The expertise and background knowledge required come from the domains of Chemistry, Pharmaceutics, Pharmaceutical Technology, Chemical Engineering and Mechanical Engineering.  Accordingly the cluster brings together five complementary academic groupings (PIs and co-workers) as outlined in the table below
