Research Interests:

ST Cheung focuses on the investigation of molecular basis of human cancer, aim to improve treatment strategies and ultimately patient survival. The team has deciphered liver cancer expression profiles and metastasis associated genes. Continuation research included identification of potential therapeutic target, the novel growth factor granulin-epithelin precursor (GEP), and consolidated the roles on cancer growth, invasion, drug resistance, cancer stem cell properties, immunotherapy and antibody targeted therapy.


Specialised Research Area(s):

Novel Targeted Therapeutics; Drug Resistance; Cancer Immunotherapy
