Our research focus concentrates on two areas: 

  1. Investigating strategies towards the total synthesis of complex natural products which contain caged bicyclic moieties within the carbon skeleton, these include the vibsanin family, diterpene alkaloids and tetranortriterpenes.
  2. Design, discovery and synthesis of novel biologically active molecules as lead candidates for the development of new medicines (e.g. anticancer and Alzheimers).
