Teaching activity

  • Pharmaceutics and drug delivery

Research interests

Computational pharmaceutics is to apply computer modelling technique on drug delivery to explore the mechanisms of drug delivery at the molecular level and then develop novel drug delivery systems:

  • Cyclodextrin-drug complexes; 

  • Solid dispersion; 

  • siRNA-polymer complexes.
