Program
Faculty Member: Leadership Program for Veterinary Students

Current Research Activities:

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. By focusing on chaperone network and the translation machinery, we are dedicated to elucidate fundamental principles of protein homeostasis.
