Dr. Wang’s research focus on isolation, structural characterisation and evaluation of natural peptides, performing structure-activity relationships to optimize the bioactivity of peptides as a method of rational drug design and in investigating the mechanisms of their action. A further area of research is the use of electrospray mass spectrometry employing MS/MS fragmentation to achieve the complete molecular characterisation of novel peptide/protein biomarkers of neuroendocrine cancers and in defining tumour subtypes according to their known variation in invasive and metastatic potential.
