Research Summary

Research in the Chen lab currently focuses on six key areas:

  1. Advanced sampling techniques and accurate implicit solvent models
  2. Intrinsically disordered proteins: structure, function and disease
  3. Multi-scale simulation of fibril growth and nucleation
  4. Gating and regulation of BK channels and TMEM16 family proteins
  5. Computational characterization and design of novel functional peptides
  6. Advanced software for molecular modeling of small angle scattering
