Associate Professor



Wei Qiang's research applies the biological solid-state nuclear magnetic resonance (NMR) spectroscopy and other biophysical, biochemistry and cell biology approaches to understand the mechanisms of b-amyloid-aggregation-induced neuronal cell toxicity and cell death. 

Current projects include: 

  1. Understanding the molecular and structural basis of non-specific membrane disruption along the process of b-amyloid aggregation. This project uses mainly solid-state NMR approaches to explore the structural and dynamic features of intermediate states in the process of membrane-associated amyloidosis. 
  2. Exploring the amyloid structural polymorphisms and cell disruption induced by the post-translational modified b-amyloid peptide variants. This project applies solid-state NMR spectroscopy, microscopy approaches and cell-based quantitative analysis.
